It sounds like you will like the Ayre in terms of amplification, and the real question is whether the built-in streamer/DAC will be an acceptable replacement for the Pi/Mytek. Are you using a streamer HAT on the Pi or just native USB? If the latter, you might be okay if the DAC is to your liking. It sounds like Ayre has a good reputation with their DACs as well, so not too much risk there. I have a Pi/Allo/Roon streamer that will require a worthy piece of gear to replace it.
Integrateds: Luxman vs. Ayre?
This shootout is between the Luxman 507x and Ayre EX-8 2.0
Currently I own a Luxman 507x. Rather happy with it... but...
I use a separate streamer (Pi/Roon) and DAC (Mytek Brooklyn) for music and an external Anthem processor to feed it HT 2 channel.
My thinking is, the EX-8 would let me eliminate the DAC/streamer AND it has a separate sub out.
The issue is I've not heard the Ayre integrated, only the separates and I really like them, though they do seem to have a distinct sound to them.
Thoughts?
