Sry for bumping but since i didnt get an answer i believe that it wont be any problem regarding amp on prelude.
I have finally decided to buy K-701 since Q-701 dont seem to worth the extra 100e just for gaming and some movies.
I am also going to use O2 Headphone Amp to drive the headphones all that connected to my prelude. I was thinking about the Fiio E9K but i cant find it in any logical price in europe. I am also going to give a try to this mic, its very cheap and has some good ratings.
Any hints are welcome:wink_face:
Double-amping usually works out ok, I have the headphone-out port of my soundcard plugged into a tube amp, then my Q701s into that, and I don't get any hiss, scratching, or other noticeable distortions. Ideally I'd just use an analogue line-out signal from my soundcard to my amp, that's not an option for me but might be an option for you. Use the RCA jacks to connect to the amp, if your card has them.
FWIRead the O2 is a slightly better amp than the E9 anyway.
