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.


Actually, you missed MY point which is the same as yours. Published
specs usually don't tell the whole story and improper testing procedures
can obscure that story. People buy on published specs, features, and looks.
Very few have the facilities to do even a cursory measurement in order to
find out what the actual specs are, and whether or not the device of
interest meets those specs. And they certainly don't get access to test
the component before buying it. People have to rely on published tests
and even they often don't do stringent tests (many don't test at all.
They just listen) like measuring output power with both channels driven
to their rated output. Usually they test one channel at a time when doing
these types of tests.
