I tried DSD64 (1 bit @ 2.8224MHz) bitstreamed to the X-Sabre with no problems. DSD64 bandwidth (including the additional 8 bit header used to identify it's a DSD stream) ends up as the equivalent of 24bit / 176.4kHz. So I can only assume that the PCM wrapper was running at 24/176, since the DSD64 or DSDx1 light was on the DAC.
To my knowledge, DoP v1.0 (and from its conception) was always able to support DSD64. (8 bit header + 16 bit data @ 176). I mean, it wouldn't make sense for them to support a standard which lacks sufficient bandwidth to embed at least DSDx1, ya?
The only thing I know is that JRiver supports the DoP 1.0 OxFa, 0x05, and older 0xAA marker/header formats which identify the DSD stream embedded in PCM.
Never said JRiver is the end-all solution. My reply was in the context of Q's comment on getting older and not being able or having the inclination to "learn" or I as prefer to call it "F with stuff". "Learning" or "f'ing with stuff" to get things to work gets tiresome when you get older and have other responsibilities. In the sense that time = money, I've found that foobar has been much more expensive.
