In Reply to: I have a number of amps on hand ......... posted by three_sox on March 10, 2007 at 04:48:54:
... of those amps...I'd be prepared to put money on it that the "order of performance" shown would correlate very closely with the various amps' ability to come close to "doubling wattage into halving load" - with the Cyber monoblocks a definite winner (separate power supplies are "finestkind" in audio).
What would also make interesting reading would be a comparative set of frequency response curves (dB at frequency) to identify any potential culprits for the "psycho-acoustic loudness prize" (some amps have peaks in the midrange (usually upper mids) that tend to create a false impression of high playback levels because the human brain perceives this band more clearly than the balance.
Having compared integrated stereo amps with stereo power amps and with monoblocks - I'm convinced that the more "dynamic headroom" there is in the power supply coupled with less need for "power sharing", the better the end sound quality will be.
Interesting note: I've always found that a high quality and neutral sounding system will not sound as "loud" as one of lower sound quality and a lack of neutrality to the sound. By "loud" in this context, I mean that the sound results in me wanting to get up turn down the volume (or, in really extreme cases, leave the neighbourhood entirely...)
Oh well... it's approaching 16h00 here, so I suppose you're already in the arms of Morpheus and will only see this in the morning -
G'Day Bruce!
