I'm a big fan of the HTP-1 and that is stilltop of my list right now for dream components.
All of these have issues, but the HTP-1 is pretty much fully functional and is just waiting on the Bass Management from Dirac, and maybe a few other very minor things.
The AVS HTP-1 Owners Thread is very informative, and the nitpicking the cats over there get into is testament to the amazing job ATI and Monoprice are doing with that Pre-Pro.
