Technics SL-1200GR setup question


Hey A'goners,

I recently purchased a Technics SL-1200GR TT and am very pleased with it. I purchased used and it came with a Denon D-110 cart.

My understanding is that when the VTA is properly setup, the tonearm should be parallel with the surface of the record. In my case, the arm tilts down slightly. In other words, it's higher in the back and lower near the cart. The tonearm adjustment is as low as it goes. If I lift up the tonearm to make it level it is probably a good 1/4."

Does anyone have any suggestions here? Is this common or an acceptable degree of tilt? I don't think a shim is going to get 'er done here. 

I appreciate any and all suggestions. 

Thanks,
Joe

You could use thicker mat or a spacer between cartridge and headshell if you think it’s critical.  


From VdH interview:


“In play position, your tone arm should not be parallel to your record but at a small angle: around 3 - 5 degrees. This can be achieved by lifting the tone arm at the rear (i.e. the bearing part and not the cartridge mounting part) by 4 - 8 mm. The sonic result is a better spatial reproduction and cleaner high frequencies.” 


Chakster, Was vdH talking about a general rule for all cartridges or about Denon cartridges or about the Technics 1200GR or what? Because that single suggestion is unlikely to be optimal for all combinations of tonearm. cartridge, turntable.
To the OP, are you sure there is not some further adjustability that you are not accounting for? Because there is nothing particularly esoteric about Denon cartridges or about the 1200GR that would lead me to think the VTA adjustment would be so restricted.  Some folks even like the pivot to be lower than the headshell end.

More from this interview with VdH: 

“What I learned was that in the playing position the arm must always be somewhat higher at its rear end (the counterweight end). A 9 to 9.5 inch arm around 7 - 9 mm higher. This improves the resolution a lot. Works with any arm and any cartridge. What you have to keep in mind is that each record is different. So fine- tuning the spatial resolution is slightly different per record. This can be fine-tuned by changing the distance between the arm bearing and the mounting board.

One millimetre up or down can be enough. But the average of 7 - 9 mm up works always in your advantage.”

Ugh.
I’m sure the added distortion is likely to offer more of that warm, tubey-like analog sound. Some people like that.

I prefer neutrality, and have found a phono cartridge manufacturer’s VTA spec - typically around 22 degrees or so - yields the best result. In practice that means the pickup arm is level or very nearly so.
