i go with my h10 on SRS-off, equalizer off though. just pure off the recording
i dont like "enhanced" effects as they sound uneven across different recordings.
some people had asked me as well.. what source i am using on the mover with a computer.. why am i using a cheapo creative X-fi usb sound card for a couple of expensive headphones.. and further degrading the sound with a level attenuator etc
but i dont use the headphone out. i use the line-out and the attenuator to adjust.
the headphone out is too weak. using the line out it sounds good to me at least
dont need an amp
