I'm debating on buying a nice used Pre/Pro for my ht. I recently bought new Paradigm Studio 20's for my mains and I'm going to be replacing my very old HK receiver. I've been thinking about a nice B&K Ref 30 or 20, or possibly an AVR202 (I know it's a receiver though). I'm not sure about other brands. I'd like to stay under $900 and want DD and DTS at least. I'm going to be using my system for about 60%HT and 40%Music. So, any ideas?????
