hmm.. quite possible actually..
cmoy is around RM190
superlux 681 is RM89 .. for anti-superluxors, get a KSC75(not recabled)
and cable if you DIY yourself should cost you RM15 (canare 1m + neutrik)

id say why not XD

grados and superlux are playing in different games lol so i wouldnt say its a competition; but nonetheless they're both good pairs of cans.

price wise, the superlux is no doubt tempting... to a point that you wouldnt really hesitate to grab one if its ready on shelf.

a good poison i'd say. the superlux is, however will require some decent juice to bring out the potential. i wouldnt really recommend if youre just gonna plug in onto an ipod or iphone and go around.. it will sound like it has not enough body and might be a little too bright to some. same goes to most laptop onboard sound.

havent tried that USB DAC.. but its decent enough on an X-fi tho most of the testing ive done are on my friend's maverick D1
the 681 however performs well on a nokia xpressmusic phone
