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?
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.
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.
Sorry Fishing716, I really should have mentioned. If you are a rocker, or listen at relatively high volumes for long runs of time, your Rega might have a problem, but if you listen at reasonable levels for an hour or two on occasion and aren't driving the bass hard. Your Rega should work fine... I don't want to mis lead you though, other amps that have proper power supplies may or may not sound better than your Rega, depends on the amp and your listening habits.
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.
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. http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1382476029&read&3&zzlMusicland1&&
