Just a suggestion because I am not familiar with your speakers.
I understand that you want a refined poweful sound. Older Rowland Concentra and Concentra II, and older Gryphons are hard to find but might do that for you. Gryphon currently has no distributor in the US, I think.
New Redgum from Australia could be quite good too, most likely not as refined as either Rowland or Gryphon, though.
I use old Redgum 120 integrated with warm sounding Michael Green Audio speakers, 89db, and the sound is excellent, quite nice and very dynamic. My Nottingham turntable is happy enough with this combination.
I am sure there are other choices.
