Exactly. Many also think the E17 is not worthy of being paired with the Q701 either, but I think it does an excellent job, especially if you aren't a loud listener.
I couldn't disagree more! While the E17 may not be rated to drive 250 - 600 ohm cans, it certainly surprised me when I tried it with my new HD800s. I don't really have a choice right now as I'm on vacation and only brought the E17 with me. It was that or use my iPhone or MacBook Pro outputs on their own. Each persons ears play a big part in what we hear so what's acceptable to me may not be to you.
