This is on their Hibino/Japan website.  It seems like exactly what I'm looking for, using an AKM DAC (I'm just not a fan of the handful of Wolfson devices I've used)  I did a search for D55 on here, and turned up nothing surprisingly.  Looks like you can get them on Amazon also, and its listed as a Japan Import.
 
Any thoughts?

the most interesting is it uses xmos chip for USB which I haven't seen of on a portable dac. XMOS is a really good low jitter usb chip. Biggest issue with most portable dac is they use quite poor usb implementation like PCM270X series. doesn't matter what DAC chip you use poor usb implementation will always makes the sound less than optimal

 

[revolutionz]

Yes, I have heard of the XMOS chip, but have never experienced one.  My DACmini is supposed to be very good with jitter, and that also has an AKM DAC, so I'm quite hopeful for this one.  I think I am going to order it, just not a lot of specs on the power delivery, hope it will power my HD700's just as well as my IEM's

how does this unit sound compared to R10 and DX100?

 

[palermo]

Is that the same DAC chip to fostex hp-p1 used? Interesting indeed, since I've never know iBasso use AKM chip on their line prodct before. I am not a fan of iBasso, but this one get my attension. Hehe
*iBasso use XMOS on D7

Bump

Has anyone heard how this device sound yet??
Now it's price dropped to 280 dollars.
I'm interested in this unit but it's hard to find a single review that is written in English!

I ended up giving up on it.  I bought a Centrance Hifi-M8 for my desk instead.  I knew I'd like the sound being I own a DACMini, and it is a perfect setup for my desk.  The iBasso unit looks promising, but I just didn't feel like being the guinea pig on this.

it's hard to decide. It's weird to not be able to find a single review. It came out 1 year ago.
No one has written a review yet. This unit has everything I need. I just wonder how it sounds...

 

[revolutionz]

I originally came across it because it used a similar DAC chip to my DACmini, which I liked.  I'm a big fan of Sabre DAC's but you don't find many smaller/portable's that use them.  So, in my search for a small DAC/Amp for my desk at work I found this.  I still wouldn't mind giving it a go, but I need to sell some of my extra gear first, I've started collecting too much as is all to common 'round here.

People on iBasso D42 thread are praising D42's sound quality. However, D42 supports max 16/48. It can't decode HDtracks albums or vinyl rips.
I have used DX100 / R10. Their sound quality is the best I'be heard. I'm guessing D55 is nearly as good as the other iBasso devices but no one has confirmed this yet.

Please write a comparison review when you buy this!
It sells for 260 now.

I bought this unit. I will let you guys know what I think.
I'm going to use it with my HTC phone and Nexus 7.

I love this tiny device guys!!! It truly has 20 hours of battery life. It sounds much better than R10 / DX100!
It sounds 1.8 times more detailed and spacious. This product is clearly an upgrade from R10. It works well with my Nexus tablet and desktop. I'm totally impressed. It has a big sound stage, clarity, long battery life, durability, small size, etc. I prefer this over R10, Sony PHA2, HM901, and Geek Out 1000!
