Remove the caps lock and I will answer your questions. Right now you are shouting at your fellow Head-Fiers.

What's wrong with you?

 

This is a forum, not a Republican debate where you must talk over others (I jest). 


Just calm down, the caps aren't going to help your case.

For me, it opened up after about 50 hours and didnt seem to change any more beyond about 80 hours. Some would say that's placebo, but I enjoyed the amp a lot more after 50 hours.

You will definitely notice the jump in power. The P4 is effortless, and you will rarely need more than '9-10am' on the volume dial from a decent source into reasonably easy to drive cans. Just dont expect to be driving big orthos from HiFiMan with a portable amp.

Spend the money on headphones. The P4 will pair well with your Cowon, but if you dont need an amp, dont get one.

Well,now you had order the P4,and I think you will have a lot of fun with this amp,especially for the rolling off.

AD797+BUF604 WB(the BUF634 with 200ohm impedance)+solid-state buf(the tallest opamp of all iBasso paired with P4,you can put this on the virtual ground,where is near the battery.)+TLE2141(put this on output ground,near the headphone jack.)

This combo is a suitable pairing if you just use the opamp iBasso gave you.And this picture might help you when you first time do the rolling off.

Just take the time to appreciate the stock sound sig of the P4 before you start rolling opamps, and research advice from HiFlight and Spud Harris before rushing out to get the AD797 - that silicon isnt for everyone.
