I took a look at the manual for the PL DAC, which has a more complete set of specifications than the website page provides. The one thing that struck me is that it has a rather high output impedance of 2.7K.
Apparently its outputs are transformer coupled, so the impedance probably doesn’t rise much above that value at any audible frequency (as it probably would if the outputs were capacitor coupled). But still, before purchasing it for use with a preamp or integrated amp having a low input impedance, e.g. less than 20K or so, I would check with PL about the advisability of doing that.
