I have a fully balanced TRL Dude and am extremely happy with it. Paul Weitzel is a telephone call away (like last night, Sunday) if you have a problem/question. I have had some great preamps: ML 32, Atma-Sphere MP-1, Aesthetix Calypso, EAR 868, C-J 14, 16 LS and so far it is my favorite, just because it does everything so well. Havent heard the Audio Horizons, though.
