I have the 1200 G, and I believe arm adjustments to be the same as on the GR.
The issue audionoobie raises is one I have myself sent requests to Technics' support about, but never received any answer. The fact that, although there is on-the-fly VTA adjustment on the table – it does not let one lower the arm down to the parallel level or below. I do not understand that anyone can insist that parallel is always right (or even the 7-9 mm raised back end). Correct level/angle varies from cartridge to cartridge; dependent on stylus rake angle, cantilever angle and compliance, cartridge height. I switch between 2 cartridges (Soundsmith Zephyr MIMC * and Benz Micro LP) and both offer better bass (not just more, but clearer and better defined) when I have set the back-end of the arm lower (i.e. below parallel). My prior deck (VPI Super Scout) had a much larger adjustment range than the Technics arm. Raising the back does not only cause the bass and lower mid-tone to become less distinct, but also carries a high-end distortion penalty – like sibilance. I have seen others complaining about this on the Technics, so it's obviously a design error. I have tried to work around the problem by using two mats at a time (cork/rubber and/or cork/leather) but it does not give me enough as the spindle is very short, so this leaves no room for a clamp or a record weight. I wish Technics would own up to this problem and come up with a solution.
