Blue Circle CS Integrated with ATC SCM7 Speakers

The only hesitation I'd have with the ATC SCM7 is that it has a relatively low sensitivity (84db), and while the CS may sound good with it, there are probably better matches out there if you haven't committed to the SCM7. You might want to consider something like the Von Schweikert VR-1; or slightly more expensive, the Aurum Cantus Leisure 2SE. The Green Mountain Europa might also be a decent choice if your room is small and you're not looking for big volume (it's 88db, but it's also 4ohm, so the current demand is pretty high)...
