I owned Theil 2.2's back in the 90's.
I went through quite a few speakers, including Maggies, Alon's, and Dynaudio.
The Theil's were my favorite and after I got them I had no urge to upgrade. Owned them for 15 years.
At the time they were 2,800.00 and worth every penny.
The Theil sound fit my taste for outstanding detail and imaging.
I drove them with a Conrad Johnson Premier, 7a at 70 tube watts per side.
They are capable of prodigious bass. The Connie J wasn't able to bring that aspect out, but the mids were glorious!
That was 20 some odd years ago. These days solid state amps have improved, so I would recommend a high current solid state amp.
If clear mid range, crisp treble and outstanding imaging are what you value in a speaker you will nor be disappointed with the 2.2's
Oh, the build quality and finishing are first rate.
