Thanks for the detailed explaination @sheldaze, I haven't been following along as well as I should have been over the years and I feel caught up now
Agreed after the edit my issues weren't as intractable! It sounds like my best bet is to get the upgrades done; I can take some kind of sick comfort that it would cost me ~$600 (not ~$200) more to just buy the Gumby outright. I trust that you guys aren't all deluded and there is a genuine leap in transparency (so there's no need to A/B), so the upgrade makes the most sense. With my new (to me) amp coming, this will need to happen sooner than later.
And yes I knew this going in, it's fantastic that I can upgrade my DSG to a Gumby; I wouldn't have it any other way. But ~$675 is almost like buying a whole new DAC! So please forgive the rant. I do have a couple more questions. You alluded to maybe never on USB3 for Gungnir, but with my luck the moment I get it back it will become available. And because I'm planning on A/B'ing a couple of good Spdif converters (and have always used one in my DSG), the USB is mostly unused anyways. So it may make sense to wait for the USB3 and do it myself if it ever happens.
Do you guys see another upgrade path coming sooner than later for the Gungnir? For example do you think they might be inclined to combine the multibit technology with the 4490 chipset, or is that not technically feasible? The other thing I was wondering is if the warranty gets any kind of re-set by Schiit after they are done doing the upgrade, since I've had my DSG since the first year of release it's getting close to expiring.
