Re: Pushing you a little more :)

I have no way of knowing but if it had to take a wild guess, I'd say that if everything else was pretty much the same, the difference would most likely be due to the power supply. IMO, the most important element in any power amplifier is the power supply. No amplifier of any design can be better than its power supply. The best are very conservately designed, are line and load regulated, and have rapid recovery from overload. And BTW, almost surely have solid state rectifiers. The most important element in the power supply is the power transformer followed by the filter capacitors. That's why if I had only one specification to judge an amplifier by, I'd want to know how much it weighs. I've gotten a lot of reports from friends who told me they made substantial improvements in their old Dynaco Stereo 70s just by replacing the power supply with a much more robust one of the same bias voltages. It's discouraging to see very expensive amplifiers even though they might have modest rated power output capbilities with puny power supplies you could build yourself for a hundred dollars or less. The least a $10,000 amplifier can give you is a good power supply.
