I have a pair of Stax SR-7 electrostatic headphones "earspeakers". They have been out of service for a few years in my main sound room, I'm not even certain that they are good as new but I seized on the idea of using these once great headphones for computer audio. The question I have is, how do I properly drive them? I do have a BK ST-140 amplifier available but I need a DAC and a headphone amp/pre-amp.
The Audioquest Dragonfly is one possibility I've been considering but for my situation I'm not sure it would be usable. I am now looking at the NuForce Icon HDP headphone amp/DAC and wondering if this would be a worthy investment or perhaps I should give up on the Stax concept and invest the money in new headphones more appropriate for computer audio.
Anyway, I'd love to use these headphones again but it's been a few years since they've been in action. Using two items I already have, the BK amp and the Stax does have a good feel however.
Any advice will be greatly appreciated.
