I'm in your same situation, and I decided to go with a Plinius 8200 integrated. It has a HT passthrough for movies, and by bypassing the pre section of your HK receiver for 2 channel, you'll get much better music. I bought it on Audiogon and haven't received it yet, so I can't tell you exactly how it sounds, but if you read reviews here, on AudioAsylum, and on AudioReview, I'm sure you'll see it's very highly recommended. I went with the mkii, but the mki can be had for as low as $1200 used - currently here on Audiogon (both are $3000 new).
Good luck.
