Hey guys, I just bought a pair of ad700's, which I think sound great, and I am trying to plug them into the tube amp I have. Right now I have my computer sound card(xfi titanium) connected to my tube preamp which is connected to a tube poweramp and then connected to speakers. The problem is the amp has no headphone jack and I would like to connect my headphones to the amp and still have the sound going through the tube amp. What is the best way to do this? Is there an external headphone jack I can get or do I need a DAC? I have a firepod and I actually want to send back my sound card and use the firepod as a dac into the tube poweramp. It does have its own headphone jack but I dont think I would be getting the tone from the poweramp but from the firepod and I do not know if that would be good. Any help is appreciated!! thank you!
