I don't avoid that anyone avoid blind listening tests.

However, when you've got two amps, I suggest switching them to see
which one is preferred.


Or, if you have a PC with a good sound card and monitoring system,
you can do power-amp related DBTs by downloading files from
http://www.pcabx.com/product/amplifiers/index.htm . You can
definitely hear differences in power amps using files from these
pages. If you can't you probably need to upgrade your listening
environment or have your ears checked.


Your results are of interest, but the combination of a particular
amplifier with a particular speaker are what concern the audiophile.


There are no *results* posted at
http://www.pcabx.com/product/amplifiers/index.htm . The results are
formed in people's minds after they listen to and carefully compare
the audio files.

Nevertheless, I can't argue against the experience you provide, even
though it's useless for the purpose of choosing the combination.


The tragic flaw in trying to match amplifiers and speakers is that
the audible flaws in speakers and rooms are like a California wild
fire, and the audible variations among good amplifiers are like
garden hoses in comparison. If you want speaker-sized audible
differences you need some kind of equalizer, not a merry-go-round
full of power amps.


Three Bryston amps and three competitive amps are listed there for
people's listening pleasure. Power amp tests are tough, so I
recommend that people who are not familiar with the PCABX process
start with the home page at http://www.pcabx.com/index.htm .


An interesting education, which should force the conclusion that one
should test the intended amplifier/speaker combination together.


Just guessing here Bob, but I'll guess you ain't downloaded and
listened to
squat from http://www.pcabx.com/product/amplifiers/index.htm .


The website has no use to me. A large variety of equipment becomes
available to me either as a free loan or at very low prices. Since I
seek only to optimize my own personal experience, your recorded
samples are useless.


Transparent attempt to deceptively avoid the level-matched, time-synched,
bias-controlled test issue.

Nevertheless, since most audiophiles do not have access to the wide
range of equipment available to me, I suggest they listen to Arny's
samples, and then forget about them.


Bob, it's quite clear that you're afraid of finding out that you've got
flesh-and-blood ears like the rest of us.

But thanks for confirming my speculation about your continued desire to
remain unnecessarily ignorant.

A lot of old hands have benefited from the PCABX experience, but there are a
lot of old dinosaurs who are still resisting it.
