I agree, M1 sounds more spacious and with better separation of instruments than mini 2018.Using an M1 Mac mini as a music server, replacing a 2010 model. Even stock - using iTunes though a Aurrender spdif converter to a Naim dac - the M1sounds audibly better than the old one running Audirvana.
I am using Amarra Luxe.
M1 took the place of the server, instead of mini 2018.
