New power amp for Quad 11Ls


My current setup:

Music Hall cd25.2
Music Hall a25.2
Quad 11L
Onkyo T-9 tuner
Audioquest Alpha-Snake interconnects
No-name 12-gauge speaker wire

I'm looking to upgrade and am thinking that I could get more out of my system by adding a power amp (I'd use the MH a25.2 as a preamp for the time being). So I'm wondering whether something like a PS Audio A100 would be a good match for my Quad 11Ls (which I really like). Any other ideas around $1000?

I'm working on new cables, too ...

Thanks.

I should clarify, too. The room is relatively large, but the listening position is roughly what Frihed90 described (sitting 10 feet away with the speakers 8 feet apart and the speakers 3 feet out from the wall).

The idea behind my question was whether, given the Quad 11L's 86dB sensitivity, moving from 50 wpc to 100 wpc would get more out of them. Some posts on this thread and others suggest that it would. But now I wonder whether I'm really just looking for reasons to buy a new amp .... Nothing wrong with that, I suppose, but it's not what I intended.

Well, I went ahead with the PS Audio Trio A100. I'm glad I did. I got a good enough deal that I figured I couldn't lose money, and I like what I'm hearing. Improved clarity, detail, and transparency. More bass definition as well; this is the one area where the change has made the limitations of my little speakers clear.

All the feedback was helpful, thanks, and so was this thread:
