TBT, I am a bit hardware oriented, and I base that statement on reading the

As I am not privy to what chip is on audio card x, at any one week n, I
think to actually name names & model numbers (something else I have learned
to miss-trust, dealing with ATI's video cards, which can get changed at
about the same rate we change underwear, can be exceptionally educational)
is generally pretty frustrating. So other than the card I presently use, I
won't give any name, rank or serial numbers. Why? Ears are at least as
variable as eyeballs. My eyes for instance, have had glass in front of
them for the last 71 years. My color vision OTOH, is very very good.

I don't claim to have ears that matched Larry Klien's when he was doing all
his pundrity in the audiofile rags 30 years ago, but at my age, I think
they are generally not lying to me when I listen to something for several
hours, with a rather eclectic mix of music, and do not get tired of it.
Toss in a bit of digital aliasing, a bit of monotonicity errors, then add a
3rd order intercept of 40db or less for the two tone so the net total
distortion approaches .5%, and these old ears are screaming for some
silence in 5 to 10 minutes.

However, I have been amazed at the number of folks out there who can listen
to 5% THD and a 20 db intercept on a two tone signal, with a bit of
aliasing thrown in, and absolutely cannot hear it, the difference to them
is a total shrug. It boggles my mind to think of what they are missing.

OTOH, given the class of folks who seem to inhabit this list, I think there
are some altogether decent ears here. Your tastes in music might assault
me, and mine would yours I'm equally sure, but the technical ability I hear
in most of the samples posted so far is far better done than the average
garage band console can pass. You are being 'picky' and for that I salute
you all. Technically, the state of the art in making music seems to
continually improve. And its people like you that are part of that driving
force behind that.

Thanks for reading this far. I'll get me coat now.

Cheers, Gene
