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.

Also I do agree with all that is said about the description of Accuphase vs Luxman for sound. For me personally not a very length decision on which one I would take. The Accuphase E-600 replaced a much more expensive separates combo (Shindo Giscours + Cortese/Haut Brion) for me.
@builder3, Luxman make some really nice gear. But there are much better integrated amps at that price point imho, one example being the Audio Analogue Maestro Anniversary.
@yyzsantabarbara You didn’t specify in what price range you were enquiring, but I assume you mean roughly <$15kUS. Based on my own auditions, I have been impressed with the following amps listed from lowest to highest priced -

- Gold Note IS-1000
- Rowland Continuum S2 (and yes, I never thought i’d say a Class D amp sounded good)
- Audio Analogue Maestro Anniversary
- Boulder 865
- Audia Flight FLS-10
- Vitus RI-101

I recently a-b tested Pass Labs vs Luxman and Accuphase separates, and preferred Accuphase in that shootout. Hence, although I haven’t specifically heard the Accuphase E-650, I’m fairly sure I would prefer it to the Pass and Luxman integrateds.

Re: the Gryphon Diablo 300. I know there is a lot of hysteria on this site, and on Audioshark. And yes it is a good sounding amp, but as I understand it most of their chassis parts are made in Taiwan. To each their own, but personally I would take the Vitus RI-101 over that amp every day of the week.
