Maybe he didn't word the statement as well as he could have, but (many/most/all?) unipivot arms certainly do have the limitation of azimuth and VTA affecting each other. Is SME V unipivot? Either way, nothing in audio was ever more frustrating for me than using a unipivot arm which simply was never "set and forget". On the fly VTA was pointless as I'd need to get out the Fozgometer to bring azimuth back in line each time.

Bazelio, I agree with you about unipivot arms in general. I find them very finicky. Some do, however, have magnetic stabilizers which are supposed to stabilize the arm and lessen changing azimuth as the record plays. I never really thought about it, but it does seem as though azimuth does change along with changing arm heights if the headshell is offset.

The SME V is a gimbal arm, not a unipivot. Fremer's comment was overly general, IMO.

Why does perfect azimuth (as opposed to 'close enough') matter?

Good question. My arm has a fixed headshell, so no azimuth adjustment. I have never experimented with this. With many arms, changing VTA will slightly effect azimuth. Changing VTF will alter SRA which may also effect azimuth. If people adjust these during set up, I wonder if they always compensate by listening and rotating the headshell. I kind of doubt it. My guess is that it matters "up to a point", with some changes being more audible than others. People may have different sensitivities to these adjustments.

I'm glad that that cartridges are so rigid and precise, and that their manufacture is so uniform, that such things can be set with perfection and override the groove force on the needle, which is a massive variable.

Really, OC disorder squared? Gotta perfectly discipline those grooves.

Do you guys think David writes on a blog as Fremer? Just read this.

"Audiophiles who tweak VTA to compensate for record thickness are wankers! Sonic differences, real or imagined, are usually because changing VTA, particularl on unipivot arms, will change azimuth and that is easily heard."

While not opposed to wanking not sure if holding it at 92 degrees is the best way, but each to his own :)!

I normally stand on one leg to achieve that angle.

Wondering how much magnification is needed to see that tip at 92 degrees?

Depends, is it Micro Ridge or Recplica 100 ?

I think it's spherical!

As long as it’s a tight fit in the groove, the fat lady will sing ! Opera of course !

I don't think that's fair to Ron.

Guys, this is all fun, but this last page of posts is just filling up Ron's travel blog thread and is really a bit off topic.
