TAS Recommended CD Tweak….


In The August issue of The Absolute Sound, RH gives a glowing review of a product from Digital Systems & Solutions – “UltraBit Platinum Optical Impedance Matching Disc Treatment System.” According to RH, he was floored and, “….This wasn’t a subtle difference; there was a wholesale increase in apparent resolution, space, clarity, soundstage dimensions, and vividness.”
Apparently, this is a liquid solution that is applied to CDs and DVDs ($65/bottle).

Regardless of the whole “advertising thing,” I don’t believe someone like RH would put his reputation on the line by giving a bogus review. I wonder what, “This wasn’t a subtle difference…” means to the average person’s ears?

Also, in the same article, RH makes the statement, “…Similarly, it’s incontrovertible that a CD-R burned from a CD sounds better than the original CD.” I did not know this. Have any of you come to the same conclusion?

There is a short discussion of optical impedance matching here in section 7.2.

A Google search for "optical impedance matching" will produce links to several studies.

Does George offer a trial sample?

It seems that if one were to send him identical burned CDs of the same recording, one labeled "A" and one labeled "B", and asked him to treat one but not the other without saying which was treated, then the effectiveness could be tested. Even better would be to do this to two or three recordings.

Then, after listening, if one believes they heard a difference between the discs, a call to George to learn which disc, "A" or "B" was treated, would confirm the listening test (or not).
