Thanks gentlemen for your responses.
Mahler, I have B&W 802d3's so your impressions regarding DAC's employed with the 803d3's are particularly useful.
Nonoise and Melm, I am still not convinced that the major difference in
the sound of different DAC's is their implementation. I owned a Luxman DA-06 for a few months, rued the loss of detail in folds of velvet, replaced it with the Bryston, find the Bryston still lacking in dissection of dense orchestral texture. So is the audible 'grain' of the Oppo 105's Sabre DAC implementation just 'grain', or is it a more accurate rendition of orchestral texture and the bow-on-string violin sound ? 'Commercial' reviews notwithstanding, I find it hard to believe that the Mytek, a unit with multiple functions and retailing for $2200, employs other than cheap components and offers implementation of the newest SABRE chips comparable or superior to, for example (& which I would love to audition), the Mark Levinson 585 or 526 units.
And if, like myself, some of you have 'discovered' orchestral and operatic audio/video recordings on blu ray, you may agree that the Oppo's audio decoding of blu ray is quite good....not as good as the Bryston's decoding (it is hard to persuade the Oppo to through-put the digital blu ray audio signal to the Bryston when it is sending the video signal elsewhere).
Loudspeakers offering more accurate rendition of orchestral music is another subject, one I'd like to broach in another 'thread'.
