Headphoneus Supremus
To be honest I don't blame people for being put off by computer transports and music servers, firstly because not everyone is computer savvy, but also because in my opinion computer based hifi audio is only in it's infancy, it has quite a distance to go and lot of hurdles still to overcome.
For the HE-6 I think most people are not keen on buying an amplifier to power just one headphone, at least this is what put me off at first. Then again the HD800 is no less specific in its requirements for an amplifier, as are STAX.
Simple problem to solve. Get rid of your other headphones.
