All new:
Magnepan MMG ($600)
Outlaw Audio Model 2200 monoblocks ($700) <- these are on sale in pairs sometimes, so you could get them less than that. I believe Barry Diament uses them as his reference amps even with his Maggie 3.7
Prometheus Audio TVC preamp ($390)
Leaves you with around $700 for source and cables, once you pay for shipping on the Maggies. Go with whatever floats your boat here within budget. I have owned the above three components at one point.
