SUBJECT: TAVES - Bryston Demo – 2B Cubed

November 2016

Good Afternoon Mr. Tanner

I stopped by the Bryston room at TAVES a couple of weeks ago and thoroughly enjoyed the sound of Stevie Ray Vaughn's "Tin Pan Alley" that was playing - the system that you had set up was excellent and I was very impressed.

I wanted to tell you about the new 2.5B3 that day but it had not arrived at that time so you gave me your card and here I am.



I have been listening to the amp now for about a week and a half and the first words that we uttered after settling in to listen to this little beauty is ... WOW!

The bass is deeper and more detailed layers of bass are revealed. The soundstage is big and so 3 dimensional! Gorgeous front to back details and imaging. This is the best amp that I have had in my system to run so easily and so sonically and I am very pleased.

Congratulations on a great product from a happy customer in Ingersoll!

Regards,
Tom Ingram

SUBJECT: 28B Cubed Amplifiers Dealer Feedback

December 2016

Hi James

First, let me say that I am not someone to gush about new audio equipment; god knows I have had my share of gear.



We just got done installing the new Bryston 28B Cubed amps, and fired them up. Cold out of the box, they are freaking Amazing!

I mean they made my R1's sound like I have never heard before. They have so much authority, depth, finesse, dynamics, bass (like I never heard; 2nd time I said that) and imaging; I could just ramble on!

This is truly an anomaly in the audio industry, where an amplifier that retails at this price runs circles around it's competition.

James and Crew;

Kudo's for creating some of the finest electronics on the planet, at any price! The 28B Cubed amps are Astonishingly Good, run don't walk to your nearest dealer and hear them for yourself!

So much more to come; frankly, I am still stunned!

Ivan
P.S. - I just sold a pair of them from my very first demo!

[James Tanner - Bryston]

Hi Folks,

So after 2 weeks with my new 4B3 I can honestly say that it is really a wonderful amplifier!!

"The demo is everything" I agree 100% and I was lucky enough to have both the 4B3 and the 4BSST2 together at home connected to my system to help me decide.

My summation is "you don't know what you are missing until you hear it" or "you don't know what you are missing if you've never heard it" The SST2 is still a great amplifier and IMHO the 4B3 expands on all the things it does great and then adds a wider sound stage, black background of quietness, more separation of instruments, and more of a 3D effect of the music to give you that, your there feeling. Sad to have to sell the SST2, but didn't need both.

Time to enjoy some Christmas music with the 4B3!!

Hi Bryston,

I just wanted to tell you how much I'm enjoying my new 3B Cubed (number 000005 so I guess it may have one of the first shipped to the UK?). It replaces a 3B ST, which I bought second-hand ten years ago and which gave great service. But the 3B Cubed is simply light years ahead in performance - and it looks as good as it sounds.
Highly recommended!

And here's a great review in Dutch hi-fi mag Alpha-Audio that you haven't got listed in your review section: https://www.alpha-audio.nl/2016/05/r...yston-3b-sst3/

Hi James

Just a note:

I have compared the new Bryston 7B Cubed with the older 7B SST2 (as well as all the other Cubed amplifiers)

No competition James.

I think this is the biggest improvement in Bryston amplifier performance in the 24 years we have known each other.

He nails it! The 4B3 is just stupid good. Someone pairing the Maggie 1.7's and maybe a pair of REL subs with a 4B3 has a killer system for not a lot of money. Add the BDA3 and you will think you stole something. Without doing the math, I think that entire system would be in the $12-15k range.

Hi Folks,

We have a review coming on the new 7B Cubed Amplifiers and they asked us a number of detailed questions which I thought might be helpful.



