I just saw this and can offer my experience and a really great sounding receiver. I have the had the Ht3's for a good while and used an Arcam AVR 600 receiver to power them. I then, because of an outstanding price point, got a Halo A51. While the use of the Arcam as a pre-pro. with the Halo was an upgrade, the AVR as a single box solution was excellent in my application-large room.
Now, I have upgraditis again and am looking at the Lex MP-20, which hopefully is going to be here in 6 months. I alos have an old Meridian 861 V2 and some DSP 6000's lying around that I may temporize with until the Lex surfaces.
Finally, my Arcam had some technical issues and my dealer just this week sent me a, New In Box replacement, which is still in the sealed box. I am selling that piece, but haven't posted it anywhere yet. At any rate, it is a great HT3 combo.
Thank you very much
