I would love some advice from the experts here on the following - it is time to upgrade my current system (B&W CDM1 speakers, Luxman A383 reference amp, Luxman CD player) as my CD player is at then end of its life. I have a preference to go to a fully digital system and have read some of the reviews on this website around the Sonos and alternative systems. I really like the operational flexibility of the Sonos system and was wondering wheter that box is good enough to drive a decent DAC, which I could feed into my current amp+speakers. Obviously the CD's would be converted to lossless format on a seperate HDD. Can you recommend a DAC that would be suitable for this? Or does it not make sense to do this without upgrading the amp as well?
