chicolom, have you by any chance compared the Q701 to the K550. I am currently in possession of the K550, but I feel like something is missing. 

 
No, I haven't heard the K550.  I think Katun has heard both...

Great review it helped me out a bit deciding if to grab a DT990 that is on sale right now as I already have a Q701 and from my untrained ears and my current DAC don't think would be much of a noticeable difference/improvement and probably can invest the money in a desktop amp. 
 
Currently I use a mixamp for gaming and have not noticed the need for more amplification but probably because I have not heard the difference.  I usually run the Q701 off an Onkyo receiver or off the PC/PS3.
