Depends on the level of your purchase. low end equipment is low end. All of it. For receivers, Id stick with NAD or another A/B class receiver, say an Outlaw system, or go high end. As far as I know,there are no Rotel receivers these days. Note: Appliance manufacturers rarely make very good receivers, Just OK for the money stuff. As for class D, I'd let someone else pay for the R&D and wait until it is perfected (if ever), The base electronics for Class D are super cheap to manufacture, so I certainly would not pay Class A/B prices for them, ever. Yamaha, Hardon Kardon and Pioneer are Tweedle Dum and Tweedle Dee, at any given price point, about the same. For the rest, you are mostly looking at high end, mostly separate component level equipment, which is a different tree in the forest from receivers. Historically, Harmon Kardon equipment tended to have a mellower, less treble laden sound than Japanese equipment. Shrug, its not like you are specifying a particular model of equipment here, or a list to track down.
