Setting T65C VTA
I found a very easy way to adjust the HK T65C tonearm height/VTA using a deck of cards as shims. I could not believe the impact it had on the Grado Sonata1 cartridge. Night and Day.
I was able to find a spot just to the left of the tonearm to slip in some playing cards to support the tonearm assembly. After loosening the rear spindle height set screw, I could raise or lower the tonearm height by varying the number of cards (shims). In my case, 10 playing cards was ideal. Any more, the sound became sibilant, any less and the sound became muddy. By varying the number of cards, I was able to tune the VTA by ear.
My headshell was also slightly twisted counterclockwise upsetting the asimuth. As the T65C's tonearm lacks an easy way to adjust the azimuth, I used a thin paper shim between the right side of the cartridge body and headshell to align it properly.
I recently upgraded my phono stage and power amplifier and haven't been enjoying vinyl as much as I had hoped. I didn't realize how sensitive the Sonata was with regard to it's setup.
