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?

Stilljd...Your understanding is flawed. Error correction is 100 percent up to the point where there are more errors than the code is set up for. The link that Shadorne provided is pretty good.

Another point...If an error occurs there is no extra time required to correct it. (Some have suggested that error correction causes the dreaded jitter). All the data with or without errors runs through the algorithm all the time.

ozzy & authursmuck, have ordered at your posted results to try (see my other post) I'm confident that it's going to make a nice difference and be cost effective in doing so.

El,

Yep, re-read the link with a different perspective and I understand the point.

Error correction codes do not prevent errors caused by stray scattered laser light getting into the photodetector. That much is clear.

Geoffkait...That isn't clear at all. A read error is a read error whether it is due to scattered light or a scratch on the disk. The error correction algorithm doesn't care.
