Table/Cart Set Up - By Ear or Test Record?


Been on Audiogon for years and love the interaction amongst members - its both entertaining and educational.

Several threads have discussed how to set up various aspects of a table - isolation, VTF, VTA/SRA, azimuth, anti-skate, etc.

I have all the bells ans whistles - two test records, Fozgometer, Mint protrator, Feickert protractor, etc.

Over the last week, I set up my table by both using standard measurements via Feickert (spindle to pivot distance) and Mint (overhang,arc). Then set up cart using test records and Fozgometer. I then waited a week and reset everything else up again after Feickert/Mint by ear alone. Here is what I found:

By test records / Fozgo: quicker, less hassle, good sound

By ear: slower, meticulous, learned more, great sound.

For learning analogholics, I would recommened, time permitting, that you try both set up strategies and learn from them. I'm glad I did, but after this exercice, I will definitely agree with Doug Deacon and others, setting up by ear is the most sastisfying, educational, and will give you the best sound.

Actusreus, Nice post. You make the point that I tried to make in my earlier thread on the VTA/HTA topic, only you articulate it much better than I did. I use a MINT protractor and now can adjust overhang in about 15 minutes when changing cartridges, but still, I do obsess over it and get it to match the arc exactly. I find the Zenith alignment at the null points most helpful on the Mint. It is obvious that VTA adjustments alter overhang. I suppose those who adjust VTA on a regular basis feel that the sonic benefits of proper SRA outweigh the penalty of a slightly off overhang.
Doug, When I did move my arm base up vertically 2 mm at the pivot, I checked my overhang alignment on the MINT. I have a 12" arm, but I'm surprised by how much my HTA moved - well beyond my margin of error in set-up. I'm sure you and Doug don't adjust VTA by that much with your 9" arm. It was especially off the arc at the outer (lead in groove) edge. I start by lining up the inner part of the arc near the spindle. Then I check the outer part near the edge of the platter. If it looks spot on at the inside, it can be off at the outside by as much as 2-3 mm. This, IMO, is what is frustrating and takes time with the MINT.

My point is that I wish a slight change in overhane were just a matter of the stylus being off the arc uniformly by a small amount, but in fact, it is off by a varying degree along the length of the arc, and much more at the outside edge. How this actually affects the null points, I'm not sure.

I do, however, know that in a highly resolving system, slight changes to any of these parameters are clearly audible. Some more so than others. I agree with you that proper SRA is critical and then I would list VTF, then Zenith, then anti-skate, and finally HTA. I can't really adjust for azimuth with my arm, but I find my cartridge to not be that sensitive to that, or the stylus/cantilever is pretty accurately mounted.

I use the manufacturer recommended settings as a good starting point, and then make all final adjustments by ear.
