oblgny.....I totally agree with you about being nervous about any changes, because I have become very protective in preserving what I have and uneasy about potentially loosing it....like with normal wear from aging. As I test more speakers, I have become increasingly aware of just how musically engaging my Thiels are. I recently bought and sold some much more expensive Revel Ultima2 speakers after only having them for about 2 months. They were touted as having all the attributes that I like about the Thiels, but it was obvious from my first listening session that my Thiels would be back.The Thiels just seem to make the whole listening room come alive, while all the other speakers I've tried just seems to project sound from between the speakers.
I'm currently using them with the Audio Research Ref 150 and Ref5 with a tube modified Modwright Oppo 105. I have been told numerous times that 150 watts of tube amplification is not enough juice for the Thiels, but for my listening volumes, it seems like plenty.
jafant.....I'm glad that I found this thread and will "follow this discussion" with email notifications.
