CD Tweeks...Improve Ripped SQ?

demagnetizing , aluminium impurities, labeling color and blabla is BS!

Did you forget to supply the scientific proof that it is all BS?

Question is, have you even tried the devices to see if they made any difference? I bet not.

How about aftermarket power cords and Ics? Snake oil BS? I mean if there was a difference in sound from the use of aftermarket PCs and ICs the equipment manufacturer would supply the magic PCs and ICs with their equipment right?

Do you believe PCs and ICs make a difference?
If yes, how do you really know sure? Don't say from listening. Provide scientific proof by an independent testing laboratory.

I'm disc manufacturer and I'm holding several patent in the disc industry
molding process today is very accurate we talk micron and nanometre,in replication line we have scanners checking every disc,eccentricity is checked on the stamper during the punching and after with very accurate tester.

Patents? What does that prove?

John Bedini has a patent on his Clarifier as well as Furutech/Acoustic Rivine.

So what's in a patent?
.

How about some actual test measurement?

Bits are never just bits alone. A bit is an abstract concept with a binary state. Bits do not really exist at all in the physical world (point one out to me somewhere). The binary state has to be physically represented somehow, electronically, optically, however to be used. COmputers (and CD storage media) are designed to transmit binary data accurately, else they would not work at all. To get audio/sound, the binary data stream gets converted to an analog signal. The D/A process (which requires very accurate and precise timing to be done properly) is where pretty much all of the variability comes into play regarding resulting sound quality.

Rodge,

Sound from ripped files can be top notch if done well.

If you want to contact me by agon email to discuss options, I'd be more than happy to try to help. I am not a vendor and have nothing to sell.

Mapman,

Thanks for the offer.
Have to run at the moment, and will contact you in the near future.

I second Mapman's comment.

Pretty much everything I have read on the subject that I consider to be credible suggests that a CD that is in good physical condition, when played back in real time by a CD player or transport, will have very few if any read errors that are not corrected bit perfectly by the player. My belief, although based on technical understanding rather than experimentation, is that the main reason some CD treatments will improve the sound quality of a CD that is in good physical condition is that the treatments can make it easier for the transport mechanism and its servos to track and read the disc, which in turn will reduce the amount of electrical noise generated by the transport mechanism that may ultimately couple into the D/A converter circuit, where it can affect jitter, and/or that may couple into analog circuitry.

That effect may occur even in the situation where the transport and DAC are in separate components, as many and perhaps nearly all DACs will be sensitive to some degree to jitter that is present in the S/PDIF or AES/EBU datastream they receive.

That specific effect is of course inapplicable to the situation where what is being played back is a computer file that has been created by ripping a CD. So provided that you rip with software that assures bit perfect accuracy, I can't envision any means by which treating the CD prior to ripping would make any difference.
