1. I do't I put in a pre amp with a HT bypass. This way you get the best of both worlds a processor whenyou need it and 2 channel when you don't.
2. I have a D2V2 I do not use ot for 2 ch I think it is ok sounding but not nearly as good as just going through my asethix clyspo pre amp. What is better is a whole nother story and based on what you like to hear.
3 I doubt it. Although I really perfer monoblocks and keeping the speaker cables as short as possible. That will make the bigest difference. But again depends what you think sounds good.
