Does the streamer effect sound quality

@ghdprentice  The TOSLINK optical link was specifically designed for 2-channel audio for CD quality bandwidth.  The interface components at either end are of mature design, not a "throw in" item of questionable design. Optical cables are immune to EMI/RFI and ground loop problems. Optical can have jitter on the order of a few nano-seconds.  Any decent DAC will easily deal with that. 

SPDIF can suffer EMI/RFI and ground loop issues. A clock signal is embedded that has to be recovered.  Potential jitter is data dependent and there are low pass and high pass filtering effects to deal with.

Properly implemented either TOSLINK or SPDIF is more than adequate for high quality serious audio.    

I went from the very good Bluesound Vault 2i  to an Aurender N200 and it was a huge difference.     Great machine. 

But CDs sound better than any high end streamer right?  Assuming the same DAC.

I'm not so sure about that.   There is a lot of 24/96 and higher material out there.   The other night I was playing Pete Yorn's 2003 The Day I Forgot on vinyl.   It sounded really good.   Just for S&G I played the same album on Qobuz and it sounded pretty damn good.     It told me one thing , I need a better cartridge......
