Sibilance -- that last little bit...

Dougdeacon:

I remember reading about the optimum method of settimg azimuth by measuring the voltage between channels as you describe.

I tried to measure the output voltage at the output of my table, as well as at the output of my monoblocks. With my voltmeter set @ 400Mv DC and I get nothing.

Anyone have any ideas as to what I am doing wrong ?

I took these same LP's to a friends with an HRX, JMW12.5 and Benz LP, Asthetix pre.....same noise. Yep the records sound great until INNER GROOVE DISTORTION hits!
Remedy....compact disc!

Begging to differ. The remedy is a better groove tracer than a Benz LP.

Focusedfx,
I'm unfamiliar with the 10x4 so can't say whether it can trace really tough inner grooves cleanly or not. I know a ZYX Airy 2 and above can, and that Benz's, Denons, Grados and Shelters cannot. They don't have the stylus profile for it.

I'm also unfamiliar with the WT protractor but I own the HFN record and its paper protractor. It's pretty poor stuff. If your arm is compatible with Baerwald alignment you should consider springing for a Wally Tractor or trying the poor man's version, the TurntableBasics. Either one should be superior to any paper protractor. The mirrored surface makes sighting and squaring the cantilever and squaring the azimuth of the stylus easier and more accurate.

An alternate consideration may be, that if the records evince this distortion on other rigs, perhaps the inner grooves have been damaged by previous playings.

True enough, though IME inner groove mistracing and physical groove damage sound very different.

I see where you are coming from Doug, but he describes the problem as "sibilance". Do you think that would indicate mistracking or groove damage?
