Nah. I have two amps here one is a Krell i300 with 150
Watts/Channel, but it has only one power supply with a
single toroid transformer. The other is a Harman-Karden
HK-990, which also has 150 Watts/channel. But the H-K
has TWO huge Toroids (both about 30% larger than the
Krell) and totally separate power supplies for each channel.
The H-K just sounds better, especially at high volumes.


You CLEARLY missed the point: your citations of "150 Watts/channel"
are most assuredly NOT measured performance but the manufacturers
specification. You have presented NO evidence to show that, in fact,
they do not measure dramatically different under the conditions
you're claiming.

Specs are not measurements.
