To: a fool in paradise

Funny, my LPs are fine.

And - they sound much much better than CDs.

For years in my EE classes, I demonstrated CD vs LP on a very high end system, with audio levels precisely matched using sources that had LP and CD matches. The students were not told which was which - only that they were listening to either source A or source B.

When asked to vote, the LP never ever lost.

And - of course - some students felt that I was trying to fool them.

Oh, the EE class was in digital signal processing....so yes, I know the subject.

Digital guys depend on the Nyquist theorem for reproduction fidelity, but they ignore the quantization errors. I think that that is where the media comes up short.

I took DSP at the USCG from an amazing teacher by the name of Hartnett. He did the same thing to demonstrate that zero insertion and digital filtering wasn’t all it was cracked up to be.

He went out and bought up huge collections of albums predicting:

1. Morons would throw treasure out the window to make way for the CD.

2. CDs would eventually be exposed for what they were, and that not everything that should be preserved on CDs, would be.

He also warned that changing media was a convenient way for a civilization to forget all kinds of important recorded history, and that governments would one day use it as a tool.

All true, but for the average consumer the CD is a more sensible buy, because he is not willing to take the special care needed to protect an LP from contact with the needle [cleaning the LP, proper balance, proper cartridge damping, and so on.] And most turntables that casual consumers of music are willing to pay for would not afford sufficient protection even if he took the time and care required.

That’s great, as long as the LP doesn’t have any scratches.

I can remember as a kid, going into my grandparents barn, and finding quarter inch thick Edison records of my great grandparents, and trying to play them on my record player. The suckers played, and didn't sound that much different than the LP's I had. Even after 50 summers and winters in a barn.

Vinyl is Final not only applies to home siding.
