Rega Elicit R w/PSB speakers

I listen at reasonable levels
Classic Rock,bebop Jazz & Classical
I'm leaning toward Bryston Seperates
2.5 & 17
135w into 8ohms

That Bryston only has 180W into 4 ohms. I think a Bryston would be a good amp to drive PSBs, but remember the Synch One's impedance drops below 4 ohms, so I would think it might need higher power; it depends on the size of the power supply of that amp. If I remember correctly, you were missing the fullness of bass with your other amp.
But, I'll bet the 3BSST can drive your Synchs.

I'm auditioning 2.5 w/17 preamp coming next week..
I'll report back if it provides adequate power/bass

Hi Fishing716. How are the Brystons working out with the Synch Ones? How does the amp compare to the Acoustic Arts?

BTW, there is a new thread where a system sounds dynamic when first turned on, then later sounds weak. It's probably a different situation than yours since you were able to document the change in dynamics.
