In Reply to: RE: Do You Have a Favorite Disk for Setting VTA/SRA? posted by Mel on October 14, 2014 at 08:30:24
Yes, I do. I have two in particular that I use- the 200 gram Mo-FI Anadise of Bob Marley's Exodus, and the plain A&M (130-150 gram?) version of The Police's Ghost in the Machine. I generally set VTA somewhere between too low for the Mo-Fi and just too high for Ghost. Although, I have heard both with optimum VTA, and that is the sad thing for me-
The problem I have (and believe me, it is a LOVE/HATE relationship), is that Linn arms do have an adjustment for VTA (a single Allen head screw at the side of the arm collar), but you can't do it while the record is playing, AND the settings aren't anywhere near repeatable/accurate.
However, when VTA is set for the Marley Mo-Fi, the instruments snap into focus- in particular, the tambourine that enters on the song "Waiting in Vain" can scare the crap out of you, sounding like someone has walked into the room and started playing the darn thing!
With VTA adjusted for Ghost in the Machine, the mix sounds exactly like that- a MIX of different room acoustics and processing. Stewart Copeland's drums (specifically, the last song on side 1- Demolition Man) are completely thunderous and have a presence that is almost "in the room" with you (or are you in the room with the drums?).
I'm sure that if I ever have the ability to adjust VTA during play back, I'll be right back into Audio Nervosa again. For now, a good compromise is in order, at least on my table...
Cheers, and hope this helps!

On all of my 'tables with adjustable VTA, I find the sweet spot and then fit a stack of playing cards between the plinth and the bottom of the arm lift (on all three of mine, the arm lift assemblies have flat bottoms; not sure if that's common).
I discard until I have a tight fit, then wrap the cards with a rubber band and a include a note to remind me of which turntable belongs to that stack of cards.
A valve gap gauge for automotive use does an excellent job of measuring the height between the arm and the collar, making it easy to repeat/reproduce the VTA setting on a Linn arm.
Here is what it looks like:

Nothing useful to add, really...
' Agree with the use of feeler gauges but mostly posted 'cause I saw your name and wanted to say hi.

It isn't attached to the arm, nor can one adjust it during play ($1 million Obama-dollars to anyone who can prove it to me otherwise! LOL).
This below is one of my "soon, but not quite yet" items on my audio wish list-

A solid connection at the arm collar is critical to the sound quality of an LP12, so on-the-fly VTA isn't an option. I guess I don't see how using a tool is "cheating." You need an Allen wrench to adjust the VTA and I don't see how that is "cheating."
Enjoy!

Actually, what you propose is a neat idea.
The MG-1 is pretty sturdy though! I've heard it (on one of the better Micro-Seiki tables) and was blown away! It's on my short list of 'table upgrades. But first I have a Herbie's Mat, and a PSU from Phoenix Engineering to purchase- probably in that order!
