Or is that just your experience across the board with players?
Follow Ups:
Monarchy Audio M24. Uses BB PCM63 true 20bit DAC and DF1704 8x oversampling digifilter. Also, passive IV conversion and no opamps. Output through zero feedback SRPP tube stage. No transistors in the analog section! Wonderful sound.
I have a Sony XA777ES SACD/CD player. Perhaps I should at least look into it.
"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.
