I would really like to see this multitrack DSD stuff get more accessible. I would build a mad crazy mixing board with LCR pan switches and Davelizers for EQs or some such thing, and start making music without editing (or with whatever minimal editing it has) and without plugins and DAW trickery. I'd just run with it. I'd be so happy, it'd be such fun.
Stands to reason I would like it. Back in the day when I was checking out my audio proficiencies and inadequacies on double blind tests (using incredibly poor equipment compared to what I've got now), I found that I had no trouble sorting out resolution issues (hearing lossy audio like 320K double-blind against PCM, using a castanet sample by Arny Kreuger) but I was positively hopeless about hearing wow and flutter. I just didn't hear that stuff at all.
Ever since, I've had every sympathy for people who turned to CDs because they couldn't stand pitch issues: I proved to my satisfaction that I'm way more tolerant of those, therefore if someone was much more bothered by that stuff they would never, ever like typical analog playback (perhaps not even physical tape machines, which also flutter). However, I've never had anyone cut me much slack for preferring high word lengths in digital, schemes like DSD or analog recording. Seems a pity.
Maybe that means eventually I'll be able to buy a once-valuable multichannel DSD rig, or even a dedicated DSD rig of that nature. Since it's just digital and software and the ability to pump a lot of data over a buss, I can't see such a thing remaining in the tens of thousands of dollars, unless it's for scarcity value alone. I'd like to see a little box with basic multichannel punch-in capabilities and multiple analog ins and outs.
In fairness, if you don't mess with the recording ITB it's awful easy to have much of that with about $1500 worth of modern converters. There's really no practical reason I should be dissatisfied with my MOTU 16a, other than 'it doesn't like to run high sample rates for long periods' (if it sits around idle at 96K for hours, it ends up needing to be reset: never even tried letting it sit around at 192K for hours seeing intermittent use)
I'd quite like to have a '16 TRS in, 16 TRS out, all DSD' box to play with, even if I had to run a dedicated program for the 'tape transport' aspect and not a normal DAW. I'm getting into Renoise lately which is most atypical. Not sure if Thunderbolt can handle 32 IO channels of DSD, but if it can sort of do that many 24/192K it seems not impossible (haven't done the math)
