THD for starters. It is based upon an average of readings using steady state test tones. Instantaneous distortion is masked. In case you don't understand otherwise, music is a wee bit more complex than steady state tones. The Crown IC-150 preamp was the poster child for negative feedback gone amok leading to egregious amounts of TIM/SID. That is why high frequency reproduction with that turkey sounds like fingernails on a chaulkboard. Yet it had something like 0.005 THD. Totally useless.

WHEN ARE YOU GOING TO FIND OUT ABOUT SUCH THINGS? TEST TONES ARE NOT "STEADY STATE" BUT ARE CONTINUOUSLY VARYING (AT UP TO 20 KHZ). DUH! YOU ARE MAKING UP PHRASES (ACTUALLY BORROWING THEM FROM NON-TECHNICAL MAGAZIINES). PERHAPS YOU SHOULD FIND OUT THAT DYNAMIC DISTORTION IS PROVEN TO SHOW UP IN THD MEASUREMENTS AT HIGH FREQUENCIES. EXACTLY HOW MUCH TIM/SID IS EGREGIOUS? EVEN CHEAP AMPS HAVE AMOUNTS BELOW THE THESHOLD OF HUMANS TO DETECT. IT IS YOUR COMMENTS ARE TOTALLY USELESS UNLESS YOU FIND OUT THE REAL FACTS.

You know nothing of my experience. I haven't been to an audio salon in years. I base my comments on direct experience to some very nice equipment. If you want to pick on a magazine and it's staff, then you will need to pick on The Absolute Sound. I have known John Cooledge and Harry Pearson for over twenty five years. You really have no idea what HP's current system sounds like vs. live music. Which is the way of engineers who spout theory with zero actual exposure about the components to which I refer.

OH GEE, EXCUSE ME, I THOUGHT THE ABSOLUTE SOUND WAS A HIGH-END SUBJECTIVIST MAGAZINE WRITTEN BY NON-TECHNICAL PEOPLE WHO DO NOT FOLLOW (OR EVEN BELIEVE IN) SCIENTIFIC METHOD. ....HEY, MAYBE MY ASSUMPTIONS ARE NOT THAT FAR OFF?

I already gave you one irrelevant one. It's your turn to come up with one that does correlate to real world musical reproduction.

THD AND FREQUENCY RESPONSE OF THE ELECTRICAL SIGNAL TELL THE WHOLE STORY FOR ELECTRONICS (PROVIDED MEASUREMENTS ARE MADE AT ENOUGHT DATA POINTS, I.E., FREQUENCIES, POWER LEVELS, AND LOADS. THERE ISN'T ANYTHING ELSE FROM A PHYSICS/ELECTRONICS PERSPECTIVE.
REPEAT: DYNAMIC DISTORTION IS PROVEN TO BE ENCORPORATED IN THD MEASUREMENTS AT HIGH FREQUENCIES. AUDIO ELECTRICAL SIGNALS ARE MERELY COMBINATIONS OF PURE TONES YOU CALL "STEADY STATE".

I ACCEPT THAT YOU WILL NOT LISTEN TO ME AND HAVE ASKED YOU TO FIND AN EXPERT YOU TRUST. YOU ARE RELYING TOO MUCH ON YOUR EXPERIENCES AND THE STATEMENTS OF CULTISTS SUCH AS THE PEOPLE YOU MENTION.

I take your response to be that high end amps have lower dynamic distortion and that this distortion is audible at the level found in typical, non high end, amps. I disagree on all counts, but at least you are saying something other than your "experiences".
