Doesn't seem right to me. Or have I completely misunderstood the interaction between player & DAC? No. Anything at lower rates is upsampled. If the DAC accepts 24/192 it (or 24/176.4) bypasses the internal PCM upsampling. I'm guessing the DAC then uses sigma-delta modulation to megahertz rates before final conversion to analog.

So really it doesn't matter how low I set the A+ sample rate it will get the 24/192 treatment when it reaches the DAC. I guess the same applies if my music is of higher (than 24/192) sample rates, it will get downsampled to the Explorers maximum. My concern was that too much processing might cause SQ problems. You can think of the situation with lower resolution files/rips as having your choice of A+ upsampling or the DAC's internal upsampling, whichever you prefer.
