Sutteetat TW seem to have gone the root of VPI with a constant upgrade path, bearings, platters, feet, motors, ect however nothing wrong with that business plan.
After I purchased my two motor TW AC a motor controller and feet upgrade were offered which I got a great discount on from Cantolano, then a third motor option was offered shortly after which was praised highly in online reviews and TAS I believe including audio blog owner testimonials like here on Audiogon.
Now I'm not sure what MK version that I owed however reading the testomonials above including elsewhere owners seem to agree with everything said ,for the going price is the TW now a mature product or is it something else?, just asking.
I noticed you use Lamm amplifiers, I was an early adopter of Lamm ,with these few watts of power it's fantastic at driving certain speakers with a sensitivity approaching a 100 or more, just saying.
