They do ship directly from Japan to Indonesia, most likely those batteries are genuine products IMHO

And you could talk to George regarding those Delipow 3.2V LiFePO4 batteries from China since someone in Taiwan actually liked them better than NiMH ones such as Eneloop, I guess that's probably why Red Wine Audio would choose LiFePO4

Just be very, VERY careful with equal number of LiFePO4 batteries and dummies/fillers at all times.


Thank you For Your info

Is this better than SR71b.?
For me sr71b was always disappointing amp, never really find anything special about it.

I did a/b ing againgt fiio, sr71b not much different even with the balance.

So I gave up on the portable gears.

Hope this isn't disappointing after all. :wink:

Hi, this bakoon amp is great for bigger headphones and is really powerful. I had SR71b before and it is probably not driving audeze or hd800 phones to its true potential. I am totally enjoying the bakoon for my lcd-XC and TH900. It is really powerful to drive high impedence phones and provide very usable range on the volume dial. It is overkill for iems with its power, though still fine as long as you lower the lineout volume.

I am little confused.
Is bakoon made in Japan or Korea?

Wow you have Heavy weight headphones like T1 Han HE 6 , these Two need more current fit HE 6 and Power For T 1 , i Think
Bakoon portable amp is The right One For you

Until now Dont have portable amp that really can drive HE 6 to their potential SQ
Only Alo Rx 3 B , The result is Good , not very Good or excellent

No Wonder RS 71 B can not statisfiec Your taste :D

IMO

It's as rudi0504 said.
 
Bakoon Japan is the original company, where all the SATRI circuit voodoo is engineered by Akira Nagai and co. They make products almost exclusively for the Japanese market.
 
Bakoon Korea (or Bakoon International) has a deal to repackage certain models with their own case designs, sometimes adding their own bit of engineering (for example, the batteries in the HPA models) and sell them to the rest of the world.
 
Usually, at least for headphone amps, the HDA models are JDM while the HPA models are International. There are some dealers in Asia, Aus and NZ (afaik) that do import JDM Bakoons, though.

So in a nutshell, its better to buy the Japanese edition for SQ, right?

 
Not that straightforward, me thinks. Some users here have stated that, with the desktop amps, the Korean/International HPA-21 sounds smoother than the Japanese HDA5210 it was based on, possibly due to the inclusion of batteries and/or different power supply. Then again, there are some that have countered that by saying the JDM version sounds livelier. Depends on the listener and the kind of headphone you're pairing them with, I suppose. I've only tried the HPA-21, and it was very, very good with a Fostex TH900 and Audeze LCD-3.
 
With regards to this portable amp, there's no Korean/International version available currently, so it's not like we have a choice. No idea whether Bakoon Japan will sell this internatiolly or not, though I'm sure you can "grey import" it if you really want one.

For my personal preference with TH900, I like this one even more than HDA-5210

Out the box my long waited Bakoon Amp HDA 5520

Source : AK 240
Amp : Bakoon HDA 5520
Headphone : Fostex TH 900
Cable : IC crystal cable dream line

My out the box impression :
SQ :
overall excellent , it is at the level from Wagnus Epsilon S , the sound character are different from these two high end amps

I wonder how the Bakoon will be with IEMs once you place an attenuator in between!! Maybe it could really be equal to the Wagnus or maybe even better across the board!!
