Is analog & vinyl anoying? Is it worht it.

I think that the carrier signal was at 44K Hz, but certainly above 40K. That of course forced cartridges to track at much higher than previously.
The response, however, wasn't necessarily flat to 44K and many carttridges achieved the higher frquency response by designing them to 'ring' at the carrier signal frequency.

I recently heard an A/B demonstration of Shine-Ola, and I was very impressed. ~$30/bottle.

I decided to try some eyeglass cleaner from our optometrist that we had in the house, and I was satisfied that it was effective as well.

One thing to keep in mind when cleaning CDs is to wipe linearly from the center hole to the outside edge; if you wipe in a circular motion, scratches can be put into the data stream and will cause long dropouts.

I really question the need to clean CDs. Except for a few with obvious major defects I have never had one skip. People who clean their CDs as if they were LPs seem to have a lot of problems. Draw your own conclusion. The error correcting encoding of CD data "cleans" the data stream.
