Different equipment, but I have found the combination of a tube preamp, in my case the Rogue Audio RP-7, and solid state power amps, Odyssey Kismet monobloc (in Khartago cases), driving my Fyne F-702s to be superior to a tube preamp/tube power amp combination. The improvement was immediately noticeable and significant, in terms of resolution, sound stage, and instrument/voice tonal qualities.
Happy listening!
