CDs have a clarity to the sound that beats even the best LPs.

In most I would agree. Some CDs are remarkably better, it's amazing what
you can hear on some compared to the vinyl equivalent. For me tho' clarity
alone does not make CD a prefered format.

As much as I play CDs now I still find vinyl very alluring & involving. A
good recording can have me almost mesmerized.



OK, that's an interesting statement - what do you think of these
near-identical clips (one CD, the other vinyl)?

Do you have a clear preference?

Miles A is a lot cleaner, much lower distortion on the highs, so I assume it
to be the CD. Sounds much nicer to me.Miles B is also a fair bit louder and
sounds compressed in comparison with A. Interestingly, the frequency
spectrum of A cuts off very rapidly at 16k whilst B goes on to 21k. I assume
therefore that A is CD, and the relatively limited bandwidth is a function
of the original tapes, whilt B is vinyl, and the very top is just noise.

You are right - A is the CD. (I 'normalised' both those clips to -16 dB and
that's what comes out - Gawd knows what's going on in the software!) Also,
the vinyl clip was my first attempt at recording to this (Vista) laptop and
it was a nightmare!

The CD clip exhibits the 'clarity' (lack of noise floor) that is often
associated with CD, but it simply sounds *shouty* to me and the percussion
is brittle when compared with the vinyl. Disregarding *measurements* for
this purpose and using only my ears, once again, I prefer the vinyl (what
new?) by, er, *miles*!! (Oops :-)

Ya pays yer money....

(Except in this case I did for *both* the CD and LP....!! ;-)

I think you'll find they were normalised to -1dBFS, at least, that's what my
software shows.


The CD clip exhibits the 'clarity' (lack of noise floor) that is often
associated with CD, but it simply sounds *shouty* to me and the percussion
is brittle when compared with the vinyl. Disregarding *measurements* for
this purpose and using only my ears, once again, I prefer the vinyl (what

Strange isn't it, it's B that sounds "shouty" to me, especially the
roughness with highs.

Indeed.

The bass is also somewhat recessed on the CD version which is what makes it
'shouty' to me, but I've trimmed the clips down:

http://www.apah69.dsl.pipex.com/show/SmallMilesB.mp3


.....to enable more direct comparisons to be made and, if anything, the CD is
more shouty than ever and completely lacking in 'texture' - by comparison to
the vinyl, which is why I consider CD to be less *natural* and certainly
less 'listenable'!

(I guess one man's 'texture' is another man's *noise*....?? :-)

Exactly the other way round for me! A is clean, B is coloured (shouty isn't
a bad way of describing it) I suppose your texture is my coloration. By the
way, what cartridge did you use for the vinyl? I would guess an AT95 or
similar.

The 'something added vs. something lacking' dichotomy again? :-)

A Goldring Electro II+ which is a high output (2.5 mV) MC with a van den Hul
I stylus. (So, not really!! :-)

(That's after having found a busted wire in the connectors on my other deck,
which was the one I was going to use - and which you've reminded me needs
sorting!)
