Bryston 3bst vs Bryston 3b


What are the differences? Have found a 3b for $400.00 but cannot find specs or reviews. Does the 3b stack up against the newer amps in the $5-600 used (ATI 1502, Rotel 1070, Anthem mca2) range? Suggestions appreciated.
Thanks

If you can afford it, I go for the 3B-ST also if Bryston is what you want. There is a lot of competition in the $2000 List - 100/125 watt amp market, but it seems like every review I read about concerning another amplifier in this range, the reviewer seems to always compare the amplifier under review with the Bryston 3B-ST. This tells me it is the one to beat. I personally have a Blue Circle BC22. I love it. It was a better match for my system. The Bryston was on my short list and I would have probably been just as happy with it.
My dealer had an old 3b. It sounded fairly harsh throughout all frequencies when I listened to it.

I now have a 4b st. I love it, and it will have to be pryed from my dead cold fingers if anyone wants it. It is a wonderful amplifier; fast, tight bass and great detail.

I know this is a 3b vs 4bst comparison, but it seems consistent with other people's experiences and with the company's own "propaganda".

The 4b st may give you more dynamic headroom for those musical transients, and make your speakers just sound "bigger".

Hope this helps
After accidently shorting out my wonderful pair of Audire 125 wpc Audires, I am using a 3b and a 4b.  They actually sound pretty good, but they pale in comparison to what I am used to.  I guess that when you compare a 200 wpc amp with 2 375 watt transformers, 4 4600 mf caps, and 8 outputs with my 125 watt Audires, each with 2 500 watt transformers, 12 big Motorola 1500 watt outputs, and 8 26000 mf caps, it is easy to guess which one sounds better.  FYI, the difference between the Audire 125 watt amp and the 4b is much greater than between the 4b and 3b. Alas, Julius got dementia and bo longer repairs his product.  For the first time in. 40 years, he did not answer the phone at Audire when I called.
