Disclosure: I retail Well Tempered turntables, Departure Audio.
I have never A/B'd them directly, but I owned a VPI Scout with JM memorial arm and now own a Well Tempered Amadeus. Both good tables, but sonically, no comparison. To my ears the Well Tempered performs at a much higher level. Quieter, deeper bass, bigger sound stage, more musical. Maybe the higher level VPI models even things out, don't know. I do feel the Well Tempered competes well with tables at many times its cost. I think you need to get to the mega buck tables to significantly better its performance. I have owned Linn's, Technics, VPI's and SOTA's, all good tables, but bettered significantly by the Well Tempered from a high value/high performance perspective.
