I own the PrimaLuna P2 driving Wilson Benesch Arcs. My previous speakers were Dynaudio 1.3mk2s, and I've listened to the PrimaLuna with these and the Dynaudio C1s. I love the PrimaLuna tube amp--but not with the Dyns.
The sound through the Dynaudios was too warm and undynamic for my tastes. My former amp was a Plinius 8100 and I preferred it to the PrimaLuna when using my old 1.3s. The Wilson Benesch is more transparent and detailed, making them a better mate for a tube amp. The SS amp and tube preamp suggestions may also be a better choice than an all-tube setup.
