I finally got around to hook up the trio's. A totally different sound compared to my 20T's. I can't really say better or worse. The trio's need more burning in and adjustments, before I'll pass judgements. Electronics in use, are not my best, due to restrictions in space and to small rack Thank you hifi enthusiasts.
Improving the room/speaker interface is essential but have you ever tried those Echobusters Cornerbusters ($190 for 4.) They really do smooth out shoutiness & harshness like you wouldn't believe...they can also fix a good deal of timing issues related to over-exaggerated midrange echoes. Nice gear...you're on the right track!
