hi guys in this episode of the Clone

Wars we'll talk about bommaster 933 Mark

I clone amplifier produced by Breeze

audio called also Breeze high-fi uh yes

the original amplifier was produced

between 1996 and 2004 and it was pure

power amplifier with balanced XLR inputs

only uh this clone is based on the

internal structure and on the principles

and diagrams of original amplifier

however it has additional volume control

here and it's using single-ended inputs

uh it doesn't have any balanced inputs

whatsoever um yes um the

specifications uh this is uh basing on X

amp Build architecture it's using this

coupling so we'll see some operational

amplifiers inside uh the power to

specification uh on paper is 70 wats

into 8 ohms and 120 wats into 4 Ohms uh

but the U the shop U the store also um

provides additional information that the

actual measured uh Power output was uh

almost 150 watts uh for for ohms so

that's quite nice uh uh I got this clone

uh because of uh the numbers uh and

branding uh but the numbers that uh made

me uh think about it uh were uh three

things the first one dumping Factor it

has a huge dumping faor Factor because

according to the data it's 3,000 so The

Dumping factor for this amplifi is 3000s

that means that the terrorist says that

it should be able to stop the membranes

of your speakers in place uh another uh

interesting number is total Harmony

Distortion uh according to the

manufacturer data THD for this

amplifier uh is between

0.002% at 10 wats so 10 watts would be

your regular listening level probably uh

and uh it goes up to up to

0.011 at 70 Watts 70 Watts uh for the

most for would be uh I don't know uh

defining level uh so that's still very

very clean in both cases these are very

very low harmonic Distortion numbers and

the third number that made me uh pick

this amplifier is signal to noise ratio

uh it reaches 107 DB which means that

the distance between the noise flow and

the signal uh level uh is uh way above

100 DB so so pretty pretty good numbers on

paper uh what I've measured here when I

was uh doing the tests uh is the fusing

keys that the noise floor is uh actually

very very low uh you can you can't hear

any kind of hising even with uh very

sensitive uh motion Transformer speakers

uh when you'll get your ear to the

speaker and you'll Max the volume it's

still that silence

also no hum from the Transformer

whatsoever but we'll get to that uh I've

measured the power usage the power

consumption at uh 36 Watts when idle and

40 Watts uh when playing music the

temperature the temperatures you might

say were very very healthy because uh

they were between 36 and

37° centigrade yes uh this amplifier

comes into uh two flavors you can choose

between two external chassis uh this one

is actually the cheaper version uh I got

it uh for

$250 shipping excluded and shipping was

about uhu $50 I think uh shipping to

Europe so all in all

$300 uh for this version uh the more

expensive version uses CNC machined uh

chassi also made from aluminium but uh

the other version uh looks almost

exactly like the musical uh Fidelity A1

clone that I reviewed uh so I like the

look of this particular chassi better

and I didn't want to have two amplifiers

looking almost exactly the same so the

fact that this actually is cheaper was

additional bonus for me uh uh yeah

threat from verat speaker verstat German

YouTuber uh threat from speaker

verat uh has a short review of this more

expensive version so you can take a look

at the more expensive chassis and you

also will be able to uh take a peek

inside of the

amplifier uh there is one difference

between this unit and the one that he

got uh the capacitors power bank

capacitors are different branded uh but

more on that later

yes so what do you get for your $250

$250

uh the front power switch power LED

which looks very nice because of this

small place uh hidden here uh when it's

uh lighting up uh this whole area is wed

so it looks very nice uh volume pot here

and a very funny thing uh in front of it

uh very lucky typo uh so you don't have

boom here but you have boomster here boomster

boomster

933 high-fi

amplifier yes On The

Backs we have solid aluminum fins very

good and in the back we have speaker

tabs quite good looking and solid

speaker tabs that will accept uh B wire

spade and banana

connectors uh they are looking quite

nice we have RCA connectors for left and

right channels uh we have input voltage

selector because this can operate on

110 uh volts power grids uh we have uh

power cord connector and integrated fuse

compartment here uh the specification

says that the actual model number is PA

933 uh the model with the more expensive

chass has Dash and uh two number two at

the end and it also says that it's

specified for 120 watts per

channel uh the whole amplifier weighs

around 10 kilos it's very small it's

very compact but it's quite

heavy yes the build quality the build

quality the build quality is excellent

It's solid aluminum and that kind of

