I am only able to say that I spoke with a person (employee) involved with NuForces's German marketing (as I too was on to NuForce) and based upon this exchange, I suggest you to avoid trials here. But hey, different strokes... As I am a Pass fan I suggest you look no farther than Pass but if you wish, well, how about Red Wines' 70.2 monos [if you prefer the ultra-slim Nuforce sound]? These RWAs with TVC and tube active Promitheus' should perform superb together on audition with your 1027BEs given a proper interconnect and speaker wires. Terrific speaker - I understand your 'amp' considerations. Again, can you get a Klinger Favre for trial? You may have your answer with this amazing Frenchman.
