I owned Thiel 3.5s for ( 8yrs ) Loved Them! Drove them with Forte' monos (Nelson Pass design) and Spectral electronics. Thiels; at least the Legacy models are as you know, as an owner, are what everyone claims. Very hard to find a speaker as good or better for the money. I tried Pro Ac, Wilson, Sonus Farber but finally settled on Avalons. Opus w/ carbon woofers. The Eidolon come up for sale fairly often, I have never seen a pair of Opus for Sale. The Opus will fit your room well ( my room is 13w X 23L X 9h ) My opinion- The Avalons are superior. Better imaging / soundstage. Smoother top to bottom, no need for a subwoofer. wigs comments also apply. The Eidolon; I heard both at the dealer many times and (6wks) in home demo. But I settled on the Opus. They will fit & fill many rooms. Your equipment should mate well. Now that Jim and Kathy are gone. ( even though Thiel seems to be supporting the Legacy models ) I think you will find the Thiels to be getting long in the tooth and service to become problematic in the future.
If you can find a pair of Opus w/carbon woofers ( ceramic lack in the bass) You will never look back.
Best Wishes on your Journey.
