Invest your money into a 5 channel amp (or amps). The quality of the signal on digital dolby is not as good as the compact disk. Also the standard for future DVD has not yet been decided on by the manufactures.(or, for that matter; the dvd-audio only standard is at least a year off.) The amp you buy now can be used with any future format.
More critical? Amp or Signal Processor Pre-amp
I am considering buying a 5.1 home theatre. I don't know which i should spend most of my money on;the Pre-amp signal processor or the amp to drive it. I like Mcintosh and I have Klipsch speakers. My budget is around $3k. Please Help!!! Thanking in Advance... Louis
