Actually, I don't think it is simple at all. Yes, the issue with Channel Classics comes from rendering into individual tracks, but I believe the actual issue that causes those ticks and pops is the same as what causes them in realtime bitstreaming. Has to do with time/clocking, as far as I know. I am definitely open to correction...
I also don't think the guys at Merging on the pro side or the guys on the consumer side, such as iFi are unaware of these small issues or annoyances. I do think that DSD presents some unique challenges that aren't as simple to solve. Do I know this? No. But I do believe this, based on the various things I have read over the years, and also based on my conversations with Thorsten at AMR/iFi, whom I respect as much as anyone when it comes to keen insight into all things audio...
I imagine there may be ways to work around it, and it would not surprise me at all if the software guys at iFi come up with some kind of 'solution' to a problem that really isn't of their own making. Reminds me of the USB 3.0 bug from a few months ago. The bug wasn't an iFi problem. It was literally a programming error hard coded by Intel themselves, and Intel was not going to fix things anytime soon, since it affected, well, statistically speaking, no one. But after I am sure growing tired of hearing people complain about a bug that wasn't their own, iFi went out and rewrote code to compensate for Intel's error.
I do believe a lot of these DSD bitstream issues may more readily be solved on the player side. Jriver, Pure Music, etc. John' post is a good example of how different Jriver builds give quite different results.
DSD can sound quite lovely. As a matter of fact, I believe that the very best sounding recordings in my collection are pure DSD recordings by Polyhymnia for Pentatone. There is just a certain something special that is difficult to describe. I personally will deal with a little inconvenience for that kind of playback experience. But I totally understand why some may not feel the same.
