Rega Elicit R w/PSB speakers

no my dealer didn't want to lend any amps

I tried Accustic Arts(power 1 mk.3) & got good results
Regret sending it back...
I wasn't satisfied with built in phono stage
May repurchase w/o phono & add MF M1 vinyl.

The Acoustic Arts is a nice amp, but a weak built-in phono stage is often the case.

Powering my PSB Sync Ones with my solid state Ayre integrated - love it.

How many watts into 4 ohms is your Ayre?
What do you think of Bryston seperates
BP17 pre & 2.5 amp

Fishing716,
It really isn't a matter of how many watts an amp is at 4 ohms. 50 watts is capable of decent volume levels with synchrony one's... (88 to 90db sens)I'd probably want 100 minimum.
The problem is what happens to an amp trying to drive a 4 ohm load... The better an amps power supply is the closer that amp comes to doubling its power from 8 ohms to 4 ohms, that is the reason for the wattage recommendations. A good power supply sounds better and your amp won't crap on itself trying to drive your PSB's.
