Tgrisham I agree that they need to implement stiffer power supplies. Heck, to be honest every company out there including most exotic makers should invest in stiffer power supplies. Yes, I know it will increase the price of the product but a properly designed power supply will not only make that unit quieter but should actually make it produce a better soundstage too. To add to that it will make the product more reliable as well. You wonder why so many tube amps from the 50's and 60's are still on the market and still playing sounds. That's only part of the reason. IMO they used sound enginering in their power supplies then. Even though parts are superior today compared to 40+ years ago those parts still lasted over 40 and in some cases 50 plus years and still running.
Look at the Dynaco ST 70, Marantz 8B, McIntosh 275, 225, and the Eico amps. Don't forget the many other brands out there like Western Electric and Altec. If you are ever in the Destin, Fl or Pensacola, FL area look up Tom Tutay in the phone book. You will be surprised whatgood power supply design will do for the sound. Better yet Check out
