Are copied CDs lower quality?

Hi, I was just wondering if a copied CD sounds worse than a original CD? I tend to backup all my cd's by coping them however if they loose quality perhaps there is a better way for me to do this?

Thanks.

Nick interesting reading for you to peruse, I notice no difference with CDR to originals, and that is not just normal redbook 16/44.1 but also 20/44.1 copied WAVs burned onto CDR. The thread belows get quite interesting at about pages 7-9, I even posted off a CDR for someone to blind test and its worth reading those posts.

Won't I buy a new cd ever?

I have though noticed on some fast speed burns, ie 4X+ that I create quite a few coasters, that is CDRs that jump etc etc, I would say then that slower burn speeds create less problems ie error correction detection on some optical laser assemblies. I always burn at 1X or 2X, at these speeds its impossible to tell the difference to the original. Above that and I have some older CDPs that struggle with the “quality” of the CD. Ie skipping etc, when the error correction is too much for the CDP to handle.

Anyone (IMHO) saying different should try some blind a/b tests with the original CD (superior) and copy (inferior) and be able to identify each, I could not at all when I tried. And I don’t know of any properly conducted tests in the blind domain that have tried it TBH.

As soon as he says this......."we can now consistently make a copied CD sound spectacularly better than the original." You know he's talking out of his arse!!

Thanks for the replies - will get reading! I tend to burn at 2x when copying my cd's and 40x for anything else (data etc).

By the way CJ my Dad is using the Tag dac at the moment while I sort out my system - he loves it so might have some trouble getting it back! He isn't an audiophile by any means either.

Using an external DAC will give better improvements compared to using different blank CD's IMHO.

There will always be a small amount of difference between an original and a copy, but it's never enough to be noticeable on any scale, with the exception of burning coasters of course - but generally speaking a copied cd should be just as good as the original, it's only when you start making copies of copies that at some point down the line the degradation becomes noticeable

An un-compressed WAV file burnt to CDR and thus is an Exact Copy of the original. Or am I missing something here.

Nick tell your dad he has fine taste, whats the rest of the system he is using it in, please say a nice stereo amplifier with decent speakers.

Aye that 'twer I and the results were as conclusive as possible using a high quality HiFi system with very revealing speakers. Could'nt tell the difference and ended up buying two Cds by one of the artists on the compilation.

ok he went overboard there :P

doesn't mean you can't try it out yourself, and possibly benefit from the article i.e make at least a few back-up copies which are as good as the original

I read the article, downloaded EAC and tried it and yes the copies I've made are better than what I was getting, but for playing in the car etc I'm not that bothered as they get slung around.

And although I too think his talking crap about the copy being better than the original. I think what his trying to say is that in theory if EAC copied a disc and made a better job of it with multiple reads correcting the errors that a CD player could never do while playng a disc, then that image burnt to a CD could be read by a CD player with less errors than the original, so in theory because the CD player has to work less hard it should sound better. But can any copy ever be better than what it was copied from. I think it's all speculation.

The short answer is NO quality loss at all as long as you do a DIRECT copy from one CD to A CD-R you will not be able to notice any difference.
