certainly is not! but i can assure you that stamping discs is way faster than burning them. Anyway, that's why i like .wav files and a big *** hard drive!

^^ absolutely correct. stamping is MUCH faster

Just another experience to share.

I have 2 cds, one is an orginal commercially stamped CD and one is a copy of the same cd, which I burned using a regular PC cd burner.

I played it in a really high end home stereo. The cd players were two Denon "turntable" cd units with a denon mixer, crown amp, and some crazy speakers I've never heard of before... but with the aforementioned lineup of equipment I'm sure they were high end.

At any rate I played both CD's and used the crossfader and played it for my girlfriend switching between original and burned. She couldn't tell the difference.

We then switched and she operated the crossfader, and I certainly couldn't tell the difference between the two...

^^ I agree, I can't hear the difference on my high end home system either. I don't doubt that others can, but so far no one I've met has been able to at my home. It's kind of a little experiment that's been going on for a while now. Even on a fast burn 24x on my computer I can't hear a difference. Anyway, to each his own, like I've always said," the only nut that needs pleasing, is in that shell attached to your neck."

Hey, my name is Brian Folk. Just off baseline so you have any idea.

Burnt cds have to be perfect. Think of computer programs that run off them!!! If a couple of bits are wrong then a program can crash. Thats why there is data correction and checking. Cd players dont care about that stuff and will keep on playing(in minor cases), but when on a computer it HAS to be perfect in order to run.

PS Im graduating this year in electrical engineering and we are learning this stuff.

IMO for just daily listening, good quality mp3s are fine. In fact I kinda have to because I hardly ever buy an original, just copies. If im doing work on my system then I would use an orig.

THat's what I was gonna say. If a few bits are wrong you aren't going to notice a lesser quality sound but you aren't going to have sound at all, if anything it will be a blip or quick squeal. It's digital remember, not like wearing down a cassette where you will hear the difference. As long as the file is not compressed to the point of you making it lose it's original content putting it onto a burnable CD will not make any difference. I am a computer technician/mobile electronics tech and in many ways they work together.

Also there is new formats of lossless audio out there, APE, FLAC just to name a few. If you rip it to FLAC or APE, send it to someone else (or download it yourself) and then put it on a CD it will be 100% EXACT as the original in every aspect, except the CD art of course.

Also, beyond 160kbps there is very little audible difference, not to say that it cannot be heard. Lossless is compressed but will retain every piece of data from the original recording, and still plays at an average of around 1000kbps.

That's my stance

For sure you can tell the diff between a crappy mp3 and a good mp3 song.
Sometimes its the luck of the draw when getting songs, sometimes good songs only come at 128kps lol.. but for the most part, their all pretty much 320kps or if ripped from a cd , higher..

I can't tell the diff between a ripped cd anf an original.. I use XBMC to rip all my cds at the 1:1 ratio, and the size is just crazy . that why you can burn .wma cds and play them on your hu, cuz the quality is just as good as cd quality off the press !

wma is not really a better compression method for quality over the mp3. WMA can be encoded at a higher quality rate, like 480 i believe, but wma cuts out alot of mid-bass and bass frequencies so that the sound is percieved as higher quality, because it focuses the quality on the mid-high to high tones. As I said before, that is why compressed lossless audio is in right now - you can't beat it. As good of quality as a .wav without the massive file size. Also it doesn't matter how you rip. 1:1, 10:1 isn't a measure of the quality, it's of the speed of the rip. As long as the cd doesn't have scratches you can rip very fast. If you rip a cd and your songs skip, then you need to slow down the rip speed to hopefully correct the errors.

true or false

burned cd s have a stronger bass than original.
rumour ?
at the concepts show they use a burned disc and was told my bass is too strong at iasca shows where an original disc is used my bass is too soft.

home stereo testers say no difference
