I used one of the old Headroom Ultimate Desktop Amps with the external power supply. These have fallen out of favor around here. It was a really nice dac/amp combo and a sweet pair with the D7000. Every once in a while one pops up at a decent price.
Dead Thread, but I would still like to add a link to another thread on this forum that seems to be disclosing this topic quite extensively:
Thanks for the link -- I will add to this historic thread that they sound amazing fed from vintage speaker amps. That bass with the tone controls and loudness circuits sounds fantastic.
