Just got my Scoutmaster, need setup suggestions...


Hey guys,

Just got my Scoutmaster (actually got it 2 weeks ago but just got around to setting it up now). I set it up as best I could with the dealer's help over the phone (for 1.5 hours). This was my first TT that I ever owned, much less set up.

Now, I balanced the tonearm + Dyn20XH to 2.0g using a Shure gauge... it took some trial and error, but I got it pretty close.

Now, the sound is overall very good, much better than my digital front end by a very good stretch. The only gripe I have is that image is a bit to the right....

I switch back to my digital front end and the image is dead center.... so I know it's not speaker/seat positioning that's off.

The Scoutmaster uses the JMW9 tonearm... and there's a weight in the back of the arm that one uses to calibrate and balance the arm/cart on the gauge (sorry if I'm not using good vinyl lingo here). I noticed that the weight is a little off kilter though... making the tonearm skew a little bit towards one side moreso than the other (rolling more towards one angle).

Is this affecting the imaging?

Azimuth is the fancy term for how the arm sits on the record, looking at it from the very front - in the face of the cartridge. It should be absolutely horizontal to the record. Its exactly what I suggested to you above.

Read this and look at the illustration. It'll help you understand how to set it up.
Also, invest in a good protractor if you don't already own one. turntablebasics.com has a good one.
And I suggest a digital gauge.
Joey, Simple Layman's Terms of Azimuth.... That the Stylus-Needle is perfectly vertical to the record's surface, and grooves. Us nutty vinylphiles will use a host of goodies, and doo-dads, such as magnifiers, jeweler's loupes, thus inspecting that cartridge alignment is exact in all planes. Some Tonearms, suchas my Audioquest Arm have no provision for Azimuth, but aparently yours does. If there's any sort of adjustments on your Arm-Table, count on them being out of whack, and you cannot take anything for granted.

Another aspect of the JMW Arms, or any Arm for that matter, is Anti-Skate. If an anti-skate is so badly off, this could possibly cause an imbalance, but some gurus say anti skate is a non issue. I wonder why though, if the stylus is pressing so had to one side of the groove, and neglecting the other, how they say this is a non-issue? Time will have an impact I believe on the record, and also on the stylus itself I believe if antiskate is so far scewed.

If your problems aren't solved by any checks of the Tunrtable, and Arm, then I would go on to suspect a bad phono stage. If it was a Tube Stage, I might suspect a bad Tube. Otherwise, there's also the possibility of a bad cartridge. Of this is all bought new gear, I would try to resolve this issue, as the dealer should then make eveything right if there's a problem.

Just back from RMAF and the Roy Gregory analog demonstration was nothing short of revelatory as far as the differences minute adjustments make esp. to VTA and alignment but also the postion of the cartridge in the headshell. I know very little myself but I know what I heard. Both he and Richard Foster demoed the averaged "prescribed" VPI set-up vs one with more care and the use of a better than supplied protractor using same arm and cartridge on a VPI TNT HRX with Lyra Titan. Man it was the difference between hearing ordinary subdued sound without any real objections and having the singer sing directly for you, fully present- all the difference in the world. At all times it was played on a first rate system with 20K Zanden phono pre and at least 25K worth of CJ and Nordost. It totally threw my usual beliefs about better components and better synergy always equalling better sound out the window. Set-up is absolutely vital and probably their prescription on set-up rather than anyone else's. Let me say: Beg, borrow or steal to get that knowledge and get it right if you paid a dime for your VPI.
I was able to "fix" the counterweight on the back of the JMW9 tonearm and get it to be a bit more balanced. However, I am now away from my TT and I just read the prior posts talking about the Azimuth. I get what the Azimuth is now, but I was not able to tweak/work on this aspect as of yet.

The image has definitely improved and has gone from the right and it is now pretty centered. The only problem I have is I feel it should have more weight to the central vocal image.

What else can I do to improve vocal weight?
