Amplifier suggestions

find a used pass or proceed five channel amp...
if you want to save some money and get an excellent THX multi channel amp find a parasound hca 1206 which has 6 channels at 135 wpc/8 ohms, 200/4 ohms....4 channels can be bridged for two channels giving 350 wpc...

used about 700 to 900...get one with original double packaged box as it is a bear to package....originally 2000 bucks in the mid 90s.....john curl design...try it before you spend 3 large....sell it if it does not satisfy...I suspect it will

Dynaudio and Sim Audio have always been known to have stunning synergy.

If you can go a bit above $3k, you could grab a nice used Sim Titan 5-channel (aka, HT-200-5) and build a great system around it. Cool-running, smooth and natural-sounding, with sweet mids and warm mid-bass (I miss the one I used to have!).

Please do yourself a favor and audition a Linn 5125 if you can. These can be had for under 3k new and well under 2k used, and are incredible for the price. One knocked the daylights out of the similarly priced McCormack DNA multichannel amp that I recently auditioned in my system. If you are able to borrow one to take home, you will likely also need to borrow speaker wire with BFA plugs, which is a pain (unless you use something like AudioQuest plugs already). I can think of no other downside.
