I have a 568.2 with Wilson Watt Puppy 7's, I thought that the 568.2 would be a decent preamp, but after I set it up I decided to get a good analog preamp w/ a home theater bypass. That feature allows you to just pass through the prosessor info with a unity gain(volume controled by prosessor) when in that mode or when just listning to 2ch use only the analog preamp.
