Burned CDs can sound better than the original?


I recently heard a rumor that some CD burners can actually produce a CD copy that sounds slighlty better than the original. As an Electrical Enginner, I was very skeptical about this claim, so I called some of my reviewer friends, along with some other "well informed" audiophiles, to verify this crazy claim. Guess what, they all said : "With some particilar burners, the copies do sound slightly better!" I did some investigation to why, after all, how can the copy sound better than the original? So far I've heard everything from "burned CD's are easier to read", to "the jitter is reduced during the buring process". Has anyone else experienced this unbeleivable situation? I'm also interested in other possible explanations to how this slight sonic improvement could be happening.

Hi Bluesman -

Nero Burning ROM is a software package - I think, the best consumer level ($50.00 or so) out there. The company that makes it is called "Ahead". Can be found - and downloaded from the WEB. See their site for compatibility. The "Audio" wizard is simply the icon to use from the series of options they give you as icons withing these software packages. i.e. click the "Create Audio CD" icon, etc. Sorry for the confusion, I stated this because in some pkgs, you can duplicate a CD as bit for bit data, but you won't get any jitter reduction, but instead be transferring all the original garbage as bit for bit copies instead of getting any reclocking.

Regarding other software - I did, however, get very good results from the older Adaptec Easy CD creator v3.5 - before ROXIO - using the SCSI chain. I can't comment on the ROXIO version).

But Nero Burning ROM is FASTER and keeps up with a fast burner. I can assemble complilations in 15 minutes on my hard disk and burn them in 5 mins with my 12/10/32 SCSI drive.

More on CD burning:

It seems that most of us want two functions:

1. Transfer of music LP, etc to the CD medium - we dream about high quality copies. Stereo component player/burners seem to do this the best.

2. CD to CD copying - compilations, or just reburning to get better sound ( I found with my old CD ref player, if it would not read, or skip on the commercial CD, I could burn a copy of the CD and it would both sound better and actually play. Computer burners/software seem to excel at this.

So, it's important, if you want to do both of the above and if you want all the convenience in one component - either a stereo system component player/burner, or at your PC - sit down and make out a budget at the quality level you can afford. (PC = soundcard, SCSI burner and/or reader)

For most of us that don't have $500.00 computer sound cards, not to mention the inconvenience of trying to record into your noisy PC, a stereo component CD-R/CD-RW such as Marantz, etc., is better at copying various sources to a CD than it actually is at CD to CD transfer (it may sound same, but won't necessarily re-clock and improve a cd over the orig. - many recent reviews of these player recorders seem to confirm this).

And the PC CD chain, for me, at least, almost always creates an improved copy going CD to CD if the right SCSI component and software chain is used - markedly so, but even with a soundblaster "Live" card, a PC's copying capabilities from various sources - LP, etc then to CD is limited and not very appealing for the effort.

So for now, we can always solve both issues for the highest quality by adding more components we're not sure we really want!!! Spend Spend Spend - the audiophile quagmire until some genius puts it all in one easy package that's affordable (I'm in the market for the Marantz DR-17 to accomplish all my goals, but that ain't exactly what i consider affordable).

Regarding item #2 of my previous post - regarding imperfect pit spiral/alignment on factory CDs. Note: this covers either the case where the hole of the plactic cd is off-center, though the spiral is perfect, or the case where the cd is centered correctly, but the spiral is laid down poorly.

If you want to know how much your cd player is working overtime: I just read an article in Stereophile - Sept 2001 - ref. pg79-80, where Jonathan Scull reviews a $25,000.00 CD transport called the 47 Labs 4704 PiTracer, and, as an aside, is able to note the incredible work the transport mechanism is going through to simply read the cd!

I can imagine that a degradation in sound happens when most cd players mechanically track - I'd love to see him compare a good CD-R's tracking to a factory CD's on this machine!!

In my systems, a properly reclocked/burned cd can equal the effects of a major component upgrade.

About 8 or so years ago, I did a test of CD player / Transports and their ability to accurately retrieve what was on the disk. At the time I hadd access to a $40K real-time analyzer and I was trying to prove that all transports were the same and that transport tweaks were useless. Boy was wrong on both occasions. First the CD Red Book standard is not very robust. Second Most CDs don't even meet the minimum standard. Third Even the best transports had read errors, 25 - 40% of the samples on premium transports to more than 95% on mass produced models. I nver thought that the errors could be due to poor track path, but that makes good sense. I'm going to get a new CD burner and Software and do a comparison of burned CDs with stamped ones.
Blues_Man - that's really interesting - I've wanted to hear somebody's experience performing the tests you describe and would be interested in any more detail you might have. A similar test that would be interesting to perform would be somehow analyzing what the transport in a computer CD drive is doing - how many re-reads does it actually have to perform to get the bytes exactly right. It would be interesting to see a histogram of how many times a given track was read - you'd expect a the most at once and a reduced number as the attempts went up. Then it would be interesting to know how many of those read errors could be corrected by the checksums, etc.

I have done comparisons of CDs copied on a computer CD burner and get perfect copies (when it works - occassionally the process fails and spits out the wasted CDR). It's pretty easy to do with the program Audiograbber, available for free. -Kirk
