@agriculturist,
That's a very good question.
The short answer is system space constraints and the length of my High Fidelity UR or U power cords.
My main rack is full and the Denali 2000T fits very nicely in a small space right next to my main rack, while the Q2 is in a different location.
Given more time to experiment, I'll try running the Dac and Transport out of the Denali and my amp, preamp and Phono out of the Q2.
It's all about mixing and match to see what sounds the best.
I've been experimenting with several differet power cords in my second system, and that's where my time has been spent for a while now.
