Bryston 4B St vs newer SST

I have had the 3b-st with NHT-2.5, 4b-st with NHT 2.9, and 7b-sst with Revel Salons. I found the NHT and ST combos slightly fatiguing when it comes to extended periods of listening (over 6 hours a day). However, I can listen to the salon-sst combo all day (at moderate volumes).

I concur with the above statements about the bass control, detail, etc.. with the st and the sst lines. I cannot make statements about the improvements in detail or other sound attributes between the st and sst because I am comparing apples and oranges due to the differences in the speakers. But the important fact I wanted to add was the fatigue free nature that I observed with the sst line.

My buddy has the 4b-sst with Revel m20 speakers and it sounded increadible.

I have heard the Salons with ML 436 (?) amps and various other speakers with extremely expensive amps. I choose the sst line and have zero desire to change.

I now have the 4B-sst. The 4B-ST is much faster and has more bite to it.

hpilon, are you referring to the SST which is faster and having more bite?

Actually I am also cracking my head on which one to go for. The SST is above my budget wherease a used ST is much cheaper. Do you think I should stretch my budget and go for the SST or settle for the much cheaper ST considering the sound differences?

I am having Sonus Faber Grand Piano (older version) speakers. My current Classe CAP-100 integrated has insufficient power to drive the speakers. Please advice thanks. Personally I'd like to go for the 4B-ST and would appreciate if someone say,"Go ahead it will be fine" although the SST should be better.

I own the sst and auditioned the st against the sst. The sst is smoother and less fatigueing in my book. Because of that I hear more detail and enjoy the music more

I had a 4B-ST in use for mastering applications as well as critical listening and I can tell you without reservation that the SST amps are superior in EVERY category. If you want an amplifier to color the sound in any way, look elsewhere. If you want an amplifier to give you stellar resolution AND pack a wallop without flinching, get a Bryston SST. I am very pleased with my 4B-SST and have no desire to upgrade. The 4B-ST is a great amp. The 4B-SST just takes everything to a higher level.
