hi Agent5. it's been almost a year now since i've been using this HD668B, and im still in love wit it. i tot in the 1st place it will be out of my favour but i was wrong. still satisfies me~

custom cable - new set of cable, custom or DIY to replace the original cable. if you can browse thru the audiophile section there were many forumers providing the service. these cables can be adjusted according to your budget and needs. the forumers can advice you to on the suitability~

for my usage, the combo that i use is PC -> USB -> DAC -> custom cable -> HD668B.

*if there is a year end bonuses for me, i want to buy a better DAC for my HD668B

Hello guitar89,

Im happy u bought the HD668B as well since its very good! i have been using it for some time now and its getting better the more u use it. My out of the box impression exceed my expectation since i use this headphone with the custom cable and DAC. (much2 better than my previous Philips headphone)

Right now im trying my friend's HD669. A forumer also and bought from Trio as well. He asked me to try it. Well, using the stock cable it got some noise but after i put the custom cable, it produce superb clarity and the noise were gone. But still need some burning tho, should give some time for its potential to explode~now he is looking for portable amp as well.

I haven't replace the short cable yet but i might replace it in the future. Will definitely post it here once i did~

ENJOY ur HD668B~!

finally i got my headphone amp to complete the package~! so happy now
