Accuphase E470 v. Luxman L509x

I am a long term fan of Japanese gear.
I am considering the Accuphase E470 or the Luxman L509x.
This amp will be running Joseph Audio Perspectives and Salk 12in Subwoofers.
My listening room is 23ft X 22ft with a12ft ceiling.
My musical taste preferences are classic and alternative rock and jazz.
I do not play my music loud.
My current amplifier is a Yamaha S2000.

Any assistance would help, thank you in advance.
