Why are you even considering amps with this kind of power for 105db, 8 Ohm speakers. Way over kill and wasting your money on power you will never need. As much as I love Luxman, I think for your laScala’s your current amp will be the winner.
I ran an older Luxman class A amp on my LaScala’s when I had them very nice but the best amp I ever used on them was a 2.5wpc 2A3 SET from Triode labs. I’m thinking the more refined and maybe warmer sounding Accuphase will be the better match for the LaScala’s. Side step to a slight difference is all your going to get IMO.
Interestingly I’m considering upgrading from a Mac system (C2700/MC301 mono's) to Accuphase.
