Is analog & vinyl anoying? Is it worht it.

Viridian...I agree that it is astonishing that a mechanical media like a vinyl LP can sound so good. With some dynamic equalization (instead of the fixed RIAA curve) it can be as quiet as a CD, and with reduced distortion. (This was the DBX LP system, which I once had).

I believe that the CD4 system used a carrier with frequency modulation above 20 KHz. Because it was FM an undistorted waveform was not necessary. It was intended that the rear channels have full bandwidth capability (20 to 20K) so the cartridge had to work up to 40 KHz. In fact, although CD4 was a flop, phono cartridge design was greatly improved as a result of CD4.

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.

Gonna take delivery on new cd player. Don't need preamp. What's a good cleaning method for cd's?

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.
