Tim, GMA uses fewer parts in the crossover than Thiel does. Those extra parts could be whats causing the harshness on some recordings. Give the Callisto a listen. I think you'll be impressed.
Thiel VS Green Mt
After listening to lots of speakers I still have not heard anything I like better than my Thiel CS 2.3s although the Gallo Nuc. Ref. 3s were close. I am at the point where only time/phase accurate speakers will do for me. I am very interested in the Green Mt Callistos but there are no dealers less than an 8 hr drive away. Has anyone compared these two speakers? I have a REL sub so the limited low end of the Callisto is not a worry. About the only thing I would like to change with my Thiels is the slight brightness on many recordings.
