Looking for feedback on The New capacitors that Bryston is installing in their Amps.

Regards Robert

Hi Robert,

INPUT CAPACITOR CHANGE and FEEDBACK CAPACITOR CHANGE:
We have implemented the use of some very specialized capacitors in a number of key areas in the circuitry. There is a consistent improvement at high frequencies near and above 20K, and up to over 60KHz. These specialized capacitors are installed at both the input stage and the feedback loop of the amplifier circuitry. These capacitor changes affect all new SST² amplifiers.

The upgrade is only available for ‘SST²’ amplifiers ‘NOT SST’ or previous models.

At Bryston we are continually trying to improve the performance of our products. Please be aware that these changes are 'evolutionary' not 'revolutionary' in nature. They will provide subtle to noticeable improvements depending on your specific system and setup.

If you can spare the money for it: do it. It is worth it.
I went for the slightly more radical road and just bought a whole new amp (also because my old 4B SST2 was silver, the new one is black).
In my opinion James is rather modest here, with the 4B SST2 model at least the change is quite significant.

Here are my 2 Babies

Looking forward to them coming back...
They have not been sent in yet

I did notice a difference in the audio between the amplifier I auditioned in the showroom compared to my “post” modified amplifier that I purchased. At the time, I thought that it was all about the difference in room acoustics - I see that there was much more to this.

Be well...

James what is the turn around time to have the New capacitors installed?

Thanks Robert

About a week from when we receive it.

Hello James and all the gang. Are all sst2 amps manufactured from this date onwards will have these improve caps? What serial number on a 4b sst2 should I make sure I get from my local dealer ( don't want the old stock by mistake) Tnaks again..........

James,
This post would be good to make a 'sticky' in your forum, for future reference

Hi Bill,

Yes it is there already. I was just being redundant - redundant:

Hi James

First post so please be gentle

Is the 9BSST not being updated in the same way, I notice it is not on your list?

Cheers

Hi Alpha,

Gentle it is sir! Yes it is in the works. The problem is the size of the new capacitors are larger than the previous version so we have to do some modifications on the circuit boards to allow for the new caps.

Excellent news, do you have a timescale for the works?

Thanks

I will check.

As of last week the 9B and 6B have the new input capacitors.

Any price increases on a 4b sst2 amp? Thanks.
