okay, here we go again...

Iasi- Have you considered the option of getting a CD player with volume control and running it direct to the amplfier? Though I prefer having a great pre-amp in my system, this approach might work well for you and allow the consideration of a Cary V12 amplfier. It's just an idea. Good luck.

I have Acoustat electrostats in my second system , a notoriously tough load for amplifiers. I have been using a Musicial Fidelity A300 Intergrated for over a year with no problems at all. It seems to control the Acoustats with no loss of dynamics or bass response. Good luck.

You'll need serious driving (current, etc) abilities for the speakers; three products that come to mind are Symphonic Line rg10 (i heard this recently), YBA Passion integre, MAYBE the Pathos integrated (tube hybrid).I liked the sonic qualities of all three. (Doesn't Innersound offer an integrated?)
I've heard them drive difficult loads but NOT the Isis, so please check them out if interested. Cheers

that's the problem...i want to move away from pre/power amp combination that i have right now...i'm usually listening to about 90-95 dbl the loudest passages...my room is 23X18X8...and i need inputs for only one source, the cd player...

Iasi- It would help if you included a little info such as: how many sources does the integrated need to accommodate (if CD only, what player will you use?), the size room and typical spl level at which you like to listen? Depending on the above answers, would a separate pre and power amp be a consideration if kept at your desired budget? You'll need to give a little bit more info, if the responses will have any hope of value.
