BIG UPGRADE from B&W 685 to what?
Current setup is B&W 685 fronts, HTM62 centre, 684 rears and Rel T2 sub, wuth a Marantz 5007 av amp. I recently moved house and had an upgrade in mind so got some pretty decent speaker cables - QED Revelation. I've had stereo amps and listened to CD's/FLAC audio in the past but now i'm just looking for an easy time so my primary source is music from spotify (in extreme quality mode) streamed via airplay. I do use speakers a lot for home theatre too.
Question is, where do I go next? I could afford something like the CM10's and heard they are awesome so that appeals, but what I couldnt afford to do is to upgrade the centre or amp. So if i got some CM10's to use as fronts, could my amp adequately drive them? And would there be much value having a sub? Would the Rel T2 be good enough to keep up or would I be best just leaving the bass to the CM10's? I have neighbours either side so always play bass as low as possible anyway.
If the CM10's would require a new amp/sub, does anyone have other suggestions to complement my setup ? Would prefer flootstanders ideally
