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.

You might want to review the vinyl myths page in the wiki, especially where it talks about frequency limits.

You will find that different records have a different-sounding "whoosh" of noise imparted by the rush of the groove vinyl along the stylus, so I can't imagine any way to predict that noise exactly. Speed is one of many factors in that.

Ah! That makes for an interesting read, and does indeed answer many of my questions. Thanks for pointing it out.
