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.

The assembly of my Shelter is visibly off-perpendicular relative to the body. Like 4yanx, I've done the best I can getting it perpendicular by eye using a mirror, but I've never achieved silence on the crosstalk tracks either.

Wally's Analog Shop, as referenced by Albert Porter above, measures crosstalk at the speaker terminals. That should better what we can do by ear. $400 including a copy of the Cardas test record. Very tempting. Can anyone think of a reason NOT to buy it (other than the price of course)?
Anyone want to go in and share one? Or buy one and rent it to me for a short spell? :-)
Giddy-up. Mr. Crump is trustworthy beyond reproach and "in" if this moves forward. I'm willing to handle this business. Anyone else interested, e-mail me.
Sberger....I'm with you . These adjustments just don't make THAT big a difference. Hundredths of a gram? come on. I've got all the stuff, too...JMW 12.5/Extended Aries/Lyra Helikon, and have to crank away on the old VTA before any sonic differences appear.

Reading this thread would make anyone give up analogue and buy CD's.

BTW, My Linn Ikemi CD player will kick the turntable's ass now that I put a Valhalla cable on the CD player. (Quattro-fil tonearm cable)

So, OK analogue guys, whazzup wid dat?
