Choosing sampling rate with Blu Ray Audio discs

[BruceB]

Not sure why, have you asked Sony?

Audibly you're getting everything....as far as 2ch goes.

To flip the question around the other way, if I already have 24-bit 192kHz in hand, is there a disadvantage in playing it back at that resolution and rate? Is it desirable for the player to downsample what's on the disc before handing it off to the DAC?
