Like I said, my answer will be considered unconventional, but to clarify what I meant; I think its a matter of degrees (pun intended
). If your shelf is tilting to one side by 5-45 degrees
then I too would worry about uneven wear on the bearings and pivots etc, but if you can't even visually see
that it is tilting, you only know from a bubble level that it is (say, 5 degrees or less), then I think the pertinent factor is that the tonearm calibration (balancing, subsequent tracking force application, and anti-skating force) must be set while
in this slightly "tilted" position. And of course re-calibration is a must if later then moved to any other
To my mind, worrying about uneven bearing and pivot wear (due to a tilt of under 5 degrees) would be akin to worrying if placing the axis of your turntable's magnetic cartridge in alignment with the earth's north-south magnetic field, vs. perpendicularly to it (east-west), would have an adverse effect on its output. After all, the earth's magnetic field has the power to spin around the relatively big, heavy needle of a pocket compass, why wouldn't it have an effect on the weak magnetic field generated by the tiny, moving iron/magnet/coil inside your cartridge?
Of course ideally
, you should do your initial calibration on a level shelf, because that way as long as you only move the turntable to other
level shelves, the calibration is good to go! This is where the whole "leveling is critical" mythology comes from!
But when faced with a slightly unlevel shelf and no sturdy
way to level it......
For those of you who disagree with me, I have two questions for you:
A) Does failure to critically leveling the turntable merely compromise performance? or actually (over time) break the turntable?
B) If it is so critically important, why do many turntables not come with a bubble level? Would it really cost that much more, considering they buy them in bulk, to throw one in for free with the purchase, since it's "so important"?
Oh, just to confuse all of you even
more, I'm sure if I looked on the web I'd find thousands of sites that contradict my advice and none to support it.
I guess I'm a "don't-believe-everything-you-read" kinda guy.
