Why not buy a used Fidelio Encore instead of the Rienzi? I've been listening to Verity for years and find them to be one of the best speakers made. I owned the Tamino and found much joy in it, however I always took the pilgrimage to listen to the rest of the line at a local shop.
I've never heard the Rienzi, but I have heard the Finn, Fidelio Encore, Parisfal Oviation, Sarastro, and Lohengrin II. The consensus at this shop that I visit is that Verity begins at the Fidelio Encore, and I agree. You get some signature sound at the entry level but Verity does what it does best at the mid to higher end of the spectrum.
I've moved away from Verity with my speaker change to the JMR Emeraude but will continue to enjoy all that the Verity line has to offer.
Congratulations on finding a great speaker!
