    Burned Audio CD-Rs

    Yes U r right in that sense that higher resolution does results in more clarity n details for example for the same album which comes in a normal CD n in XRCD format, of course the XRCD will have more details n clarity. What I meant by saying that the burnt CDRs does not have "better" resolution is that the whole process of duplication does not result in additional "bits" of data being burnt into the CDRs. The "bits" r essentially the same as what the original contains. If the burnt CDRs were to contain more "bits" than the original, then I would say the softwares or hardwares that r used have "altered" the original sound by creating some other "effects" that may "colour" the original recordings. But the process/method featured in this thread is to copy exactly what the original contains n not adding more "bits" As to why the CDRs can sound "better", since both r having the same no. of "bits" of data is actually mentioned in the article. So am I right to say that your drift is that there is no increase in actual resolution, but better details and clarity (which are linked to resolution)? That was actually the question I was trying to ask, as I see that hard to comprehend. I can understand why a CD-R could sound "better", but not how there can be improved details and clarity without increased resolution. I didn't manage to finish reading the article btw, but browsed through more than half and it wasn't mentioned. It's a long read. Also I am skeptical that the duplication process is 100% accurate (even DNA replication isn't that accurate!), so colouration is a possibility even without the addition of more "bits". It's like in DNA replication, changes can occur if a base is substituted by another (one "bit" of info substituted by another "bit" of diff. content due to imperfect duplication), not necessarily only when there's insertion/deletion. I'm sure this analogy is not perfectly apt, but that's a question I have in mind. How about this analogy ? Playback the same Original CD or CD-R on the same setup except using different headphones. Why one headphone can sound "cleaner, clearer n more details heard" than other headphone ? Does it mean that a higher-end headphone can produce higher resolution thus better details ??? Same CD should have same resolution rite ??? Sometimes even different original CDs of the same album, i.e same album but different batches from the same location or same album from different pressings from different countries can also sound quite different. Post by Firefox has summarized the main essence of this topic.

    Burned Audio CD-Rs

    Excellent short article that sumarrizes the 2 main points on why CD-R can sound better than Original CD. As I am in the IT industry, when I was first told about this, I swear that this can never be ture as digital data r nothing but Os & 1s. So if the burnt CD-R contains exactly the same Os & 1s as found on the Original CD, when playback on the same setup at the same volume, how can the CD-R sound better ? Until I heard it myself n going more in-dept on this topic that I realise the logic behind. Well Done !!!

    I guess the CD-R is supposed to be a VCD ? Have U ever tried playing back on a PC before it fail to read ?

    Btw, I don't see any disc rot and my discs were properly stored. Any chance of retrieving data and burnt onto another disc or is the data permanently lost? Ah...always not too old to learn something new but I'm skeptical of how a conventional pc can create better copies than a commercial machinery which is huge.....well at least during my training stint with Trio-Kenwood Japan more than a decade ago. I reckon probability of an exact copy of the orginal cd is higher than one which sounds truly better. If otherwise, it could be the improved reading/tracking of cdp laser pickup on CDR media rather than the copying process. Just my opinion and I must admit my knowledge in PC audio is rather limited. R your CD-Rs scratched ? What is the data in it ? Music or Video ?? What drives have U tried to read them on n what's the result/message given ?

    Burned Audio CD-Rs

    R U refering to me ??? If yes, can enlighten me why do U say so ??? Not promoting piracy but rather pursuing Audio Fidelity. U have to buy an Original CD in order to do a good copy. Some people who want to preserve the Original CDs by not using them for playback will make a CD-R copy for playback instead. And they certainly want the CD-Rs to sound as good if not better than what the Original sounds. As for myself, the reason I went into this was bcos it was a hassle to always remember to bring CDs to n fro from home n my car. The head-units/changers in cars r using slot-in n not tray transport. So the tendency that discs may be scratched is high. Furthermore the heat built up in car under hot afternoon sun may damage the discs. So the most viable solution is to copy CD-Rs for playback in the car instead of using the Originals.

