Ones and Zeros to DAC 2017-12-02 22:50:00 This must be covered on this site somewhere, but I can't find it; if so please direct me to the relevant discussion(s).I play most of my recorded music, mainly FLAC, through my Galaxy phone to a Google Chromecast Audio dongle, connected to a DAC using the optical Chromecast output; occasionally I play a FLAC from a netbook via its USB output to the DAC. Other home listening is from a Cambridge Audio DAB tuner via its optical output to the DAC.FLACs ripped from CDs, lately, via a portable DVD player (I no longer have a dedicated CD player) connected to the netbook; FLAC files copied to the phone.So in each case it is ones and zeros reaching the DAC just via different routes. Wired USB (netbook), wired optical (DAB) and wifi (phone to Chromecast).I have tried various A/B testing to see if I could hear any differences between the the USB and Chromecast options. To be honest I don't think I really can. But I soon got bored with testing and returned to listening to one or the other method; so is has not been exhaustive testing.So my question is there a consensus on just sending ones and zeros to the DAC, by what ever method, is good enough or is one better than another?
