Tdacash,
I have not heard the D2 but I ran the updates past TRL and they said to just send them the D1. They did not feel the upgrades added very much value to the sound and that the JFET output might actually be a step backward.
BTW - they said the D1 caps tested very well and they were puzzled why Vlad went with the Auricaps. Overall they were very impressed with the stock D1 which they said was one of the best DACs to come through their shop for mods. Talk to Paul Weitzel and he can advise you more on this, or feel free to email me and perhaps I can help more.
