Re; Dynamics, Class D vs tubes…

Bill Stevenson,  Thank for your experiment and conclusion.  

Many amplifiers, regardless of class, require some increased volume setting to properly drive certain speakers.  It is usually the interaction between an amplifier and the speakers themselves that determine if the “dynamics” at lower volume fulfill your specific desires.  Do not go down the tube vs ss, class AB vs class D thinking there is a simplistic formula that will work for your hypothetical speaker. I wish it was that simple as it would have saved a lot of time and money (but then what would have been the fun in that…)  

I have a bunch of tube amps, I'm a tube amp guy. With my Tekton Perfect Set 2-12s my best demo was with a Rogue Sphinx V3 (class D with tube front end}. It took the class D amp to get the loudspeakers thumping. Big sound, big impact. 

West Coast Audiophile,  Enjoy!  I have given the specs of my speakers, the class D Amps I plan to audition are the new X mono blocks from Peachtree.  
Rounding out the field…Shindo Aurieges pre, Quicksilver V4 monos, KEF Reference 1 meta, Basis 1400 TT w/ Vector V4 arm + Benz Ruby OA low output with step up. ICs are Shindo, Spk cabling The Chord Company.  Vinshine Tia Hang.  
Please go ahead impress me now with your answer since you have my equipment list.
