I have the Tritton AX 720's and I think it's time for an upgrade (besides the fact they're falling apart heh). I read Mad Lust Envy's guide and decided to pick up the Koss KSC75's (for all around usage), to save up for the Beyerdynamic DT 990 PRO's, and get the a antlion or that $3 mic listed in the guide. I know those aren't the creme of the crop headphones but I'm sure I'll catch upgrade-itis eventually.
My problem now is I'm having trouble deciding if I can/should use the decoder from the AX 720's and get a sound card for my PC or should I get something like the FiiO E17 USB DAC headphone amplifier so I could use it on my consoles and PC interchangeably.
Any help is appreciated.
