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.
Outside of better speaker placement if possible. I would relax and buy some music before I get into changing such a nice system. Might consider good headphones should not always be able to play your music out loud. Upgrade or not, you have assembled a sweet system.
