B&K ref. 20 or Sunfire TG1

I'm struggling between the two componets. I think I have narrowed it down to these two based on my ever increasing budget, reported quality/reliability, performance and Price to features. I'm going to be using my home theater 80% of the time. I don't need component capabilities since I will run all video directly to a new Mitsubishi 55 widescreen. The only down side to the Sunfire is that it doesn't have dual zone which I need. I hear that B&K has great tech/coustomer support. Do you guys have any input or ideas. I'm trying to stay around $1000-$1700 for the pre/pro. Thanks for the input
