Pressed commercial CDs can sound significantly different from one another,
Ans any burnt copies of these will have more error corrections that have to be done. Because of what you see and the laser has to see in the link below

OK Michael, forget about the tonal differences, with playback/burn equipment. From a retail stamped CD, burnt to a blank once or from each burn consecutively say 10 times, which has the least errors on it? The original, first gen burn, or 10th gen burn. Cheers George |
And in this instance, I agree with you that the copied cda file should not sound better
This is all I'm saying the more you read write(burn) from a CD the more errors there will be. I don't give a ratz **** about downloaded music as I have yet to hear it compete with CD on a good transport converted by a great R2R Multibit Dac All I'm interested in is PCM Cd's 16/44 and 24/96 or PCM DXD which is only by download Cheers George |
There are a myriad of reasons I’ve abandoned CDs long ago. I still have 4000 though....
I still find they are better sounding than a copy "from them" to any other format. Unless you can get hold of the original master, that has one less transfer than CD naturally. Cheers George |
Nevertheless, it doesn’t prove anything.
Again, sez you. Cheers George |
In fact, most of my DVD’s and Blu-Rays are also going the way of the CD’s -- to a HD and into storage. If you look after them, how many CD’s or DVD’s have failed you, then compare how many Hard Drives have bit the dust. Big difference to me, I’ve lost count how many H/D’s I’ve lost since 1987?, maybe the new solid state ones are better, as yet too small and expensive Yet I still have my original 1982 first CD Love over Gold and it’s still perfect and sounds magnificent as the day it was bought.

In your face and musical are just words. They certainly don’t mean the same thing to everyone. I like things to be in your face if that’s how they’re supposed to sound. I don’t like laid back sound if it’s supposed to be more present and dynamic. Read again, I didn’t say laid back sound, I said "musical" and not in your face (meaning hard/harsh to me). Fact is the odds are going negative, more you burn the more errors there will be, as the laser has difficulty reading the not so clean pit/lands of a burnt CD no matter what blank is used, even though some are better than others. Nothing is as clean as the original stamped/moulded retail cd, as the pics below show. Left moulded/stamped retail CD, pits are clean to read hopefully to be error free Middle and right burnt CD-R pits one gold one normal silver, not clean and can cause errors. https://www.iasa-web.org/sites/default/files/tc05-fig20.jpg Cheers George |
PS: the cd retail stamped vs copy burn pics above comes from Jean-Marc Fontaine just one of digital’s foremost authorities. Here is just a video conference of his which discusses the drive mechs and storage of digital https://vimeo.com/16104280Cheers George |
And yet the sound is better on the copy.
Sez you and the OP, I have never ever found this, always the original has sounded less in your face and more musical. Cheers George |
What I originally said to which your twisting, is the burnt pit/land is harder to read and will cause more error correction to happen than the original retail stamped or moulded one. As this photo shows, the difference is clear, that the original on the left will be easier to read and have less errors than both burnt middle and left.

Do your homework Geoff, if a pits/land can’t be read because of a cd burn or scratch or defect, it’s substituted by the same last readable one, it’s a 50/50 chance of being right, that is simply what error correction is.
Cheers George |
reduced jitter by burning a CD-r copy. This mainly depends on what the jitter spec is of the dac and it's interface to the transport/streamer that doing the last d to a conversion, not so much if a original or burnt copy is used. Cheers George |
Multiple generations of read/writing increases the error count of the original by quite a margin. Once a zero or one (from the previous readable pit) has been substituted for the original unreadable pit, there is no way it can be resurrected to be a readable original. There is always only a downhill slide the more times it read and written.

A lot of CD copies do sound better than the original CD. I think it has to do with error correction. Watch a CD spin in a top loader with a window. CDs are not perfectly balanced and will oscillate. I believe this can cause read errors. " I believe this can cause read errors." And play/write/replay errors Think about what you said, the errors are still there if you burn them, even more so as then there are two reads and a write with errors from all three. What I posted is correct in my last post, re the pits and the burning v stamped/moulded, there is more errors in the burnt than the stamped/moulded original retail cd, I've checked this with an error counter in a Genisis Digital Time Lens that can give error figure count Cheers George |
I’m not dreaming - these are great CD copies I think your hear an extra something to you good or bad) that error correct gives. Original retail is always best. There’s a lot more laser error correction goes on in a burnt cd compared to a stamped retail CD see the "pits" the laser has to read.
