On YouTube, there is a channel named: Jay's Audio Lab. He did extensive testing with the 900 series amps and the preamp; I think he also had the new 10 series in his listening room, but my memory is fuzzy on this. Google it or go to YouTube and search his channel. He does a wonderful job getting the equipment, hooking up some of the very best cords and cables to it, and then playing them along with comparing it to other brands.
