I concur with Narrod assessments of the speaker choices. if within you budget? take a long hard look at the Wilson's Watt/Puppies, they will mate up very well that the Defy. As a matter of fact "Brooks" of Brooks Berdan LTD. Took "The best of sound" at a early CES (1992 I think?) with that same set up! must be a reason... also just out of curiosity what Mark is your Defy, 2-3-4? I may have some suggestions on the tubes for you, or perhaps member Rcprince can weigh in on this one?
cheers,
Craig
