Integrated AMplifier to Pair with Dynaudio Focus 1

I would consider the Quad 909 with a 99 preamp. $1000 might be a little optimistic for a used Quad pair, but if you can extend your budget($200?)you will have an amp on another level.

I have owned a few different integrateds lately (NAD C-350, Music Hall Mambo, Peachtree Nova), and I am currently running Dynaudio Contour 1.3s with an NAD C-372. The NAD just sounds better than the others. I was disappointed with the Mambo and the Nova, they both had a beautiful build quality but no warmth or dynamics to the sound. I know that tone controls are frowned upon by some, but I doubt I'll ever buy an amp without them again. Besides, all recordings are different, tone controls easily compensate for this. My advice: go for a pre-owned NAD integrated with some power. My C-350 didn't have the testicular fortitude to run the dyns properly.
GOOD LUCK!
