Brownsfan,
Jusr wanted to share with you and the others on this thread:
1) Just took the 7T's out of my system, my auditioning process was complete for my formal review, and put the MG-20's back in place. Both of these are great speakers that offer similiar sonic virtues which is amazing to me because of the different approachs, planar vs box enclosure design, yet they both sing with a musical voice which is outstanding. The biggest diference between them is in the illusion of were you are setting in a concert hall or jazz club. For example, if you like about 10th row in a symphonic hall you would like the 7t's, if you rather be mid hall, about 20th row you would prefer the 20's. It's personal taste not what's right or wrong.
2) Went over to hear my friend's system, who after he heard the 7T's in my system sold his Magico Q-3s and replaced them with 7T's, who has much smaller room then mine. Yet, the 7T's were superlative in this acoustic space and still performed like they did in my rig.
Just food for thought. My hunch is something was going on, not with the 7t's unless they were malfunctioning, but with the setup or rooms. I struggled in my full length review on the 7T's to come up with flaws regarding their performance, so something was radical wrong I believe the day you heard them.
