Are you getting both the E9K & E17? You can run the E9K off integrated motherboard audio (yuck) or a PC sound card if you already have one, some sound cards are actually pretty decent DACs so that's an alternative to the E17...
If you want a portable DAC/amp for laptop use or whatever then the E17 is a nice choice and it pairs nicely with the E9K, but if the E17's portable amp or extra inputs aren't a factor then I think you can get a comparable DAC for much less, or a better desktop one for about the same (either paired with the E9K amp).
Or you could just opt for the E17 by itself, no clue how capable it is with AKGs tho.