build quality is actually spoiling me

because I came to expect that kind of

build quality on the amplifiers that I'm

reviewing so unfortunately all our local

Brands will have a hard time now because

I'll be expecting at at least 3 to 4 mm

thickness on the

chassis yes what's

inside uh inside of this amplifier uh we

have toal Transformer with uh thick

shielding uh which is actually actually

very good and it's not quite common on

the power amplifiers that I reviewed

some of them uh had just bar

Transformers uh in the open uh The

Shield is nice uh because it provides

additional shielding from Emi uh for the

uh left and right channel boards uh we

have some nice ceramic resistors here uh

all of the red capacitors are German

VMAs uh which is very nice uh the

transistors are sunkens let's take a

look at them

y uh we also have uh Ron transparent

relays uh what we don't see here is that

we do not have any kind of internal

fuses on the boards inside of the

amplifier the only uh fuse is in the

back in this compartment I'm mentioning

because I'm mentioning this because some

of the other amplifiers that I reviewed

uh had also additional fuses inside uh

but that's that's that's perfectly fine

this one should be uh good enough

uh yes uh the main capacitor Banks uh

each one of these capacitors is uh

10,000 microfarads rated for 63 volts

and they are they are produced by a

light I don't know the brand if you

happen to see that b earlier you may

give me a shout in the comments so that

would be one of the things to upgrade in

the future uh the other interesting

thing is

that the rectifiers here are using head

SNS uh which is also not very common and

actually I'd say that may be very rare

uh in other equipment that I reviewed

you can see that the boards are marked

with uh bumas 933 Mark I version three I

suppose that's the version of the PCB

board uh yes we have blue Alps for

volume control and we have one thing

that I don't really like uh here and

I've already mentioned mentioned that in

my first look video uh the LCA inputs

are going from the back of the amplifier

to this symmetrical

connectors uh on the PCB symmetrical

because the other PCB looks exactly the

same but it's just mirror design so your

input signal travels then along the PCB

board Edge right up to this point and

then it goes to the connector that moves

that yes so uh the track is too long I

don't like that idea idea and uh since

uh I'm planning to bypass the volum pots

uh volum pot anyway uh I will

be making uh cable that will be running

straight from RCA input some kind of

good quality to shielded cable I don't

know from Mami uh maybe some kind of

microphone cable from canar or Sumer uh

and the cable will be running from the

RCA straight the board you have marked

uh right input and ground uh points here

and left input and and ground points

here uh so I'll probably uh use uh

separate C for that in order to be able

to uh get back to the stock connection

Set uh the other thing worth mentioning

is that uh these the cables that are

connecting the speaker output from the

board to the actual speaker tabs uh are

also candidates uh for maybe replacing

with something ther and better quality

and uh at the same time uh I would just

order anything straight to the tabs and

and the board um but uh the connectors

used here are not exactly a bad solution

uh the idea uh for using them is very

simple uh This is highly modular build

and it's very easy to uh remove

everything to disconnect all of the

cables and to get access to the boards

uh which is a very good thing if you're

going to be servicing this unit or if

you will be uh doing some uh molds like

for example replacing capacitors uh it's

a very good thing because in order to

get to the bottom of the PCB you don't

have to theholder any kind of theholder

any kind of cable you just need to

unplug everything so that's it uh yes uh

we have some transparent on on relays

here uh we have head SNS on

the rectifiers which is a very nice

thing because it's one of the the few

that has them uh and I think that's it

about the internal build uh another look

on the sun

transistors and that's

it uh

yes so all in all I like the build build

inside I like the quality of the

components used here it does leave some

room for improvement if you're into little

little

it yourself uh you can you can replace

some things uh yes

now we've covered the build the

specification the internals let's talk

about the most important thing of the

review let's talk about the sound

quality of this

amplifier uh well I've divided this

section into the usual Parts uh so let's

start with the base uh the base of this

on this amplifier is very strong and it

gives very solid uh foundation for all

of your music and it has absolutely

great texture uh the one of the um

positives of having such a high dumping

factor is that uh you're controlling the

membranes of the speakers very precisely

uh so this translates into very

involving uh sound into very involving

base uh that makes you track everything

