Ok, I’ll bite. I have a Pi and a Mojo. It punches way beyond it’s weight, and with Volumio as an operating system it’s easy to set up. The most challenging thing is creating the card with the operating system on. If anyone wants it doing for them I’m happy to do it, just post me your card!
Sound wise it’s fabulous. I mostly use it to play Qobuz, but it will happily read network drives. I also chose to hardwire it, I found it slightly more reliable. If I ever didn’t use it for a week or two a period of resetting all and sundry was necessary. It also removed a little noise from the system. A useful improvement for me might be to install a hat and use optical out.
I seriously think that you’d be hard pressed to massively improve on the Mojo/Pi combination without getting into seriously big bucks. I might try a 2qute sometime and reinstall the passive pre I have around. I’m more tempted though to buy a Leak Stereo 20 or otherwise upgrade the amp. Then I could always build some big boxes for the Tannoy 8” drivers I’ve got in the i8s.
Don’t think a pi is hard. Clip it into it’s case, slide in the memory card and turn it on. Volumio creates it’s own local network, you can then connect to that Install your own wireless, then it’s accessible by any device via your router. Takes 10 minutes.
