Well, I did read your other threads but as I said when I spoke with both Kingwa and Magna, they both know the R2R11 is inferior for DSD, apparently FPGA is not there in R2R11 so hence DSD is not as ideal. The average non-classical or jazz listeners may not hear the noise as music may be too loyd. As we may be the only listeners of SHostakovich and Mahler where passages of ppp, you can hear noise, esp at beginning of a track, say a Brahms piano quartet in A that I have, or Tchaikovsky's 6th quiet beginning, then it disappears and then reappears again at end of track, or occasionally reemerge in quiet passages. That is my experience with R2R7. I am not sure if R2R1 still has same issue. It should be much better than R2R11 and can' really hear unless you use headphone or stick your ear next to the speaker. I am also thinking of later getting R2R1 or the R1 for multi-channel DSD files playback but I also hope it won't have the noise as well. It could well be my computer's issue, so I am waiting for my new Macbook and try then. To be sure that R-1 works for you, you may want to send your own files to have them test the unit.I don't want to repeat myself, as we have discussed it very well on that private thread.
I wish, I could spare the Gergiev, Mariinsky Shostakovich Symphony No.:7 with you. It's a wonderful piece of art from both the composer, the artists, and the audio engineering side. If I convert it to PCM on the fly under Foobar 2000, everything is seamless, but native DSD playback is full of glitches and noises. You can recognize this problem mainly on the most piano parts of high DR records - this is why you notice it at the beginning and at the end of the tracks, as they often start with quiet parts -, as low DR records doesn't contain this very-very quiet portion of the music. The aforementioned Shostakovich album contains DR16-DR18 tracks, but At least 30% of my DSD collection suffers from this problem.
Unfortunately on the official website, audio.gd still uses such phrases like "Unique noise process technology will remove any digital artifact", "DSD native" "To avoid the digital artifacts, a uniquely designed noise rejection processing technology is applied."
According to these, If I were a new customer I would believe, there shouldn't be any problem with Native DSD.
Thanks FredA for answering that question.
BTW, I think there is option of using Amanero USB vs F-1 USB, at least from Magna website. Kingwa can fit in F-1 if you ask as well. Magna states Amanero has been giving him problems with DSD. I use F-1 board but also has issue. Others have no issues with Amanero board either. Magna did state that unlikely my F-1 is the issue. Go figure.....! BTW, Magna did test out my files on R2R7 and he reported no issue, so it may well be some issue with my setup. We even contemplated issue with dirty AC power but I use battery from my Macbook....
My guess is R-1 most likely sound much better on DSD256, but may not be 100% issue free
