Well, not strictly true. As there is no Cyclic Redundancy Check
incorporated in audio CDs, there is always the possibility of rare,
infrequent errors. Another experiment to prove the point - take a CD
(preferably not your favourite) and drill a *small* hole in it. Now play
it. It should work just fine, you would not hear any problem despite
obvious errors. I suspect the designers reasoning behind this is that, if
CRC was employed, a great many CDs would be unusable with the slightest
scratch. CDs need to be treated with a great deal of respect. Keep them
clean and scratch/mark free and you will have very few, if any, errors.

So you don't understand CIRC.

Correct. That may be why I have not mentioned it!!!
I am talking about CRC - Cyclic Redundancy Check.
CRC is employed on data files. It is a check sum if you like. It ensures
that data retrieved from CDs or harddisks is 100% accurate. If a sector read
produces an incorrect CRC then it is read again. Multiple attempts will be
made before the source is considered unreadable. This is *not* employed on
audio CDs - the data is simply streamed - good or bad.
Try the 'hole' experiment and it should become clear to you. You may also
like to try it on a data CD to illustrate the point - ruined disc.


No need to do this. We know it is not a clone or anywhere close. It has
been butchered by the RIAA filter in an attempt to make up for the
inability of a mechanical system.

The RIAA filter is reversible, as is done in any phono preamp,
and is therefore not butchery. What is your point?

If it isn't broken, why fix it? My point, hopefully, is crystal.

Look, if you enjoy the product that vinyl delivers then fine. How many times
do I have to say it? My 'problem' is that I will only be satisfied when I
get the highest fidelity that technology will allow. It would be great and I
would be 100% in your camp if vinyl and a mechanical retrieval system
achieved that. It doesn't, it can't and it never could. That should be
obvious to all. However, if vinyl gives you what you are looking for then
brilliant. Honestly, fill your boots! I would not try and turn you from it.
However, please don't tell me that it will give me what I am looking for. I
want High Fidelity which cannot be attained through mechanical means.
