Both of these are at my $250 budget, with the Asgard actually going to cost me more at $280 because of California tax.
I don't mind having to mess with tubes for the Little dot, and they'll give me something good to "photograph" when I'm bored.
Admittedly, none of my headphones are hard to drive, with the hardest probably being my Fostex T50RP.
Here is my current setup.
Source: Macbook Air (this could be variable, but for now it's the MBA)
DAC: FiiO E10
Headphones: Sennheiser HD598, Brainwavz HM5 (Similar to Fischer Audio FA-003), and Fostex T50RP.
I listen to pretty much everything, but the bulk of it is probably stuff like Dave Matthews Band, Jack Johnson, Weezer, Queen, Boston, Moby, Miles Davis, Female Jazz vocals...