MEMO: To All Bryston Customers
SUBJECT: Bryston 7B Q & A

June 2017

Technical Questions: Bryston 7B³

1.Bryston was founded in 1976 in Peterborough, right? Who was the founder? What was the first product – do you have a picture for me?
2.What are mainly the technical improvements to the predecessor?
3.Regarding the low distortion input buffer - what is so new/special?
4.What are the improvements concerning the output stage?
5.The bandwidth up to 100 kHz is larger than the bandwidth of the predecessor but compared to other amps in the same class it isn’t very high. What is the reason for the moderate bandwidth Bryston prefers obviously?
6.The 7B³ has the lowest damping factor/highest output impedance among the Bryston power amps. What is the reason for this? And do you think the sound of the 7B³ is as the result of this a little bit “special” compared to the other amps?
7.Do you have further information of the sense and the function of the Master Circuit Breaker? It seems like a unorthodox solution ...
8.How much is the VA of the toroidal transformer and the capacity of the filter capacitors?
9.What does “Energy storage power transformers“ mean?
10.How many output transistors work per channel and which type?
11.The circuit of the 7B³ is designed fully symmetrical?

ANSWERS:

Thanks for your inquiry. I shall answer your questions in order below:

1. Bryston was founded in 1962 in Toronto, by 3 people named Tony Bauer, Stan Rybb, and John Stoneborough. John Russell, ex-NASA engineer and the father of Brian Russell and Chris Russell, bought the company in 1968. Among Bryston's first products was an electronic blood-testing unit called the 'Aggregometer'. Bryston made its first audio amplifiers in 1973.

2. The technical differences between the 7B Squared and the 7B³ lie in the input buffer. It is a new, patented design by Dr. Alexandru Salomie, who worked with Bryston for several years. The input buffer has very low THD and noise, and it also is extremely good at rejecting power-supply artifacts, noise and RF on the input cables. The result seems to be better imaging, depth and silent background on the musical presentation.

3. The input buffer's patent refers to new compensation methods to stabilize the high-gain, extremely linear amplification circuit, as well as a novel input filtering system to reject common-mode noise and RF before they get into the amplification circuitry.

4. The output stages of the Cubed Series amps are not changed from the Squared Series. We are happy with how they perform.

5. No musical instrument produces tones or harmonics substantially above 20KHz. Thus, Bryston feels that allowing an audio product to produce full power to RF frequencies does not improve the musical presentation and can only potentially lead to 'trouble' in the reproduction. That is why we use an effective RF filter at the input.

6. The damping factor of the 7B³ is very similar to the 4B³ even though the 7B³ is a balanced output amplifier and the 4B³ is a single-ended output amplifier. This is because the output inductors on the 7B³ are a lower value. In fact, the effective damping factor on the 7B³ is normally higher than single-ended amplifiers because it can be placed very close to each speaker, with very short speaker cables.

7. The Master Circuit Breaker on Bryston amplifiers takes the place of a power fuse. It means the user does not have to find and purchase a replacement fuse if it fails, and it cannot be defeated or replaced with a potentially unsafe value.

8. The toridal transformer in each 7B³ is conservatively rated at 850W continuous, but has enormous excess capacity.

9. An energy storage transformer has a heavier-than-normal core to deliver a large internal magnetic field. This allows the transformer to deliver very high spikes of current from its energy storage when recharging the filter capacitors, instead of drawing directly from the wall through the power cord. That means much less Voltage 'sag' when delivering high power on crescendos, and maintains a much more stable sonic 'image'.

10. The 16 output transistors in each 7B³ are Bipolar types and use both NPN and PNP polarities on each half of the waveform for maximum linearity. Each transistor is rated at 230W and 16 Amps of current for a huge reserve of power handling capacity.

11. Yes, the 7B³ is completely symmetrical from input to output.

James

[GSOphile]

"6. The damping factor of the 7B³ is very similar to the 4B³ even though the 7B³ is a balanced output amplifier and the 4B³ is a single-ended output amplifier."

So James, would it be correct to say that the 7B3 is a fully balanced amp, whereas the 4B3 has balanced inputs but is not fully balanced throughout?

