Same experience. My Esoteric DV-50 can be set to output 24/96, and I have done so, but the manual says it can do it only on discs which permit it. It is hooked up to a digital input on a dCS Purcell, which displays the incoming data stream. On more than 20 DVD-A's, not one of them is outputting more than 48, according to the Purcell. In contrast, when I turn on the upconversion on my other digital source, the Purcell reads 24/96 incoming.
DVD-A player that'll output 24/96 digital signal
I was told on in a post on this forum that a Technics A10 player will output 24/96 through it's digital output. Now somebody who owns one wrote to tell me this wasn't so and said he checked it himself to be sure. Is there any player out there that you can use with an outboard DAC ?
