What to expect from MONO


Hello:

I'm curious if when listening to a 'mono' LP, should I be hearing a completely symmetrical sound stage? I'm listening to Coltrane's Blue Train in mono and I have to say that it favors the left channel on some instruments like the cymbals. The horn is mostly centered. I'm using a VPI Scout with Dyna 10x5. It's new and set-up by the dealer. Could this indicate that something is not set correctly?

On a separate thought. Since everything else in a system needs to be broken in (cables, speakers, carrtridge, etc) does new vinyl need to played a few times before it sounds it's best?

I have a ZYX mono cartridge on my VPI 12.5 arm and about 500 mono LPs. I use two speakers, rather than just one. I have tried it both ways and prefer two speakers, though I can see why some people prefer a single speaker. On my system, with two speakers, I do get a horizontal sound stage with mono, not just a vertical line. The mono horizontal soundstage ranges from 1/4rd to 1/2 of the size of the horizontal soundstage of the stereo version of the same recording played on the same arm with a stereo cartridge, a ZYX UNIverse.
I use a Wallyskater to measure the anti-skate on my VPI 12.5. It is possible to get the anti-skate fairly close to optimum by just twisting the wires.

For a lengthy discussion of why test tones are not very useful for setting anti-skate please see the following thread.
