Hrmmm, how to proceed, as there will always be someone always wanting to justify their procession.
The arm on the Technics are not crappy. The ADC tonearm is not crappy, just limited as the modern vinyl world has moved away from high compliance cartridges and low mass tonearms. This has been more apparent to me as I am even more limited having a SME arm.
Depending on which Technics arm that is being referred too, which alignment tool use and the condition of the tonearm itself, I can't say the ADC arm is a better tracker. Neither of them had any issues with tracking when I used a variety of mix compliance cartridges (Shure, Grado, Nagaoka, high output MC, Audio Technica, Stanton etc...).
The automation in the Q60 is probably like the Q50, it runs on polymer gears and rubber belts. So yes, eventually, it will have the same problem as the SL-1600mkii. These tables are getting old.
The extra added stylus hour counter and stylus gauge are niceties but, not necessary. You can get a digital scale and for many of use who buy second hand stylus, the counter is a bit moot. As a digital microscope would probably be more accurate than hours of use on the wear of the diamond. Both methods, however, cannot tell you when a suspension has gone bad.
The SL-1600mkii like the 1200mkii has a stylus light, which the Q60 doesn't have. But, I guess one could buy a lamp.
The SL-1600mkii is also suspended, unlike the Q60. Luckily, my rubber dampers are still in good shape. It provides added isolation. Though, I guess a platform of some sorts can also provide similar performance as I the Technics suspension isn't that great in comparison to 3-point suspension. And, I guess the Technics could also benefit from a platform too.
At least from the Q50, the platter on the SL-1600mkii is heavier (I believe) and had a rubberized undercoating, which the Q50 didn't have to help provide further damping.
The SL-1600mkii also has VTA which the Q50 didn't have and from what I can tell from pictures, the Q60 may not have. VTA is very nice to have as it now allows for greater flexibility in tuning the cartridge.
From the underneath pictures of the Q60 I've seen. I can probably say that the cue arm, drop like a rock and sky rocket upward when using without the automation, might be an issue in the future.
Once again, these tables are getting old.
