Thank you for your input.
They were originally Fostex mods werent they? They are custom built with customer drivers now?
Did you ever had the chance to listen to and EQed LCD-X or XC? If yes, how does the "slam" compare?
Yes they are a mod of the Fostex T50RP. It's still the same drivers but the mods are rather extensive and mysterious.
I haven't heard those Audezes but I have the LCD-2 and use lots of EQ to emerge from the darkness, and to boost the bass. Haven't EQed the Argons yet but snare hits have this impact that rattles my teeth. The Argons slam harder than the LCD-2, more noticeable on EDM and hip-hop, and I can probably EQ in some more slam but I'm enjoying them as is right now. Less refined than the LCD-2 but the difference in cost is pretty large.