that's happening down below uh all of

the BS guitar lines uh all of the BS

textures present there are absolutely

Splendid uh the base doesn't hold back

uh it's very strong it fills the whole

room uh with the base uh but it's not

the thick muddy type of Base it gives

the solid foundation and it's just

everywhere so yeah I absolutely love uh

the base on this

amplifier um

the important thing to note here I think

this is the first time that I'm noting

this uh in um review uh of any of power

amplifiers that I got so far uh is that

the this base is a very uh rhythmic one

it makes you tap your foot it kind of

reminds me uh in this regard uh nine uh

units that I had in my time uh I had

nine Unity cutes two versions of unity

cute and I had uh one of smaller NN uh

Power amplifiers um and this amplifier

also has this uh quality uh I'm not

saying that the other ones were not

rythmic but this one will make you tap

your food to almost

everything uh including uh some

classical music uh the great example for

that would be Topsy uh Topsy uh is so WR

here that you in voluntar uh will use

your hands or your feet to tap to the

written um yes going to the MS uh the MS

are full bodied uh and uh we have very

natural sized

voices uh the piano the piano here uh

was very detailed uh very uh melodical

but also full-sized uh you didn't have

that uh idea that the sound of the piano

comes from some point in space but you

actually listening to the amplifier you

actually feel like the piano is a big

instrument and you can actually hear the

size of this instrument I know this sign

sounds weird especially for someone who

never heard uh or is about to hear for

the first time uh good quality amplifier

but uh for those of you that have some

um possibility to hear a good quality

audio stuff you'll know what I'm talking

about uh you can actually hear the size

of the instruments and with this

amplifier the same goes for brass

instruments uh they are very detailed

they have very nice textures but also at

the same time you almost able to hear

the size and the weight and the

solidness the the of the instrument the

fact that it's made uh from metal and

that it has some uh weight behind the

sound so that's also very surprising

especially given the price that was only

$250 that's wow uh okay another thing

that I've noted here uh it's

detailed uh and the coral songs uh these

convey a lot of emotion um and what's

important uh they are detailed so you

are able toar the distinct voices uh

within the cor uh it's not like one

sound of the group of people singing

together but you can actually hear the

members of the car singing together

that's very important and it's that

that's very uh good thing in my book uh

but at the same time uh there is no

listening faure and no uh calance

whatsoever here and the Seance gets us

to tble

uh no the t is not cilant the t is very well

well

extended uh it's uh it

um at the beginning when I started my

session I thought that rebble is a

little bit dry but then I

realized that uh I didn't let the

amplifier uh to get warm and I've waited

for like 10 and 15 minutes and the tble

was perfectly fine so the thing to note

here and I repeat that at the end of the

review is that this amplifier sounds

best after something like 15 minutes of

warm up uh it reaches this 36 57°

centigrade and it sounds best then uh so

very extended very transparent uh treble

maybe maybe they could use a little bit

more of the top uh and air but that's

just a small amount and this may come

from the two things the first one is

that uh I'm electrostat guy so I love

plenty of air at the top end and the

second thing is that U since uh you're

hearing the instruments with the full

size sizes uh this means that maybe I'm

perceiving the sound uh

uh how to say that uh how should I word

that uh if the size s of the instruments

are bigger then the spaces between them

will be a little smaller so maybe that's

something that I'm perceiving uh and

that would actually translate into a

very good trait of this amplifier so

anyway the treble

extended good precise detailed no

listening F uh fatigu uh no Cilan

whatsoever uh and one thing to note here

it's very delicate and musical uh the

symbols on Dance of the witches by John

Williams were absolutely stunning um

yeah I think I make a video on the TX

that I'm using uh for test purposes so

anyway Dance of the witches is one of

them and the symbols in that songs in

that song we're absolutely great with that

that

amplifier moving on to the detail uh

closing the Travel section and moving to the

the

detail the tble is very good and very

precise but this is the type of the uh

detail that's not in your face uh the

amplifier doesn't push uh detailed

information in your face and it's not

forcing you to focus on the details uh

but at the same time everything is still there

there

you can uh focus on single instrument

you can focus on single voice and get

all of the detailed information that's

