I am a huge Rock fan. The issues with the Rock 3 would concern me.
But damn, a Rock Reference. Wow. This is supposed to be a mighty fine table.
I have not heard SOTA. But I don't see the kind of raves for their tables that the Rock gets. I am not sure that the vacuum is necessarily going to deliver the types of benefits that the trough gives you on the Rock. The Townshend 7 clamp does a great job on my mildly warped records. But if warped records are an issue, I'd suggest just getting a Vinyl Flat to take care of that, and focus on other, more important aspects of turntable design than flattening LPs.
