So I researched the inexpensive digital microscopes and they won't really do; one really needs to get the higher end ones like MF's, which enable you to take measurements - w/o measurements, it's still a crap shoot. I don't feel like spending $250 right now for this, would be nice if I can borrow one from someone local...

On the compliance, VPI said9.38 is nearly perfect, don't change anything

Shhhhh....that's OK, I bought three of them, one for each wandOriginally Posted by ack
You won't be sorry. I have always hated designs beginning with the Wilson Benesch arm where both azimuth and VTF were coupled
I'll defer to your research. Just know some people who swear by the $60 but I tend to agree with you. The more expensive scope seems a lot more user friendly. I also think that if you go back to the thread where we talked about setting SRA, someone actually used a telephoto lens and then made a grid on the computer? Maybe it was George who we rarely see here anymore?
I, at least, had done that - I had posted pictures of my arm with the XX-2, with a superimposed grid using a computer to show the slightly raised back and downward incline - if that's what you are referring to. This was my attempt at easily showing a 2 degree difference, but that's because I couldn't take a close-up picture of the stylus itself, although I did verify back then the 2 degree SRA with the same 10X loupe I will use now.
Basically, neither the picture/grid nor the loupe approach will be as good as a microscope with measurements, and to me, no measurements simply means more pretty pictures.

OK thanks!
Maybe it's just my age but those loupes drive me loopy nowadaysOne of these days, sooner than later hopefully, going to get me one of those better digital scopes!
It's probably worth it buying one... But the good thing about the human eye in this case is that it's fairly easy to tell a dead vertical stylus through a loupe, as opposed to trying to figure out if the angle you are looking at is 2 degrees or not - that's where the math comes in to set the expected SRA afterward, w/o straining your eyes. I think it's going to work well. What's unfortunate is that I will probably have to do it all over again after about 100 hours or so of use, as the cartridge sets in.

The A90 is mounted, aligned, and with the proper SRA as best as I can tell (yes, the rear of the arm is raised significantly). With one hour on it... the results are utterly impressive and realistic. Herb Albert's trumpets are right here on Casino Royal, as is Diana Krall on Live in Paris (which blows the CD away, BTW), and finally Heifetz's violin. Bass is extremely tight - the Telarc bass drum is very impressive and realistic. Impressive dynamics, 3D layering. I am equally amazed at the Ayre P-5xe... VTF is at 1.968g and unfortunately it can't go any higher, therefore I need a lighter counterweight... Let's see how it plays out over the next 100 hours. This is the cartridge that HP didn't care for?

What do you think about this?

I can't tell the brand, so no idea. I would really seek a Dino-Lite, as they are the leaders; see the link I posted above for Fremer's (newer) version; costs $249. I might get one too eventually, just not now - the math is all I need at the moment.
