Hi I am looking to buy a processor, but am confused by what is available. It will be used with a Rotel power amp and M&K speakers, almost exclusively to watch DVD's with occasional Sky TV. CD's may be played, but only once in a blue moon. I would like the option of DD EX and DTS ES although I only have amp and speakers for 5.1 at the moment. Tag's and Lexicon's have been suggested to me, but they seem to offer more than I would use and I could only afford second hand. Should I go for one of these, purely for quality, or would something like a Rotel 1066 be sufficient?
