I believe we will get the most step up from the DD, in the Renderer V2. I hope to share soon here my findings. Although, if you have a Quad Rate USB, it may be a pleaser surprise. This module won’t suck the power from the server anymore, if I understood Johnathan’s explanation correctly, but from the DD PSU. Of course I will try the Pro USB through the DD but I’m not to much confident that it will make a difference. I may be wrong.
Regarding the server, pardon my honesty, but you‘re not taking the full potential of your DAC. Hope you can demo the Extreme or just dive in, like I did, coming from a Pink Faun. With all the step ups Taiko will offer along this year it will be un audiophile’s dream, so our pockets can support it…
