Yes to DSPs, but limit them to a useful set. I never use any of the DSPs on my Yamaha receiver. The gimmicky processing and added reverb just don't sound realistic. The only DSPs that I would be interested in are 5/7 channel stereo with a derived center, similar to Lexicon's Party mode, and a DSP mode to provide some derived ambience from old mono movies. I'm planning to replace the Yamaha with separates in the near future. Features such as these may make the decision easier
