Was listening to my old Eximus DP1 at my brother in laws on Monday - sounding really good and it’s so beautifully made.
He just uses it as a dac connected to an Auralic Mini (not i2s) but It also has a seriously good analogue volume control plus an analogue input for your turntable so just add a power amp.
No idea if it can connect to a Raspberry Pi I’m afraid.
