I am researching headphones and amps and wondering what the best way it is to setup the connection between the audio system and the headphones.
My audio system is about 15 feet from my listening chair. My preamp has both analog and digital outputs. I can think of several different conneciton options:
1) Place headphone amp by audio system and run a long headphone cable to listening chair. Connection from preamp to headphone amp with an analog line level cable.
2) Same as #1, but connection between preamp and headphone amp via digital cable (assumes headphone amp has build in DAC).
3) Place headphone amp by listening chair and run long line level cable from preamp to headphone amp.
4) Same as #3, but connection between preamp and headphone amp via digital cable (assumes headphone amp has build in DAC).
Which connection would give this best sound?
Another question is should the volume level be controlled by the preamp or the headphone amp?
Thanks in advance.
