Dialing in my analog rig - Need help

I took a giant leap forward in sound quality this past weekend after deciding to check the setup that was provided by the dealer. Hell, I watched him and thought he covered everything. I was largely unhappy with the sound of my newly acquired rig. I am now only slightly unhappy as I discovered the following.

Being that it was a used Turntable/cartridge with no manual I downloaded the manual and performed the following. What I found was that my cartridge was way out of alignment according to the jig provided by VPI. That was a painless fix I than checked the levelness of the tonearm as it pertains to the platter. What I found was that the tonearm was set (or never set) all the way at the bottom of its adjustment. Doh! So I cranked that up to "level with platter". Was that how former owner had it set? Then there was the alignment of the head shell and of course that was off too. Now I was on to the tracking force which I defaulted to slightly more than 2 grams. The gauge I have is kind of crude compared to what the dealer was using but then the dealer seemed to miss a few items anyway...

As I mentioned earlier in this post, although being very unhappy it has gotten a LOT better. Many smiles have practiced over the last few days but one thing that still plagues my setup is the graininess or lack of smooth sounding highs. It's detailed as hell but vocals still have a "grain" to them. Nice staging and a goodly amount of air. I just seem to lack the smoothness I thought would be natural to vinyl.

Setup is;
VPI Scoutmaster, Dynavector XXV Mark II which feeds a PS Audio GCPH phono stage then direct to a Pass Labs amp. MBL 121 speakers. No preamp yet - still looking.

What's next?

I can't for the life of me honestly say I can decern the difference in sound with different loading. I'm pretending to say that 100 ohms sounds about right, except of course the bit of high frequency harshness and general over the top brightness for lack of better term. It's just not warm of cuddly and I'm a nut about detail so I error towards lean.

I've researched the arm and come up with - nothing. Maybe it's a VPI classic 1? Doesn't say classic on the headshell though. This is a model 2005 Scoutmaster so I must assume that this is the original tonearm.

The VTA as I mentioned earlier was set (or not at all) to the very bottom of the travel. The arm angled upward. Who'd do that? Maybe that's why the table was traded in for a 10X more expensive model.

I've gotten some good advice leading me to the possibility of a known setup guru. Still wish to learn this craft myself.

Have you called VPI ? Maybe they can help with model id (and manual) when you describe it to them over the phone...

You should have the arm higher than level at the back. In spite of all that has been said in this thread it DOES make a difference if you get the VTA close if not exact (for all the reasons mentioned). Read the post of 4/2/11 on "VTA and cartridge loading" I put up for my slant on this subject.

Stops - it sounded pretty good tonight, but I know there's more there. I crank it up a notch tomorrow. I plan on rolling cables as well. It's still interesting though as I had this turtable dialed in by dealer with the VTA bottomed out!

I wonder how it would have sounded with the arm upside down?

I spent my evening creating a cat tree subwoofer enclosure. Don't laugh, it looks cool. I think I'm on to something..

"VTA depends upon the angle of the cutter head, which varies from LP to LP, and is not dependent upon the thickness of the LP."

Point being that if the LP is thicker then the rear of the arm must be raised for the same playback VTA as a thinner LP.

Y'all don't forget that line contact styli are more sensitive to VTA. As that is what I have and my new rig is a bit tricky to set VTA, I may do normal LP's one day then reset VTA and do 180/200's on a different day. Because of the vacuum I cannot alter the mat thickness.

Have fun spinning,
Robert
