Upgrading from Thiel CS3.6 to Avalon


I'm considering upgrading my 20yr-old Thiel CS3.6 to Avalon Opus or Eidolon. Do you guys think it worth the upgrade? My listening room is measuring 17(W)x13(L)x8(H) ft.(speakers along the long wall) Which one(Opus or Eidolon) makes a better choice?
BTW, my other components: Esoteric K-05, Gryphon Diablo, audience Au24e XLR and cables.
Thanks!!

17x13x8. I recommend
Opus ceramique and add subwoofer.
I have eidolons and diamonds in my small room
A headache to deal with room dampening.
I went from Thiel 3.6 to Avalon Radian HC about 15 years ago. Still have the Avalons if that answers your question.
Thiel and Avalon sound is 135' different so only you can decide if worth while change by comparing them.
I agree with the post above - 17x13x8 is a tad small for the Eidolons. Avalon Opus plus a well integrated sub would be great. I have previously owned Thiel 3.6's. Avalon's are world -class. Unfortunately Thiels are good, but not great. It will be a significant upgrade.
