Thanks to the many positive impressions in this thread I ordered the Polaris for my HD600.
I have one question. Do I need to disconnect the headphones before powering up (or down) the amp to prevent damage or can I just leave them plugged in all the time?

I have never disconnected the headphones (HE400i, HD650) to turn it off. It does not make any strong noise or anything (at least mine doesn't).

I bought one of these today for my HD600 & HD700. This is my first upgrade from my original Fiio e10. Can't wait to share impressions!
Great amp. I'm using mine right now. I don't think you will be disappointed.

I just murdered my wallet and picked up an Elear that's coming in tomorrow. Anyone have any experience with the Polaris and Elear? Or will I have to try and write down my extremely vague and confused impressions?

I did not expect the adjustable settings to make nearly as much of a difference as they do. At first I was like "the extension seems a bit better, some more treble... meh..." Then I decided to play with the tabs a bit. Went from Low G to Mid G, and the difference was far more life all around! I am impressed so far. This is not just another one trick pony!
Also, different headphones respond much differently.

Bring your input impedance up a notch with the 600's as well. I find Mid R with Mid G to do the trick.
I can say with pleasure that I have never heard such sound before in my life. Such clarity and depth. Using my Beyer DT 990 right now, and the Polaris right away tames the treble very well. Not only that, it extends the bass deep down. Unlike before when I heard only a veiled bass, now the bass is more punchy and clearer. Having the settings at High BW, Mid G, and Mid R.
Looks like many more listening hours await!

Something odd I have noticed in the past few days: My less expensive headphones sound as if they gain more from this amp than more expensive. Ex: HD558 gained a significant amount of clairty, Bass tightened up on the Monoprice 8323, smoothed out the KSC75 a bit, and so on...
