You have almost the same turntable as I do. I have the SL-1700mk2 which is the same but only semi-automatic operation. I use an Audio-Technica VM540ML and love the clarity and depth of sound quality across the spectrum with great dynamic range.
The SL-1200G /GR are very nice turntables, but I feel they aren’t -that- much of a step up from the SL-1600mk2, which has basically the same tonearm and while it has plenty of mass, it could use more isolation, which has always been a weak spot with the old SL-1200mk2 / md3.
I have recently purchased a KAB Electro-Acoustics tonearm damper. While I’ve yet to install it, it is reputed to be one of the best enhancements to the SL-1200mk2 tonearm, which is fundamentally identical to your SL-1600mk2 tonearm.
My advice is to keep using your SL-1600mk2. It might just need a little TLC (clean/lube the spindle, rewire the tonearm with litz tonearm wire, treat it to a new mid/high compliance cartridge, new interconnects and maybe the KAB fluid damper).
