The 4B SST2 *IS* an awesome amplifier. Did you hear the latest version or one from before 02 - 2010?
If not, the serial numbers over 004719 have different capacitors and sound even better. And hooked up to a top class pre amplifier it will REALLY show its teeth...
As for RCA vs XLR... Try both and use the one you prefer.
You are correct.
Hi Tim,
As far as I know, it was a current, new model. I was absolutely amazed how good it sounded. Kudos to Bryston!
