The OP asks for a comparison among 3 choices of phono and got almost nothing but suggestions that he consider a 4th, and there’s virtually no consistency regarding a putative 4th alternative. I’ve owned the Rhea which I converted to Signature status. The Rhea Signature version was way better than the base version. Otherwise I advise the OP to choose on the basis of features, because all 3 on his list are very good, provided that you sub in the Sig version of the Rhea. I have a slight bias in favor of the VAC Ren, but it’s not well founded.
