Again, I very much appreciate the feedback I have been given. I am in process of researching the speakers suggested. I find myself thinking that I initiated this post somewhat in haste and maybe should has given it more thought.
I Currently have 3 amplifiers in use in this system (have another system for the living room). They are: Pass XA25, Aric Audio Transcend PP tube; and a PS Audio S300.
The Pass and Aric amps are in use with the Fritz speakers. The Pass and the PS Audio are used with my Magnapan LRS+ speakers. The PS amp provides greater power with far less heat for summer months.
I have been toying with the purchase of Aric's KT88 SET amp provides from 7 to ~ 20 wpc depending on tube and mode used. I have driven the Fritz with the Transcend PP rated at 16wpc using EL34 tubes in triode mode quite satisfactorily. I have been in contact with Aric regarding using this SET amp with the Fritz. I totally agree with @scotandholly that the Fritz. are hard to beat, even at 2X their price.
My thinking is that there are not many speakers below 10K in price that would fit my room, have the flat 8ohm impedance and modest swing in phase angle of the Fritz Carbon7, and better their true 89dB sensitivity by 3dB.
Thanks again for your attention towards my quest.
