- 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.
