I discount it because it isn't physically possible, given what he's
said. If he prefers the LP to an accurate CDR of the LP, then that
preference is based on something other than the *sound* of them,
because the sound of the two will be pretty much identical.


It should be. There could be ways to screw that up, of course.
Or even a simple thing like, the output level of the playback CDP being
different enough from that of the phono stage, to produce an audible
level difference (whcih can easily 'translate' into a report of 'quality'
difference).
Level matching would be a must for a fair comparison...as would
doing the comparison 'blind', which would be tough since it
would require time-synching.

Tried again today and recorded LP to CD, playback level matched and I
still
continue to prefer the LP to the CD copy, no doubt it's an illusion for
whatever reason.
However I accept illusionary as no double blind tests were involved in my
choice of my equipment, just my ears after a period of home trial.
I accepted this as with my choice of cables. I still prefer to this day
the
unmanageable and generally unsightly Cogan-Hall as I believe they sound
much
better than other cables I've heard the system though I'm sure double
blind
tests would show otherwise. I accept the illusion though scientifically I
would really prefer to know the specific reason why this happens atall.


For what it's worth, I don't think computer sound cards do a very good job
at
this (unless they are VERY expensive professional cards from the likes of
Apogee, and the like)


Actually, many modern computer sounds cards , and certainly those of the
M-audio Delta class,
do a *very* good job at this. I use an M-Audio 2496 myself for LP transfers.

I've always had better results (sonically) from CDs
made on my TASCAM CD-RW700 stand-alone CD recorder.


But your evaluation probably suffered from the same methodologiccal flaw that


the Mike
acknowledges in his. I.e., it wasn't done double blind. And that's
imporatant because there's
no objective reason to expect a REAL sonic difference between recording from
LP on a
Delta 2496 and your standalone Tascam, assuming matched levels and a
non-pathological
computer environment for the M-audio card.


Computers tend to be noisy environments with all manner of high frequency
square-waves and general hash flowing around and radiating from them. While
many sound card vendors are careful to provide as much common-mode protection
as possible, the amount of shielding needed to keep this garbage out of the
incoming audio is generally only available in very expensive cards. Try this.
using a shorting plug on the input, try making a CD on your computer of
NOTHING and then play it back on your stereo system. You'll have to turn the
volume up, of course, but you will hear what I'm talking about. Now, use a
good, stand-alone recorder like the earlier mentioned TASCAM and make a
recording on it from the similarly shorted analog inputs and listen to it. It
will likely be pretty close to dead quiet.
