Bought a used (50hrs according to the seller) Grado Reference Sonata on the gon for cheap. Had a hell of a time getting it aligned last night. A word of advice for anyone new to vinyl, or just to myself for posterity: don't try to setup a new cartridge at 9:45pm at night. Its really best to wait until you have the luxury of a free weekend afternoon. Listening to test signals on the HiFi News Test LP is not a good way to relax for bed. 
 
At first I got the azimuth down, but then I realized the cart was way to forward in its headshell, so I pulled it off and started from scratch with the overhang gauge. What a total pain in the ass.  
 
But anyway, I think I'm reasonable happy with it, though I did fall asleep last night with a british guys voice speaking in my head against the backdrop of a high pitched tone (20 hertz... 19 hertz... 16 hertz... 15 hertz... 9 hertz [omg cartridge wobble O M G]) . 
 
From my very brief listening session last night, I can tell the Sonata is obviously richer and fuller then the Platinum. Its difficult to do a direct comparison though since the Sonata is a Reference and the Platinum is a Statement. Maybe I should buy billy's statement sonata, get a new headshell, and do a shootout with the PH-1.
