Howdy. I need to buy a new set of headphones (my Grado SR125s seem to have lost input to the right phone) for my PC recording activities, and in doing some research, I saw mention in some reviews of the need for a headphone amplifier to really get the most out of certain headphones. I'm using a PreSonus Audiobox USB 2X2 recording system for both my instrument inputs and audio outs, and I'm wondering if the device has a headphone amplifier. I'm fairly certain that it does not, based on the fact that on the PreSonus site they make reference to the mic pre-amp, but for the headphone out they only list the following:


Type ¼" TRS Active Stereo
Maximum Output 60 mW/Ch @ 60Ω Load
Frequency Response (±1.0 dB) 20 Hz - 30 kHz


But, since I'm still pretty new to the whole thing, I figured I'd ask and see if anyone knows the answer to this question. If it helps, the site for the AudioBox is here:


Thanks in advance for any help anyone can provide.
