Hi guys, I was browsing amazon the other day looking for a good starter open-backed headphone. And because I'm a cheapskate, I found what looks like a promising deal with the AKG K240 studios. Anyway, I was discussing this with some folks on reddit and they recommended the Superlux 668b as well. Both of these cans fall well within my budget (I could actually buy both of them and still be under budget). So, fellow head-fi-ers that have experience with these headphones, what do you suggest? Also, I am not averse to modding my headphones, especially when they are as cheap as these models.
