Heard them recently at Alterman Audio in New Orleans with a Quad pre/amp separates 4k combo. No fancy room, no treatment, no pinpoint setup, no magic wire or interconnects. No crazy racks and a olive digital sources.
My audiophile friend and I were very impressed. Loved them. Totally live up to the reviews. I have heard the Maggies with more expensive Audio research gear. The are both awesome but total different just as people have said.
All around I would pick the TI because I have a wide array of taste in music. They are incredible at everything. Love that you can run them with SS and Tubes. Love that you get killer bass but don't need an your amp to do the heavy lifting. Really cuts down on amplification cost. Also lets us use reasonable prices tubes with out sacrificing the bass. pretty compelling. I am really giving these serious thought.
Listen if you have a chance. Worth the audition.
