I'm more familiar with the Diamond series and those I heard were good for the money, outstanding midrange.

Any stereo integrated amplifier should be able to handle a 6 Ohm nominal impedance. A Jolida JD1501A would be nice for $675, if you could figure out who actually owns right to the company. The Cambridge Audio 740A is $879 on sale. If you were looking to spend less perhaps a Harmon Kardon HK3490 for $280 would do.

There are quite a few in that price range on AudiogoN.

Music Hall A 25.2 $250
Cambridge Audio 640A V.2 $295
NAD C325 BEE $295
NAD C320 BEE $220
Yamaha A-S500 $275
Cambridge Audio 540A $250

None are 100 wpc but in a bedroom with 87dB sensitivity speakers 50 wpc should be adequate.

Bi-wiring has limited utility for most applications. Just use a single run of appropriate gauge quality speaker wire.
