Rega Elicit R w/PSB speakers

As in your other thread, advice will be the same; look for an amp that doubles it's power from it's 8 ohm rating to 4 ohms. (or close to double)
The impedance curve of the One's shows how hard they are to drive; The amp has to be able to drive the spkr below 4 ohms.

Rega Elicit...
105 Watts per channel into 8Ω
162 Watts per channel into 4Ω
Looks too low IMO. But the website states a Class-A driver stage, so I don't know.

Were you able to try any other amps from your dealer?

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
