Interesting perspectives. I'm always thinking about what sounds like really cool technology for turntables and then also how long that part last or that sensor or re-calibrating. I think the SME Model 60 was just released and I don't think that table is doing live monitoring of the speed and making corrections....I think you calibrate it and leave it?
The Döhmann Helix One MK3 looks really cool! Might be out of my budget.
That Esoteric Grandioso T1 Magnetic drive systems looks really cool as well! But I think it's a step up from what I'm looking at.
