HM-602 Portable Music Preorder

post #1 of 640
Thread Starter 
We have shipped most preorder batch HM-602. HM-602 Preorder will be finished on Monday, Nov 1st. From now on, we will not provide free RE262 IEM with HM602.

It is well known that Non-oversampling dacs offer great sound for little money. HM-602 is the first portable player using non-oversampling DAC: Philips TDA-1543. As younger brother of HM-801,  HM-602 shares HM-801's great sound signature. To make it as portable as possible, HM-602 does not have amplifier modular design. However, its headphone amp part is very similar to HM-801's standard module. To drive both high impedance and low impedance headphones, HM-602 with the high / low Gain switch can drive both high efficiency IEM and most full size headphones.  In addition, HM-602 also can work as a USB DAC.

 

Firmware and music format support: Same to HM-801

Note: TDA1543 DAC chips are tested used chips because TDA1543 was discountinued many years ago so that it is almost impossible to find new chips. We promise that all chips were tested. We promise that we will run-in HM-602 players for more than 24 hours before ship them out.

Impressive. Although I have a few questions. Gappless playback? Expansion Slot? Weight?

Gapless playback is not supported, but the gap between tracks are very small.

Fang,


Can you post a list of tested and approved SDHC card models (make, storage capacity, classification) that your engineering team recommends for both the HM-602 and HM-801?

 

Also, what will be included in the retail package?  Leather case option or pouch?

 

Thanks!

I saw on hifiman website that the preorder price for hm-602 is RMB2399. http://cn.hifiman.us/products/?pid=90. Can I preorder on that website and pay by paypal? Also can I get hm-801 charger from that website as well since it is RMB149 compared to USD49 on head-direct website. Thanks.

Can you also post a picture of the charger too. Is it the same big charger that came with the hm-801? Also the battery of hm-602 cant be externally change. So what happens if after 1 year the battery starts to degrade. Will we be able to send it back for a battery replacement?

Is the charger EU compatible?

Is there a way to lock volume?

How long will it be available at preorder price?

 

Thanks

Hi Fang, I see it uses the 32 Gb SD cards. Will the software be tweaked to allow larger cards in the future? Also is the battery user replaceable? A case would be a nice addition. Thanks.

Anything >32gb is SDXC, not SDHC.  Different hardware, not software upgradeable.

Check out the last pic in the first post.  It's a single port, so it will be a lot smaller and lighter.  I'm guessing a cheaper universal switching power supply.

That alone is worth this price.  I did not realize it.  Awesome!
