Sorry you are right, we are not talking about CD-Rs

see this link about coloring CD's

Alfe, the Snopes article on greening or using purple on CDs is filled with errors. In fact it's one giant Strawman Argument. Perhaps it was written by a recording engineer or a pro audio dude. lol. Maybe try over at Hydrogen Audio or AudioKarma, see what they say. Lol

Sorry I didn't know that I was hurting your business!

All of my shinny polycarbonate and aluminum platters have had CD treatment done to them.

The process I use is:
1) Optrix Cleaner
2) Audio Desk CD Lathe with black edge marker
3) Nespa Pro 30sec treatment
4) Acoustic Revive RD-3 Demagnetize

So the big question is...

Does a treated ripped CD sound better than an untreated ripped CD?

Anyone A/B a standard CD to a treated CD after ripped to a hard drive?

Thanks,

Rodge827,

I reread this thread again and I noticed, including me, no one asked you if you ran the test and listened for any differences.

So I will ask now, did you?

I recently picked up the new CD of John Mayer, "Paradise Valley".

I noticed the label is dark blue with gold lettering.

After listening to the CD a few times I thought of this thread.

Several years ago I had experimented with making a copy of a CD untreated then treated but couldn't remember the results. So I thought why not try it again.

I first copied the CD onto a CD-R, real time, in a Sony W222ES CD-R recorder.

I then spun the CD in the Bedini Clarifier, both sides.
I did a quick listen to the treaded CD and found the CD sounded a little cleaner, a little more detail. Like I said a quick listen.
I then copied the treated CD on the Sony.

For the sake of this discussion I will not go into detail of the differences in sound of the two CDs other than the treaded CD copy sounded a little cleaner, more detailed, than the copy made of the CD before it was treated.

Yes the two copies sound different.

Sound different on my 2 channel audio system. Sound different on my H/T system. Hell I could hear the difference in the CDP in the car.

I took the two Cd copies to a B&M dealer in my area for others to listen.

I did not tell anyone what I had done, just wanted them to listen for any differences in sound between the two Cds.

I used one of the dealer's audition rooms for my test.
I was able to get three different guys to participate in the exercise. Only one person entered the room at a time to listen to the two CDs.

I did not influence them at all, even when they questioned what I did to the CDs. I gave no information.

One at a time each listener could hear the difference between the two Cds. No matter how I would mix up the playing of the CDs each listener was able to distinguish between the two.

So why the difference in sound of the copy of the untreated CD and copy of the treated CD?

I have a friend that works at one of the hospitals in my area.The hospital has a high strength MRI machine. If I get a chance this week I will take a dark color label CD to him and have him take it into the patient MRI room and have him hold up near the magnet for about a minute. That should magnetize the hell out of any ferrous material in the ink of the label side and any impurities in the aluminum disc.

Any takers that want to listen to the disc in their CDP?
