Dynamics at lower volumes?

1) Horns
2) Revel Ultima Salon 2's

Yes!! a hard answer to find.
I listen exclusively at lower volumes.
i bought a pair og Maggie 3.6 (which so many say you have to play LOUD to sound good) the thing is Maggies have a good low level playing ability.
With the Bryston stuff i have i am happy. I have a Audio Research pre (the SP-15) problem with that pre is it does rally sound better at 3/4 volume control on up. ctually using a passive pre vol to LOWER the level going into the AR made everything so much more alive at lower SPLs.
The word is the PRIME speaker for lower SPL playing Quads.

Elizabeth. You are gain matching. Try using the passive after the preamp instead of before.

As with certain tube designs, some Class A designs sound particularly good at lower level. I think it would maybe follow that more efficient speakers are probably better at low levels than greatly inefficient speakers, as they need less juice to open up, but I'll defer to the more technically inclined audiogoners to confirm or disconfirm that.
