Thanks George.
The jump from 32-523 you made is probably the closest. I did hear the 523 when demoing the 536s (against my 532h) and sound was good.
I listen to vinyl (LP12/Ekos 2/Kandid) mostly so am considering a separate phono stage (Vitus/Whest or similar) but the box count would increase yet again so a one-box line stage/pre would free a shelf!
Never heard BAT so can't compare but thank you for the recommendation, although I see it is a two box design without a phono stage so not a box count friendly combo!
