How many of you guys use a HT processor ?

I was thinking about using a home theater processor as a 2 channel pre amp and was wondering how many of you use this set up with good results. I understand that it would be overkill specially using only digital as the only playback source, but I would think that the processor with it's built in DAC would save on space and ICs. My two top candidates would be Theta or EAD. I listen to all types of music but value acoustical (guitar) and vocals highly. I would appreciate your opinion.
