They need much more juice than your 45WPC tube amp provides. Sorry to say. I heard the Totem Winds in a Boulder Preamp and Amp system. It was a match made in heaven. The trebble was extended but NOT bright. We played everything from jazz vocals to big symphonic works (Mahler). On one disc (Susan Graham's C'est Ca La Vie), it was as if Susan Graham was walking around within the center stage. I had goose bumps all over.
Good luck.
