The HifiMAN portable player will be available on July 2009. * Estimated Retail price will be more than 700usd. We offer introducing price 600usd for preorder head-fiers. We will donate 10% of the sale price of each HiFiMAN HM-801 to support Head-Fi.org.
*Release date was delayed 4 to 5 weeks because we decide to support 24bit 96kHz FLAC when HM801 player is available.
We will post the real picture of HiFiMAN player final product soon.

How to use a HiFiMAN player?
Warranty policy: 30 days refund, 90 days free replacement and 1 year repair. Customers will be able to buy 2-year free repair warranty plan.
FAQ
1. Will payment have to be made now or upon shipping in June ?
If you pay now, you will get $100 discount. If you pay on June after the product is available, you won't get $600 discount price.
2. Why coaxial?
Coaxial input on HiFiMAN is designed for desktop Hi-Fi CD players. For portable use, all you need to do is to copy music files into a SD card, and insert into HiFiMAN player. I don't think optical output from a portable cd player or a regular mp3 player is good enough. In addition, optical input consume much more energy than coax.
3. Why battery life is only 6 to 8 hrs
Sound quality is always the most important issue we will consider. With so many luxury chips inside, working current of HiFiman is about 200 MA. We'v tried our best to find the best Lithium Polymer Battery for HiFiMAN, and this is the best we can do. 8 hours is enough to play all day, then charge in the night. If you need longer battery time, please buy a battery. Battery will be available on June.
4. Do we have to buy the amp module separately?
No. You will get an amp module with the player.
5. Does HiFiMAN support Gapless playback? Does HiFiMAN support ALAC?
Currently, no. We will try to support ALAC and gapless in the future via software upgrading anyway.
6. How will UI be like?
UI will be similar to an ancient ipod.
7. How much can I DIY with this ones?
I can not image how you will modify this little guy. The board is so small, and full of expensive SMD components. In addition, there is no DIP socket on the board, or anywhere in the player.
8. Please tell us headphone output impedance and its mW per channel.
Current headphone amplifier board design: 100mw - 16 ohm; 64mw - 32 ohm; 80mw - 150 ohm; 40mw - 300 ohm. It can easily boost HD580 and K240DF.
Modular Amplifier Bay called GanQi Bay. We will provide its spec detail to headphone amplifier builders.
9. Battery and module upgrade possibilities.
The battery we currently provided is almost the best Lithium battery we can find. Four sure we will provide new battery for upgrading when battery factories can provide higher capacity battery in the future.
10. Is the outer housing of the HiFiMan all Plastic, metal, or mixed metal/plastic?
It is a injection molded plastic sturcture with Aluminium panel cover on both side. Will provide larger pictures to show more detail.
11 Is opamp OPA627AU, OPA627BP or cheapy OPA627AP?
The opamp is OPA627AU. We don't want to use this most expensive chip and "electricity eater" at the very beginning. We made our decision after a test between 10 different opamps. OPA627 is the most appropriate opamp in this circuit.
12. About gapless playback: I have tested the time length between two wav tracks: track 5 and 6 of Pirates Of The Caribbean: The Curse Of The Black Pearl [SOUNDTRACK] .I tried to use a stop watch to record how long the time will be, but before I finish the first touch, the track has been changed from 5 to 6. The time is shorter than my reaction time, and the average reaction time of human being is about 0.2 second. Maybe this mp3 player does surpport gapless but nobody told me this.
