Just asking, how come HD 668B is the most well known model of superlux headphones, and also HD681. I seem to cant find much reviews about the HD330 but the HD381 has good reviews. Anyone got a link to the HD330 review?

Nice review by 1st, seems like i will be getting the HD381 which is bassy and also good with the vocals.

Just got my HD381F from trio, Sounded REALLY GREAT our of the box, exactly the same quality with my headset (Logitech G35) but in an IEM . Cant wait to get it burned it soon. Nice thank you note by trio too

Anyone knows a good (perharps portable) amp that pairs well with HD381F or perharps even the HD 668B?

First thing I noticed from 668B is the how amazing the soundstage is compared with my 381F (obviously) and my gaming headset G35. The bass is as deep and tight as I hoped for ( a bit of a basshead myself ). Now I am just waiting for this to burn in properly and maybe get a good amp, using iPod touch need to put three times the volume to get normal listening level,LOL.

Anyone can recommend a good portable amp to drive the 668B? I will be using it with my iPod Touch and my desktop. A DAC/amp combo would be good for both of my sources.
