I agree with Dave43 that your receiver will not properly drive the 2.3 [I also have used a pair of 2 2 from Thiel ] . I have no experience with the 2 other models so my comments are limited to the larger Model .
I do want to point out that a well built [ can handle the lower Load ] Tube amp of 120 Watts or more , can sound very nice with these Speakers . Most VTL , Audio Reaserch , Conrad Johnson , etc. of 120 Watts+ will be fine .
