Cryo-treating CDs?

A friend who's opinion I respect, has experimented with both Cryo and demag treatment of his CD's and reports great benefit sonically. He says it improves smoothness and textures while making everything more cohesive.

I have not tried this myself, so I cannot speak from personal experience. If you do this test, please share the results.

I've had all my CD's cryoed for about the past 2 years; I have a cryo vendor located about 15 minutes away so it's pretty convenient. Smoothness and transparency, easier to follow bass lines, etc, etc. are noticeably improved. The effects seem to be more noticeable on particularly aggressive CD's, but sound is improved even on well recorded discs.

Apparently there is a dealer in Toronto selling cryoed blanks for $5 each because well burned copies on the cryoed blanks sound better than the originals. I don't do any burning/copying so can't comment on that.

Due to the nature of the material that is used in construction of the cd, they benefit greatly from cryogenic treatment. For full benefit to be realized, they do require a different treatment cycle than AC parts or wire.

In the case of both pre-recorded and blank cd's, a treated one will sound much smoother with more apparent detail. Cryo also seems to help with sibilance and the "spittiness" that some cd's exhibit.

Cryo also makes quite a large difference on DVD's. The black levels seem better on treated DVD's, in addition to the sound level benefits.

*In the interest of full disclosure--My business is cryo treatment.*

I have been using a Radio Shwag bulk tape eraser on my CDs for many years. It's cheap and it's like a Bedini on steroids.

Elgordo-please elaborate on the bulk tape eraser.
I've never heard of it but would like to know more.
thanks!
