Just out of curiosity, what's the appeal of DSD for you?
I digitized over 1,000 sbd cassette masters from the GD vault using various hardware. I used the mini me, 744 and Tascam da-3000. I found that the DSD is the only format that captures the warmth of analog while still keeping the clarity of digital. There were some tapes that lost low end at 24/192 but kept it in DSD. It’s like digital vinyl. I’ve never heard anything like it. Stunningly amazing. I bought two Tascams and run them as a 4-track. DSD keeps the depth, clarity, warmth and definition that vinyl brings.
I would love to field test one sometime.
I recorded in DSD with a D100 for awhile and absolutely loved it. I felt the same as you about the results I was getting...but for every post I made expressing my enjoyment of DSD, someone that didn't have access to listen to my files would accuse me of buying snake oil. Like you, I know what I hear.
In the end through, I gave up in frustration of the unavailability of software that didn't send the DSD files through a PCM conversion. Even so, listening directly on the D100 to my DSD captures was sublime.
If this situation changes I'll quickly jump back into DSD.
