The importance of azimuth


Not a particularly sexy topic, I know, but I recently had a rather ear-opening experience with my VPI Aries 2/JMW-10/Denon 103D. I been enjoying playing records for hours--sometimes days--on end during the few weeks I've had the new 'table and arm (the cart I've had for years). But after endless tinkering with the VTA (adjustable during play--perfect for neurotics like me), even at the "ideal" setting for any given record, there was an unpleasant edge to the sound. It was almost as if everything was digitally remastered!

Needless to add, this was not exactly what I'd hoped for in a record-playing system, though it *still* sounded leagues better than my digital rig (Sony SCD-1), even with the latter playing SACD (no, it does *not* sound as good as vinyl--not yet, anyway). I added some damping fluid. No audible change.

Then it occurred to me (duh!). I'd only made a token adjustment of azimuth when I'd set up the 'table. It looked straight, the channels were well-separated and balanced, and basically I didn't want to screw around with it.

Big mistake. (I'm sure you were all mouthing those words already.) A loosening of the set screw and a bit of twisting, and...everything looked the same. Stylus descended to record...drum roll...oh...my...God! Voices and instruments beefed up and acquired shape, tape hiss magically appeared (where appropriate), and hard left and right images seemed to float about a foot outside the speakers.

I'm sure there are more scientific ways of setting azimuth, but I'm now in one of those situations where everything sounds so fulfilling of my expecations that I don't want to lose it.

Folks, never forget that in set-up *everything* matters. These are tiny increments of adjustment we're talking about here. Take care with everything and your hardware will reward you with the gorgeous sound we know is inside those records.

Never been all that crazy about the Helikon, the Aries/JMW arm or the Quattro-fil myself and think you need to wake up your vinyl system a bit as that combination will put you to sleep and no amount of adjustment is going to help the PRAT, where that combination will fall flat on its face compared to any CD player..........Time to look into a more dynamic cartridge and/or lead-in wire and you can do a bunch better than the Valhalla with its hole in the middle of the venue information that you could drive a Hummer through.....Sorry to be blunt, but you asked....
Put me in for a hundred too. By the time it makes the rounds, we'll all be ready to use it again!
David, count me in. Time to party!! Or, whatever you do with a customized multimeter.

Jbatlanta, I'll try to temper Rcrump's response a little, but both my partner and I DO hear VTF changes as small as .03g, and very easily. And contary to finding this onerous to deal with, we enjoy it. It's a hobby!
Ooooochie mama. Jphii. Send to me an e-mail via the 'Gon so I have yours and set the wheels in motion.
