Recommendations for Blu-ray Player

Think I can find what I'm looking for if I relent on the coax output, and use the optical input to miniDSP4x10HD instead.

I don't remember precisely why SPDIF optical is not as good as SPDIF coax - I just remember reading several comments where AES and optical were shunned when compared to coax digital signal quality.

Is there an inherent digital limitation with optical, or is it a conversion/generation loss issue?

The problem with optical toslink is that the light emitting diodes (LED) cannot light up fast enough to produce a perfect square wave.  The wave comes out almost curvy (almost like an analog sine wave).  You also have potential problems with the light receiver.  As far as how this affects sound quality, I can't really say. But I have compared toslink to COAX and COAX is always better as long as you have a good digital cable.

I thought this was Audiogon not Videogon bkeske....???

I did not start the discussion.

i am streaming from a Oppo 103 into an external DAC Tidal hi-res. sounds very very good.  however not sure if a dedicated streamer like an Auralic or Bluesound ect.  would sound better going into a DAC?