hidden in the track so that's very very

very good in my opinion uh because it's

musical it's not analytical but at the

same time all of the detail information

all of the analytical side of the music

is still present there so that's a very

good point here

uh I love the details on that one uh and

the detail detail sorry my problems uh

the detail um moves us towards uh scene

and imaging uh this amplifier has a very

good Center image uh the instruments as

I said are full-sized the stereo Imaging

is also very

precise uh it's able to easily get the

sound away from the speakers uh when you

close your eyes listening to the music

uh you have no uh feeling whatsoever

that you're listening to two

speakers uh once you close your eyes the

sound gets away from the speakers uh

it's in the front of them and it's gets

and it gets very wide so that's that's

uh also another very good

trade uh the it's not the 3D imaging

King uh because uh the depth information

and height information were there uh

they were not as uh on the same level as

in best amplifiers that I've tested so

far uh but they were nevertheless very

very good the best was left and right IM

much there was death information there

was some he

information uh it was not the best in

theout but it was uh very very good

nevertheless uh I will have to as I

wrote a couple of times already I'll

have to do detailed comparations uh

between different amplifiers uh

different listening sessions and then

I'll be able to uh determine the exact

uh quality of the scene here but it's

very good it is very

good uh yes

um when I finished my in sessions with

my Dynamic speakers and by the way the

equipment uh used for the testing

sessions uh will be described in the uh

video description uh the the detailed

information uh will be uh provided there

uh when I finished my regular listening

sessions as you probably know uh at the

end I'm switching the speakers to my

electrostat speakers because these are

like uh x-rays x-rays for audio equipment

equipment

uh and I'm uh doing the listening

session again I'm checking uh what's

changed uh with my uh Martin Logans

because they reveal everything and uh in

this case I have just uh a few notes uh

the first one about Imaging yes Imaging

uh for the death and height could be a

little better better but uh what's

interesting uh is the fact that the

separation between instruments was

excellent so very good stereo

information uh a little less information

on the depth and on the head but at the

same time the um very precise

information uh on the

separation so the instruments and the

sounds were not blending together but

they are very clearly separated and that

was very nice

thing uh uh yes uh one more thing uh

that maybe uh should be obvious by now

this amplifier was able to properly

drive my

electrostats and that's not something

very common uh these are a very

difficult load because uh they don't

have a very high sensitivity uh they

have 90 DBS and the piggest problem is

that they present a difficult load

because the tble the top end in region

of 20 kils uh makes them go to as low as

1.5 ohms uh 1.2 ohms uh which means that

uh it's very hard uh for most of the

amplifier to give proper proper able

extension with electrostats and this

little Powerful Beast could do that the

Reel was absolutely very very good uh

the extension was proper the detail was

there the airiness was there so yeah

small but

powerful uh yes and

uh this uh arrives us to uh the last

part of the review uh my loose thoughts

and the summary uh loose thoughts as

usually I have different things that

I've noted during listening sessions

that do not exactly fall into uh

previously uh this categories so the

first thing uh this amplifier I think

may be a bit of the on the darker side

because uh of the base I said the base

is everywhere uh so it's not light and

air there's no fair is flying around

it's a little bit on a darker side but

not exactly warmer side uh and I like

that I really like that it was a very

nice pairing with my

electrostats uh yes another thing that

I've noted uh is uh that the base was

absolutely stunning yes the dynamic

swings were also absolutely stunning it

can go from very quiet to very loud in a

second and it can go from very loud to

very quiet in another second stopping

your speakers in place uh once again

High dumping Factor uh yes the good

sense of Rhythm and feeling of power

that's something something that uh

you'll get when you're listening to this

particular device for

example uh for the for being powerful

and the written uh London F harmonic

Orchestra uh made a uh set of recordings

uh with uh computer games music and uh

Listen to Call of Duty Modern Warfare uh

main uh Team uh from that set of

recordings by the way I highly recommend

the whole

um the whole CD um yeah uh this mic uh

qualities as I said are reminding me of

uh names uh it's a fun um that makes you

want to go louder and louder and uh

that's actually true I during my Lessing

sessions uh my wife shouted to me that

