Recommendations for Blu-ray Player

An Oppo BDP-105 is not a " high end digital source".  It's a little above entry level, and a great multi-purpose unit in its time, but it's long in the tooth.  The DAC is easily surpassed, your streaming options are limited, it's not a great CD player, doesn't support 4K, doesn't do Atmos, not to mention, good luck getting support on one.  Add to that, people are asking ridiculous prices for them, and it just isn't a good recommendation.  I still have one in my bedroom, but I rarely ever use it and I only use the BDP-203 in my main system for movies.

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

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 did not start the discussion.
