Cable question

I have used toslink with  very good results on a Bluesound streamer.   Enough?

No. 

I say no, so long as both cables are working correctly and not dropping bits.   Digital is all 1s and 0s so there is no .98 vs .99 performance.   Generally those who tout improved digital performance are trying to sell something and hope you'll convince yourself you can hear a difference. That said, there are people I respect who disagree with me so I continue to keep an open mind on this issue.

Optical does require some data management on both ends so you can lose some bits there and I have had optical systems that I thought didn't sound as good.  Maybe it's the conversion.

I use USB.

The answer to the question is like most things with audio - it depends on the gear that's sending and receiving the data.

Whenever I have the option, I try both. I don't think I've ever never not preferred coaxial to optical in a comparison. My Bluesound Node 2i was far superior via coaxial into my Marantz SA-10.

Optical cables are cheap but there are more expensive coaxial cable options. My favorite coax is actually a Blue Jeans Cable coax that is reasonably priced. I have coaxial cables that are magnitudes greater in price and I prefer the Blue Jeans for $30 or whatever it was. I don't understand why but different coax cables altered the sound I heard.

I'm using optical just because that's what i had laying around. I was also thinking of the BJC coax. I will try that. Thanks.
