Also this system combo has an excellent top end and detailed bass response.I was able to buy a used Audio Research D-400 MKII amp on ebay in near mint condition for just $2270 delivered. I have seen ARC D-400 MKII's listed used on a few web sites in the $3000-$4000 range. If you go with this amp make sure you acquire the D-400MKII and not the D-400.

Audio Research D400 Solid State power amp. 400 WPC in to 4 ohms. 60 amp peak at 1 ohm. Quite a power house. I've owned the amp for 20 years but with high efficiency speakers I no longer need anything near this powerful.

and micro) are two strong suits of this amp. Before the D400mkII I was running two ARC D240mkII SS amps (120wpc/8ohm, 240wpc/4ohm). These two amps share very similar circuit. The D200/D300 are slightly different circuit and frankly a step below the D240/D400. The D130 is more similar to the D200/D300 while the 100.2 circuit is more similar to the D240/D400.
