If you want the utmost clarity from your CDs

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.

Do you mean 'so intense that it's inaudible'?

Well, it's your $34.99 if you have money to burn.

I explained in my previous post that replacing 1-2 bits in a million will be inaudible.

Is PALPABLE the most misleading word in audio?  It's certainly the most over-used.

Of course the best double blind test is where the palpables are asked to choose between the same material and system played twice.

Those who can do it, prove that it's all a game and that the human brain and psychology can convince their owners there are differences when there is none.  This is caused by subjectivity and limited ability to concentrate and clear the head of all extraneous issues.  We all do it.  Even the 'goldenears' who of course actually have ears like mine and yours.