the other people living in other part so

maybe I should tune the room down

because it makes you want to go louder

you want to feel the Earth tremble the

base is so good here and it was fun

until I had to lower the volume

but once in a while yeah uh okay as I

said it needs about 15 to 20 minutes to

sound best so that's a interesting thing

most of the solid state amplifiers uh do

improve their sound after a while uh but

it's quite short uh this one yeah 15 to 20

20 minutes

minutes

uh one thing worth noting here is that

if you're following my channel I've

already reviewed a couple of power

amplifiers this one is different this

one is really really different it has a

very interesting signature a signature

that I loved it's very fun it's very

powerful uh but it is

different uh you always ask me which one

is better

and I always say at this level the

competition is so close that it's not

about who is better because there is no

one single amplifier that is worse they

are different flavors they differ in the

way they present the sound so you should

get one that will be uh maybe not not up

to your standards but uh that will fit

your partic particular uh listening

habits the best so anyway

this one is so good and it's so fun and

it's so different uh that regardless of

the outcome of my quest to get the best

amplifier for my electrostats this one

stays in my collection it's so good it's

so small and it's so powerful that I

want to have it it needs to stay with

me uh if I would have to coin the slogan

to Market this thing I would say that

this is a small box of condensed power

and fun

uh that's also something that I noted here

here

um uh for for those of you that would

like to mod this amplifier maybe a

little like me uh one parting thought on

moding is uh that there is a moding

potential here the wires uh maybe the

capacitors Etc uh but yes I will change

the wires yes I will bypass the pots but

I'm a really afraid to touch anything

else including cups not because I break

something but because I really really do

like the sound quality and I am afraid

that if I use some better Parts I will

destroy this uh delicate State uh this

uh delicate Harmony between base and

Trel here um I've also noted that some

of the capacitors on the

board like these ones have uh higher

values than the descriptions on the

boards I've asked about that b I

contacted the manufacturer about that

and once I have the explanation for that

I let you know I'm mentioning this now

because uh there are usually two cases

uh for such situation the first one is

uh when you're changing the the values

of uh elements uh on the board because

your listening sessions say that you

should slightly change them the second

one is uh when you're having the

available stock of components and you

replacing capacitors with the next

closest Value because you don't have the

particular value uh in your stock and it

doesn't change the change the sound

signature uh nevertheless uh I've asked

Bree about that and I'll post uh answer

in the descript description of the video

but for

now seriously guys I'm quite terrified

to change anything here except the wires

here yeah because the wires will not

affect the sound that much and the

changing wires here will not affect the

sound in any kind of negative way this

input signals bypassing the volume pot

that's that's not that's nothing it will

improve the sound but everything else

I am afraid to touch

it uh okay

one Lal One summary for the end of the

uh sound quality part for the money it's

absolutely Nob brainer don't think about

that don't wonder if you should get one

or not if your bus l or not just buy one for

for

$250 and compare it to your other amplifier

amplifier

it's so different and so fun and so

powerful and precise at the same time

that it should be a part of everyone's

collection and one more thing this was

my first contact with bras CL uh you'll

probably aware that there are two um

available two others available on the

AliExpress the first one is B Master uh

99 and the second one is B 956

and this little guy made me very

seriously wonder about getting the other

two it is so good that I really want to

hear the bigger and more expensive

Brothers of this

amplifier so I hope you enjoy this video

stay tuned for other videos I have a

quite large collection of the stuff that

I wanted to show you here we have

another set of uh preamps and Hood

amplifier that are burning in right now

I'll be getting back to my cable reviews

yes you see fake noost Valhalla too

getting burned in there if you have uh

any questions feel free to ask them in

the comments I am trying to answer all

of the questions and all of the comments

usually uh once or twice per day uh so

you shouldn't wait uh very long uh if

you like that video and you if you feel

like you'd like to buy me a beer I'm a

beer guy and you can do that using

supers or donations or whatsoever I

drink to your health uh yeah stay tuned

for other videos that will be coming
