I vote for the Modwright SWL 9.0SE pre...reasonably priced and the cost of tubes (Sylvania GB 5687 my favorite) won't break the bank. I've run that with my Nuforce 9SEs...guessing the V2s would have the same synergy. Don't leave the ICs out of the mix either. My favorite pairing has been with the Acoustic Zen Ref Matrix IIs.
