I have a Naim Nait 5i-2 and a Naim 5i cd player, both latest models. I also have a sonos ZP90 and ZP110. I am thinkng of buying a DAC to improve sound quality when playing music on my PC via the Sonos. AS I already have a good CD player with, I assume, a good DAC, is it possible to connect the Sonos to the CD player and use the DAC within the supplier ?
