hi guyss. *hormat*

newbie 2 days HD669 user here..
i paired my can with my xfi titatium pci-e, n tune according my taste.. just burn it around 15hour..

do i still need DAC n Amp to maximize the can output? currrently eyeing on Fiio E7 but the main question is, will be any huge different music that i hear? if using onboard sound card, mybe i can tell, but i'm using the xfi titatium now..

beside E7, any others can u recommend?

what about T-muso new mini USB DAC card (quite popular i think here) + (insert ur recomend portable amp around 100-200)

i think after several days using the HD669, the bass getting better.. currently listening to Eminem - Lose Yourself.flac. sound quite good now..
