ya i think it's cos of onboard soundchip.

Thanks a lot for your effort.

Other than iamyuanwu, trio said that he found a supplier, but they're in the process of creating it IINM..

That's about RM60 per pair? Nice! But sadly there are only 2 in stock..

http://item.taobao.com/item.htm?id=8859938373 around 15-20 rm more but have 8

Oh! If trio is working on it, then you guys have little to worry about. I trust he'll bring them in for very good prices.

But regardless, I'll see what I get, if there's anything good I will update you all.

after i got my HD681, and an X-FI XtremeGamer to use it on my pc, i still feel the SQ lacks something, itching maybe for a headamp, but is it actually necessary?

try getting a dac out to amp den to phones. i don think the xfi sounds very nice. i'll look at audio gd nf 12

Doomsday, technically speaking it might be your laptop's that's causing the hissing. Due to the packed nature of the Laptop components simply getting electricity running through all of them might cause a hissing sound. Perhaps the lower frequency sounds masked the hissing?

Just throwing ideas out there. But I would suggest you to try other sources and get the conclusions yourself.

yeah too early to justify the hissing sound right now. Outstation currently, yet I didn't bring my Superlux with me
Thursday only can have my "music porn" LOL

Let me update a little after burning in for let say 10 hours for the HD668B.
It's getting more natural to listen to it, and listening to any other headphone become unnatural to listen it to.
Now using PCM2704 -> cMoyBB 2.03 (OPA2227, still the best for bass)-> HD668B. All with my diy cable.

When listening to rock pop, you can hear full bass, rich treble many many sound yet you wont think it's noisy at all as all instruments is clear and very musical.
Another way to tell how good this headphone is, when you put it on, it's very hard to take it off as all music you listening is so amazing and addictive.

Please I beg all entry level headphile/audiophile people to get this cans first before paying hundreds and hundreds on other cans.

Awww tempting 668b... From all the reviews i read so far... 668b is the best bang for buck right... Other cans have got impedance too high for direct output from my mp3 player/laptop. 50+- Ohm should be nice for my laptop. I think that's also the max my laptop can go without an amp... Others with 150 ohms can't be considered at all... Sweat!

50ohm is quite easy to drive. my iems are 50ohm but i feel tat on the fuze a little more juice would be better. just feels a little lack in power

I don't think my phone (Nokia N82) can drive 50 ohm well. When i'm on it with 32ohm can, at 100% volume, barely satisfied me. But my laptop, a dell studio series should be able to drive it loud.

For the Taobao ones. You guys know anyone that can help us do order from China? I know most Taobao sellers don't send overseas, and don't accept overseas payments.
I have a few friends in China who may be able to help. But courier/EMS to Msia... tak tau berapa; and how to pay him... I also tak tau.

Enigmatic,
I'm a bit OCD. So I'm currently only interested in AKG's velour pad. Lain-lain tak mau. Hahahahah!
If you can get cheaper and faster, I'm all for it.

got pple on hardwarezone doing spree for taobao
1 pair come in at $35.62 sgd. maybe check if got pple doing orders from them in lowyat or other msia forums?

Lowyat got ppl doing bulk order for taobao like the one below http://forum.lowyat.net/topic/1703079/+280&#entry41620754

opa is famous of giving in warm sound signature into any headphone that was attached to it.i think I get the idea on how it sounds now.

Stay away from using LM series opamps for the headphone through it will sound veiled on mids which is bad really.

A bit out of topic, but for those having diy headamp and wanna pair with HD668B, I would recommend opa2227( laid back, warm, bassy) and AD823 (delicate mid, nice soundstage but not as wide as opa2227) .
I have LM4562 as well, but I quite don like it with HD668B cause it makes the soundstage narrower and too analytical.

Using LME49720 here,the result is the same on what you described on LM4562 currently

hello ebelibodi..which one of superflux is great ? Im new with superflux model..izzit true perfom same as MS1

I don't think they perform the same really.While HD668B is more towards into clarity the MS1 is more on musicality (a term that when you listening to a song you'll be enjoying it instead of noticing some simbilances that the song has most of the time) instead.Other then that MS1 isn't that picky with amps and sources compared to HD668B which is when you applying it with a wrong setup it would sound probably as good as any under RM100 headphones on the market.
