I guess you can expect a factory installed arm/cartridge to be set up properly. I'd still want to check though even if only for reassurance that things haven't gone "off" in transit.


This was something I considered. I will most likely double check things, because as you implied, you never know what kind of beating the box took in transit.

This whole conversation has me intrigued about the technical limitations of vinyl. For example, is there a minimum or maximum frequency that can be "encoded" in vinyl (akin to the ~20Hz and 44.1kHz cutoffs on digital CDs)? Does this differ for 33s, 45s, 78s? Is there a way (based on the needle tip and equipment setup) for a knowledgeable person to precalculate the bands that the most noise interference will likely be in, and thus minimize or remove it? Etc.

It's particularly pertinent as I'm planning to attempt a vinyl-to-FLAC encoding soon.

I suspect the CD's version is simply an audio recording of the LP's 15 kHz tone section, record noise and all, hence the reason they are comparable to your ear.

The Beatles insist the random chatter, in this instance, is neither reversed nor has any secret message. It doesn't sound like backward speech to me unless played backward. [My turntable at the time could play backwards and I examined all of their stuff that was reversed, BTW]

There are several overlapping voices and in addition to the main voice I hear a secondary voice saying "[unintelligible] five by five".