[James Tanner - Bryston]

Yes correct - the 4B is a fully balanced differential balanced input but runs single ended internally.

July 2017

14B Cubed 19 inch.JPG
The Verdict:

"I did not believe that the older Bryston 14B SST2 amplifier could be improved upon!

A bastion of neutrality, gobs of power and bipolar output, bass quickness that squeezed out the last ounce of low extension.


However, the new 14B has got that power slam and more, plus relays a sense of detail refinement in smoothness, imaging and upper-end "air" over the old one. Dare I say, it is even better than the old amp with hi-res music, such as DSD 5.6, and 24/352 PCM. And I thought the old 14B was already a good hi-res capable, high power amp.

The new Bryston 14B3 Cube is certainly an Everything Audio Network Stellar Sound Award winner and a candidate for amp of the year."

Hi Folks,

Another STELLAR review from down under on the new Bryston 4B Cubed:

Favourite Quote:

CONCLUSION

"A well-designed solid-state amplifier should fulfil the purest principles of music reproduction, accepting the input signal, then transparently and harmlessly delivering it to the transducers regardless of their inherent electrical demands, providing effortless and tight control of the drivers while manifesting boundless dynamic expression, detailed resolution and accurate tonality.

In the 4B³, Bryston has covered all these bases covered...for at least 20 years."

These amps are chameleons. They can totally change depending on preamp pairing. I have not tried a Bryston preamp, but paired with the VAC tube preamp they are OMG good! Awesome! Paul has tried his with an Air Tight tube preamp and also had great success.

September, 2017

“Good morning James,



Got the Bryston 28B Cubed amplifiers as planned and after a quick set-up, I had a first listen yesterday: OMG!

To be honest with you I did not expected a so big difference and instead of speaking within the regular terms employed in audio I will say:
Everything seems Sooooo easy now!

I have only tried my Pyramid speakers at this moment because one loudspeaker of my other pair is apart to begin the external cross over project but I do not have any doubt that these amplifiers will drive any speaker with ease.

Like I do with eveything I purchase, I took a quick look inside the amp and was very impressed by the simplicity and build quality, very, very good engineering inside! I also found the binding posts really nice.

I am already thinking of going active with a Bryston BAX-1 Digital Crossover.

Well I will stop right now bothering you with all my questions and wish you a very good day! I will do my best to be present at the TAVES in October and met you there if possible.”

[James Tanner - Bryston]

Here's another note of appreciation for the 4B3. I find it musical, neutral, non-irritating (like music), and unflappable. I tried a couple of esteemed & more expensive amps and prefer the uncolored quality of the 4B3. Very happy to have it in my system ... for a long time, I'm sure.

Oh, and it does all that without dumping hundreds of watts of heat into the room like some of the competition.

Well done! It deserves all those awards!

Hi James, What is sonic difference on 7B vs 14B ? Is there are any difference on these two ?

[James Tanner - Bryston]

Hi James, What is sonic difference on 7B vs 14B ? Is there are any difference on these two ?

Hi Paul,

The circuitry is the same in the 7B and the 14B but the 7B Cubed has double the power supply capacitance of the 14B per channel. That helps if you have speakers that go very low in impedance and need lots of current.

Thanks James, I can't believe how nice 4B3 cubed sounds is...I even prefer this little amp over 28B3 cubed. Weird @_@ !

I wish every one try them before they dump the money on super expensive amps. It's a hidden gem but without hearing you never can tell what you missing....

I haven't had a chance to hear the 7B3 yet. Wish I can hear them sometime soon

Hi Paul,

Thank for your kind comments on the 4B Cubed - it is a special amp indeed. Its tough though to get the message out as I think most people equate cost with quality.

As a 9bsst2 owner, as well as a 4b3 and 28b3 owner. I’ve got to say these were a leap forward. If you’re looking for amps, stop here. Incredible sound quality, incredible build, and THE warranty to top all warranties.
