Constant sound pressure level device
What would you think of a USB DAC/amp, like a DAC1 USB or better, combined with audio player software that could automatically set the volume of the DAC/amp to a specified SPL (rms, peak, etc.)? Of course, the software would require the user to tell it what headphones were being used, and...- Axcelon

Portable rig for driving DT880 600 Ohm
Right now my DT880 600 Ohm'ers sound best driven by the wonderfully overpowered Presonus Firebox, which is sold as a recording interface. I have hooked it up to my Predator and D10, and I notice a clear difference. I am wondering if they need to be broken in with the 600 Ohm load? My...- Axcelon

E-MU 0404 USB Mic-Input Repair and Headphone Channel Gain Adjustment
I recently purchased a second hand EMU 0404 USB, and upon installing the drivers and hooking it up discovered that the mic inputs of my non-returnable device aren't what I wanted. One is blown and produces a ticking sound, the other is so quiet that I get a SNR of 10 at best with the input's...- Axcelon
