“By reducing micro-vibration in the CD spin during playback, laser-reading error is potentially reduced.”
🙄
of course they have zero measurements to back this ridiculous claim up
If you want the utmost clarity from your CDs
This product has been around for a long time.
Someone mentioned it recently in passing in a post, so I thought I’d give it a try.
For $35, it’s made an amazing difference.
It’s Herbie’s Super Black Hole CD Mat.
Considering How much I’ve spent changing components in order to achieve better SQ, this cheap little device is ridiculous!
The difference in clarity is palpable.
If you haven’t tried it you owe it to yourself.

Re reading error, even crude 50c computer drives have read errors around only 1-2 bits per million. You ain't going to hear them. Read errors are not the issue with digital SQ. Problems centre around jitter, clock errors, DAC clock integration with the disc player and the low bandwidth and sampling rate of the CD standard made unavoidable by the storage capacity of a 5 inch disc in 1984.
Even though the mat will not improve SQ, within 1mm or most probably more you don't need to worry about its thickness. From the get go the laser readers in CD transports are self-adjusting to locate not only laterally on the line of pits but also vertically to obtain the correct height above the disc to maintain focus.
So this is $34.99 snake oil. As snake oil goes, cheap at the price. |
And for an experience so intense as to seem almost tangible, who wouldn't want to just have to try it? |
Here we have the classic face-off between the view point of a pure subjectivist versus an objectivist with the knowledge of how the technology works saying based on the science, that the sound cannot be improved by this tweak. Unless the listener can prove his ability to identify the tweaked disc through rigorously conducted double blind tests…the effect has to be psychological. |
