Plinius SA301 Or Bryston 4bsst2?

Plinius SB301 is in a different league from bryston 4bsst2.
It will be better for you to compare Plinius SB301 with bryston 14bsst2. I would still vote plinius for its midrange/bass quality. In addition reliability of plinius is outstanding. I wish I could afford their plinius Ref SA amplifier.

That's what I figured. The 4BSST or SST2 is not the most transparent or dynamic amp out there.

Ok, cool, sounds good regarding the reliability. Why, what is the price of the Ref SA?

Something that hasn't been mentioned but should be considered is that the Plinius SB-301 has unusually high gain, the specs being 32 db unbalanced and 38 db balanced. So with that amp you would find yourself using the volume control on your preamp at significantly lower settings than with most other amps, including the 4BSST2. Especially if you are planning to go with a balanced connection to the preamp.

That may be good, bad, or neither depending on the output level of your source(s), the gain of your preamp, and the sensitivity of the speaker (the latter being moderate, at 88 db/2.83 volts/1 meter per Stereophile's measurements, corresponding to 85 db/1 watt/1 meter given its 4 ohm nominal impedance). And possibly depending also on how well your volume control maintains resolution and channel balance in the lower part of its range.

Good luck. Regards,

I've heard a Bryston 4B SST driving a Thiel 2.3 and i'm 99%+ sure it was a very poor match!
