How did you get a SST upgraded to SST2? I asked that question of Bryston years ago and was told it could not be done, at least not in it's entirety.
I actually moved from a 4B-SST C series (pre-SST2) last fall to a pair of 28B-SST2's. Since it's not exactly a like for like (i.e. 4B-SST to 4B-SST2) due to the huge increase of available power on tap in the 28's so I can't say if the increased bottom end I hear is more a result of the 28's power vs. the SST2 design but there is more authority at lower frequencies. It's just more controlled and so quick. Aside from that I would be hard pressed to hear a difference which is good because I continue to use a 6B-SST C series for my center and surrounds and to be able to hear a big audible difference would really bother me so I am very pleased with the setup.
Since most of the time my system is just used for watching tv rather than listening to music, watching movies, etc. I'm not running very loud and because of that the 28's run very warm, basically hot and act like heaters in the room so I'm assuming they are running only in Class A at this stage. When I listen to music or watch movies I'm listening at increased volumes and the heat tends to dissipate a fair bit so I would assume they are running in A/B for that. In the summer the room gets ridiculously hot now with the 28's.
The original owner had his friend at Bryston upgrade all the internal circuitry to SST2, I saw the receipt showing "Replaced, transformer, all Caps and resisters" etc. I don't know what it cost him, but she's a beauty of an amp!
I was interested in switching to separate individual mono blocks and thought the 28's would do fine, I was hoping the 28SST2 would do more than a mere 10W in class A, I suppose I could just acquire a more efficient set of speakers for low level listening, my current Paradigm Studio 100v2 will eventually be replaced, a friend who built his own speakers that were professionally assessed at a sound quality that is equal to a $150K pair of speakers, he's offered to build me an amazing set for about 8-10K.
My other option is to go with a pair of Pass Labs XA100.5 or Levinson 532's, however I've read that the Pass Labs has a tendency to sound dry, also the bass on the Pass Labs is not quick enough for most listeners.
I admit that I do like my 4B SST2 mated to my Benchmark DAC2 HGC playing DSD audio (so frustrating as I find it exceedingly difficult to find good quality DSD recordings, if anyone has any suggestions on very well recorded DSD or SACD selections, that would be great).
I just sold my BP26 /w MPS2 as I was clearly able to distinguish that the Benchmark DAC2 was simply so much more transparent as a stand alone Pre/DAC.
My current (humble) audio system...
Bryston 4B SST2
Benchmark DAC2 HGC
OPPO 103D
Pioneer Elite VSX94THX
Paradigm Studio 100v2
SVS SB13 Ultra
Blue Circle Noise Hounds x2
Transparent Interconnects
PC Audio Power Cables
MIT Terminator Speaker conduits
Macbook pro (late 2012 ver.)
Audirvana 1.5.1.2
I'm using an Active USB cable due to the distance between the Mac and the DAC.
Yes the wires are a mess cause I'm constantly trying to ideas.
