Hi EeePee. With the DAC level at 0, using the HD800 on a balanced RS-OCC cable from Double Helix, I had enough volume for my ears at 2. Now, I learned when I visited Ken Ball's headphone store 32 Ohms in Portland last year, that I use a MUCH lower volume setting than almost everyone else (esp younger folks), so you might set it at 2.5 or so. Also, the RS cable has a very noticeably lower resistance than the stock cable.
I will try the HD800 using the stock cable on the 1/4" TRS output and let you know.
