I've only ever bought Lite-On drives, and my drive can read discs that my friends' can't read. I have not measured the burn quality, but I believe it to be very good. They are cheap too!

but i believe only the most experienced audiophiles can hear they difference.
Extraction errors are very obvious, generally resulting in clicking of some sort.

Splitting hairs

I think that looking at the individual manufacturers drives is a little silly. DVD and CD-ROM drives must have a certain level of error correction/detection or they won't be usable in modern computer systems. for audiophile user it's not the CD drive itself, but the D/A converters in the system (and where in the system chain they reside). I think that putting your money into a good DAC outside you system and running a straight digital signal into it would be a much better improvement in sound quality than messing around with different VD/DVD readers. Another option would be to get an extermal firewire or USB audio capture unit from Tascam or M-Audio. Typically the amps and the DAC converters in these units are of very good quality and you get the ability to do music if you want!

After trying a bunch of them, I tried a Plextor PX740A, and honestly there will be better, but I will not go back nor take chances while a product that we know is good enough. And as someone stated the ost iportant thing while burning is to do it at low speeds (the one also recommend to burn) and to use good media, Verbatin or the like, usingthose simple tricks, any will do the trick for sure...at least I have a really good result with those, and my DVD player will not play everything, any defect or any non good media will result in failure, as you know with "high end" DVD players, the higher you go, the less they play...

Now who's going to be able to hear the difference between the original and bit-perfect copy ?
I'm waiting to someone saying about "Yes, there are bits, but musicality is what you can't rip and burn"

Demagnetizing is always important too, http://www.actm.jp/acousticrevive/e/rd3-e.html
That's why there is Acoustic Revive RD-3...

For ripping I'd recommend installing AccurateRip for EAC http://www.accuraterip.com/ and sure to rip with Test & Copy, it rips twice and compares the integrity of files.
...and please if you share your rips, don't delete EAC logs.

That demagnitizer looks like snake oil to me. Someone tell me it's actually reasonable...

And I think the general consensus I have gathered for digital audio extraction is that CD-ROMs are the best, CD burnerss next, and DVD burners the worst, in general. I still use my Lite-On DVD-RW though and I don't care.

So like you can make bitperfect copies from movies or programs but when we're dealing with music suddenly the drives are bad and result in unacceptable quality? Right...

Error correction is better for data CDs. The format is better. The right audio extraction software that can check for errors. But the possibility for correcting them is not as great as for data CDs.

Aslong as the drive can read the disc then you shouldn't have any problems with rip quality if you use software that checks what it's ripping is what is actualy on the disc such as EAC. So far I have had only one cd that hasn't ripped perfectly IE shown as not a 100% quality track in EAC and had the ripped file not match the audio tracks hash file. This was because the was a spot of dirt on the disc and so my dvd drive couldn't read where the spot of dirt was. The effect of this on ripped file was a very distinct clickley beepey noise in the middle of the track. Cleaning the dirt off resulted in a perfect rip. I see no point buying an expensive drive just for ripping unless damaged discs are a problem.

I agree, snake oil... reason to make money and to amuse themselves of people who actually fall in that crap.
Hmm, really don't know about that what is the best, but at least some cd-players are actually CD-ROM and DVD-ROM transports like some Meridian, Audio Analogue and Mark Levinson (must be that CD-ROM mechanism should be the cheapest).

But the difference, it's the error tolerance/correcting.
What I remember Glassman told me was that the newest DVD+-RW's seem to be better than older drives. Lite-Ons are good, especially the ones with Sony optics.

100% Trackquality have nothing to do being bitperfect, it only shows how well it was ripped. If trackquality is below 100% it means some sectors must have been read several times. But like you said it didn't match the hash (CRC check). Most important thing to be sure it's bitperfect is to use test & copy in secure mode, it's though useless if drive doesn't have accurate stream what means drive use different offsets every time, CRC differ every time too.

Anyway test & copy is useful even without offset correction, if CRC matches it should be quite perfect. Btw, I'd use that "No use of null samples in CRC calculation" at least if "Fill up missing samples with silence" would be checked, I use both and those should be checked by default (found from EAC option/F9).

I don't think the reading of the CD is the issue since we have EAC. The question I have always asked is the burning process. I have found that T-Y media gives fewer clips and clicks. I have often wondered about the burning process, I had the famous BenQ 1640 which finally died on me. Now I have the newer BenQ which actually has a better sucess rate on DL DVD's. My process is orginal RBCD>EAC>Flac>DVD+DL. I have often wondered about the last step, I know there is MD5 checksum but never quite understood it.

Also, some drives will get around copy protection, others won't.

when I burn my EAC ripped Mp3's back to CD using nero and my sony burner I get random skips in the music Has this happened to anyone else? I wonder if it's hardware or software, I just haven't had serious time to diagnose! The drive is a pretty new dvd/cdrw from newegg, cost me about $40

Where are the skips, everywhere or just at the ends of tracks?

Are you running any programs in the background?
