For me, Unless you are fine with ugrading, I’d avoid buying a pre/integrated with a DAC Built in. Sure you can always bypass, however, in years time you will hear about the latest and greatest DAC and then you’ll be back to two units again. I'd keep the LUXMan or go with another dedicated PRE without digital, then upgrade your dac as you see fit.
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?
