The OMA is fine as long as you place it on a MinusK Isolation platform. I am a big fan of Schroder tonearms, but I prefer the LT. I personally use a CB.
All of these turntables are luxury items and are in no way necessary for the best sound. Ownership is egocentric. I think it is important to note that the best performance is available at seriously lower prices. Blinded, nobody could reliable identify any of these turntables in a line up of great tables between 10 and 60 thousand dollars.
IMHO you might as well go for the one you think is the coolest, the one you can brag about the most. That would be the Work of Art for me. I think the OMA is butte ugly and the Esoteric is not far behind. All are trying too desperately to justify their existence by coming up with silly ways of doing simple things. To limit yourself to direct drive is self defeating. Suspensions and record clamping are far more significant.
