Do you demag or destat your CDs/DVDS?

I spoke at length with my high-end retailer, here in MN, who swears by the Bedini Quad Clarifier. He states he never uploads a disc to his solid state drive or plays a CD that is not first placed in his Bedini. I trust this guy....

A point to consider, regarding the mention of ripping to an SSD (or other hard drive): If in fact demagnetizing a CD accomplishes anything, and if the explanation of how that might occur is as described in the long quote from IAR which Jim (Jea48) provided on 7-9-11, the resulting benefit would only occur during real-time playback in a CD player or transport. The effect described in that explanation has no applicability to playback of a computer file that has been ripped from a CD. And that is especially true if the rip is performed using software that assures bit perfect accuracy, as it should be.

The IAR explanation, btw, involving introduction of electrical noise into circuitry in the CD player or transport, is the most plausible explanation I can think of for how these things MIGHT make a difference. And if that explanation is correct, whether or not a benefit will be realized, and its degree, figures to be highly dependent on the happenstance of the design of the particular player or transport.

Correction to my previous post: "7-9-11" should have been "7-9-14," of course.

Hi Jim,

Voila!

Brownsfan, thank you kindly. And I'll add for the benefit of others that if any differences were there to be perceived with the particular device you tried, in your particular high quality system, I have no doubt that you would have perceived them. IMHO your sonic perceptiveness is as good as it gets.

Jim, can't do, as I'm not equipped for computer-based playback to my main system, or to anything other than inexpensive computer speakers. Despite being among the more technically oriented audiophiles, somehow I always seem to be among the last to adopt new technologies :-) I didn't buy my first CD player, for example, until 8 years after the medium was introduced!

In any event, comparing CD playback to playback of a computer file introduces so many variables into the mix that I'm not sure the results of a comparison in a specific system would mean very much. That would likely apply even if the CD were being played back in a CD drive in the same computer that contains the hard drive, due to the differing signal paths within the computer resulting in differing amounts of noise and jitter on whatever output signal it is providing. To a greater or lesser degree, of course, depending on the type and quality of the interface being used between the computer and the component to which it is sending the signal.