    Your analogy is interesting but not appropriate in this context. The theories n reasons, I believed evil-zen has already more or less answered U. CD-ROM is not = CD-R. CD-ROMs and DVD-ROMs are similar in that they are replicated discs—that is, the data are physically pressed into the disc when it is manufactured. ROMs are generally mass-produced and contain music, video, computer applications, or interactive games. CD-R, DVD-R, DVD+R discs are usually categorized by the metal and dye types used in the disc. These discs use gold, silver, or a silver alloy for the reflective layer instead of aluminum as in ROM discs. Gold will not corrode but is expensive. Silver is more reflective and cheaper than gold but is susceptible to corrosion if exposed to sulfur dioxide, an air pollutant that can penetrate the disc in the same way oxygen can—with moisture. Manufacturers use various silver alloys to help inhibit silver corrosion, and most R discs available today use a silver alloy reflective layer. The chance of silver corrosion from exposure to sulfur dioxide is less than the chance of aluminum oxidation caused by high humidity. Nonetheless, keeping the disc in a filtered “clean air†environment can minimize or eliminate its exposure to sulfur dioxide. With proper storage, these discs will outlast the technology. Manufacturers claim that CD-R and DVD-R discs have a shelf life of 5 to 10 years before recording, and under recommended storage conditions, CD-R, DVD-R, and DVD+R discs should have a life expectancy of 100 to 200 years or more. Sorry to hear about your wedding CDR. Most probably it's either due to lousy media or storage conditions.

    Yes U r absolutely right ! What this whole thread is about is to be able to recreate exactly or near to exactly how the recording was supposed to sound when it was recorded. It's not about adding "colour" or artificially alter the recordings to make them sound better. But the point here is the Original CD might not be able to do it's job as well as a burnt CDR. As to why, it's also already mentioned in the article. Unless the Original CD was perfectly pressed, if not chances r a burnt CDR might sound better.

    I wouldn't say the burnt CDRs has better resolution than the originals but somehow the clarity n details were 2 of the main improvements. In one of the blind tests, my friend just couldn't decide which one was the better sounding one even after repeatedly changing of the discs. Finally he chose the burnt CDR as he felt that it has a lower noise floor than the original.

    I have tried only 3 types of "black" CDRs. Melody, Sigma & Platinium. So far I find the Platinium one sounded best to my ears but unfortunately, I can't seem to find them in SLS anymore. If U need pics, I'll try to take some. These r the few albums that I can still remember which were used in the blind shoot-out. 1. Eagles - Hell freezes Over (XRCD) 2. 25th Anniversary - Teresa Teng (XRCD) 3. Close to You - Susan Wong (Normal CD but 96 khz/24 bit mastering) 4. Jazz at Pawn Shop - Proprius Records (Normal CD) Don't know if these r your "genre" of music.

    Whether it works for DVD (audio n video), I don't know but don't think so. And as of now, there isn't any blank "black" DVD medias. So far all the available DVD-/+ R/RW r all having blue dyes n there is no reason why they want to use black substrate instead of clear ones. The reason why black CDRs emerged was bcos of PS1 games.
  14. Don't know if this is the appropriate channel to post this thread but since U have to use a PC to do the copying, I guessed it should be here in PC Audio. I have personally tried it n even did blind shootout with a few friends who eventually admit defeat with my burnt CD-Rs vs their originals. All the albums used r my friends' favourite CDs which they r very familiar with. N the shoot-outs r done on their own set-ups where all settings remain the same while changing the discs. So far all 3 of them chose my burnt CD-Rs as the "better" sounding ones. Believe it or not, this is the article written by a net friend of mine Gary. In Quest of Absolute Fidelity Enjoy !
  15. Will try to find time to do it but I fully understand what U meant by GIGO Of course with a "lousy" source, no matter how good your interconnect, amp n headphones r, the SQ will not be improved. In fact my experience is if the source is "lousy", using high-end stuffs will reveal even more of the "flaws" as all the "details" r greatly emphasized. By the way, what interconnects r U using now ? Any cable which is significantly better than the Belden 1696A ? So is your PA2V2 with the "upgraded" caps ? Thanks.
