"Or is that just your experience across the board with players?"Exactly. Whenever I listen to converters that use asynchronous sample-rate conversion on a high-resolution home audio system, there is a band of noise of constant spectrum cast in the high-frequency components of the converted audio signal. At first, it is perceived as detail, but after a while, I notice a constant signature to the HF, and I ultimately get fixated on this artifact. It's a symptom that I've noticed with ASRC, and it becomes more-apparent when I later listen to a non-ASRC DAC, where this artifact is noticeably absent.
I later deduced technically that ASRC transforms jitter at the input to noise at the output (Item 3 in the link), and while I have not proven this to be what I actually heard, the fact that jitter has a spectrum would cause the transformed noise to have one as well. Which is consistent with what I heard.
