I just got new headphones and the Firebox's headphone amp isn't too great for high impedance cans..any ideas on how I could connect it to a headphone amp without putting another op amp in the way?
I need the main line outs for my monitors and I don't have any mixer or routing device between the Firebox and amp with a non variable output.
The only thing I can think of is to add a line out to the amp, but I'd rather not.
  You believe in the users?
Yeah, sure. If I don't have a user, then who wrote me? |

No, and that isn't at all my problem. Keep the discussion in your thread, I was just about to post there.

75-150 ohms is a generally a better range for sound card headphone amps. |

Ok..what are you saying?
I know that's usually a better range, so I built a headphone amp. It was just a connection problem. 
Depends on their sensitivity too..when I had the K 701's, they were around 60 ohms but still extremely inefficient, and the Firebox definitely couldn't have driven them.

Ethereal, I just did what you suggested. I had already had the software installed but never needed to use it, so I didn't know that I could do that. I just routed the headphone out to another line out. Just a temporary fix until I can tweak my DAC a bit more and add a line out..

Very true.
I have read about others getting the firebox and then having to change headphones. |
