Which headphone amp should I get?

[MusicDirector]

I've decided to get a headphone amp for my vintage system. I don't know that I need one with my new AVR as it has a feature or two with the headphone jack that I want to check out and if I use an external headphone amp it will bypass those features. (If I don't dig them of course, then all bets are off and I can use an ext can amp, however, I do not see a way of hooking up an external headphone amp to my big system). My headphones are Sennhiser HD518s

I'm trying to decide which one to get. I'm not sure I want tube (I know next to nothing about them), but included them anyway.
My choices are:
Fiio E17 Alpen
Fiio E12 Mont Blanc
Fiio E09K
Fiio E11
NuForce ICON UDA2
ART Headamp 4
Bravo V1 Valve Class A w/ Russian EH6922 Tube
Bravo V2 Class A 12 AU7
Behringer Amp800
Schiit Magni
Schiit Vali

What say ye?

There are waaaay too many choices out there. I own Senn HD800s and I use an Auralic Taurus. IMHO its a good match, but to be honest haven't heard a lot of alternatives. If I were in your shoes, I'd spend some time on Head-Fi.org - Headphone forums and reviews for audiophiles. Of what you've got listed above I know Schit is making hot products.

Yeah, too many choices, I agree. As it's only headphones ($120 headphones at that, not fabrige eggs) and only very occasionally used, I don't want to go through headphone forums for audiophiles.
I think I have come to the conclusion that perhaps the correct answer is "None of the above" at this time. (Or perhaps just get a Schiit and be done. I'm leaning more towards continuing to wait on it).

I really love my Mc on Mc headphone setup... the amp is McIntosh's best headphone amp circuit and the headphones are their one and only (so no difficult choice there )

Opps... sorry, didn't read the budget range before my post.... The Mc headphones and amp are quite pricy....
