Bryston 14B SST ot 7B SST

The difference between the two amps is in the power supply.The 7's use smaller capacitors,16 I believe,which provide a faster power supply whereas the 14 uses 4 large capacitors.The 14 also has a lower supply voltage.In terms of sound the differences are subtle but I would opt for the 7's as you have the advantage of running shorter speaker cables.

I opted for the 14bsst. It was a Stereophile class A choice about two years ago. I very much enjoy the sound from this amp. However you certainly can't go wrong with the 7's. Remember though, you will need another power cord and it would be best to run each monoblock into seperate dedicated lines...as opposed to powering both off one circuit. IMHO Bryston is a great choice.
