I was wondering if the technology used in the 28BSST has found its way into any other Bryston products as of yet.

We are looking at that now.

You should start charging us a $1 each time one of us asks you that question.....again

Yes I guess it is a common question given the incredible response we have had to the 28B SST.

when one owns 3 28B's and is looking for a surround amp, I think its a worthy question.
how long before we can expect similar Bryston products?

Absolutely. A valid question. I've maybe asked James 3 times in the last 5 months and one of the reviewers from 6Moons asked a couple weeks back

However, for a 'surround amp', I would imagine any of the other SST series would do fine. I have a 6BSST now and it almost breaks my heart to think that an amp of that quality will be powering my back speakers soon (almost)

But, a set of 7BSSTs or a 14BSST (hopefully with the benefits of any tweaks from the subtle design changes in the 288BSST) is on the very short list of new amplifiers that I will be buying in a few months to power my fronts, so.....to the back speakers the 6B will go.

I would think a 3BSST would be more than enough for rears, and as James as said earlier, the design tweaks in the SST series that may trickle down will likely not be beneficial to the smaller amps, maybe only the bigger amps with more output devices, like the 600 watters.

Hi Keith,

Yes it is the Series amps like the 14B and the 7B's that will be affected.

[splittailz]

what I was hoping for was an updated 14BSST to power the surrounds. I can wait though. it will trickle down sooner or later. I have room and the power conditioning for another amp that size. maggies love power anyway.

Mr. Tanner:

Glad to come across this webboard first time today.  I e-mailed to ask Mr. B.Russell the same question back in April, because I'm planning to purchase the either 4B, 14B, or 7B's in Bangkok by the end of this year.

Does this means if I decide to go for the 4B, I don't have to wait for the trickling down?  Also, does the 20-year warranty applies for my purchase from your distributor in Thailand?

Please update in your company website as soon as the new 28Bs' techs apply to other SST amps.

Thank you & best regards,

Klao

Hi Klao,

Welcome sir.

The 28B trickle down applies more to the Series amplifiers like the 14B and 7B.  There may be some areas where we can apply the new ideas to the smaller amps but it will not be as significant a change.

Yes the warranty is covered if purchased through our authorized distributor in Thailand.

Sorry if this has been covered earlier, but what exactly is the technology being utilized in the 28B that is not in the 4B and 14B, and what effect does it have on performance/sound?

[James Tanner]

The main difference in the 28B SST amp from the earlier models revolve around the input stage of the
amplifier.

Where the single differential op-amp and inverter used to drive the power sections have been replaced with two differential amps in opposite phase resulting in a symmetrical signal path which together with tighter regulation provides for a cleaner lower distortion source.

This only affects the SERIES amplifiers - 7B and 14B.

Can say a already purchased 7B be updated?

How about the manufacturing technique: "wireless, gas-tight, gold to gold contacts" ?  I got this info from Stereophile's review of the 28B-SST, but I'm not sure whether the other SST amps have already used them.

[James Tanner]

Hi Klao,

Yes most of the other stuff mentioned in the review of the 28B amp are and have been used for a while in all our other amps.
There may be small areas where we can trickle down but most of the changes affect the 14 and 7B's.

James-

Any more news on this "trickle down" issue - i.e. are there any changes/upgrades expected on the 14B or 7B in the near future?  I'm strongly considering moving up from a 4B.

On a related question--can you compare/contrast the 14B and 7B?  Pros/cons of one 14B vs. a pair of 7B's?  (Driving a pair of B&W 802D's.)

Thanks!

Hi Rance,

We are looking at the trickle down issue as it applies to all the amplifiers but have not made any decisions yet as to what will be applicable for each different model.

The 7B has 2 advantages - it can be placed close to each speaker and use short speaker cables (always a plus in my opinion) and they can dissipate heat a bit better than a 14B due to there slight increase in heatsink surface area.

So if you had a very difficult load the 7B might be the better choice but under normal conditions with the amps on a stand and the average speaker load the 7B and 14B  would be very very close in performance.
