No one is a fool for being skeptical. Many of the claims in audioland
are quite foolish indeed.


Yet in a high resolution system, power cables and interconnects can make
a difference. Not always an improvement, but a difference. A large fat
power cable can augment an insufficient power supply in a real world
power situation. Admittedly not the right solution, but it can help.


People often make such claims. Usually on the basis of not having done any
test whose results could be assessed for reliability, nor having bothered
to ensure that the many well-known possible causes of error were dealt
with. Thus making the claim worthless.

I recently changed the IC's in a Quad 306 power amplifier (TI's to
Burr-Browns) playing through some Quad 988s. My wife (not an
audiophile), walked in the room and immediately asked what had
changed... "it sounded more alive" was her comment.


Comment much as above. It is a common experience that what we hear
'changes' from one situation to another. Afraid that simply isn't a basis
for deciding *why* a 'change' was heard. Far too many other possible causes
or reasons which your simple anecdote fails to deal with.

Or are you saying you had her repeatedly walk into the room, having
switched at random between the two types of IC? And that you carefully
arranged to always play the same music at the same volume? And that you
changed nothing else whatsover? And that she always walked in by the same
path, to the same position? etc, etc...

Slainte,

Jim
