So, I recently started my headphone journey and picked up a bunch of headphones to try. I haven't been quite happy with any of them, so I keep upping my headphone budget. I never thought I'd fork out for a HE-500, but, in my desperate attempt to end my headphone journey, so I can use my time more effectively, I shelled out hoping to end my journey.
I got an AC filter/distributor->dac->tube amp->tube preamp with power cords and wires hanging off my desk and shelf at the moment and think it might be potential hazard for when my baby is old enough to crawl and/or walk around.
I also have an Audioengine D3, an USB bus powered DAC, that I use at work powering a set of JVC HAFXT90 which sounds really good. If the D3 can power the HE-500 effectively, the problem solved, but I am very doubtful that it can. It could barely power up the Beyer DT880 600ohm and the DT880's potential is hindered by the lesser amp/dac.
However, if I can get away with an USB bus powered DAC/Amp for the HE-500, I think my desktop will be infinitely cleaner and safer as the desktop will only consist of a Win8 tablet and the USB DAC. But, what are some DACs are there that can both be powered by USB bus and still make the HE-500 sound good?
Probably a fruitless search but might be interesting. Gimme some ideas.
