Thanks Anakchan for a nice review.
I'll get mine in August, but this writing makes 2 months waiting time feels like forever... hehe..
Btw, just wondering what is that cable connecting your AK and the amp?

That was some cheap mini-mini cable I could find that was "long" enough. In fact it still wasn't long enough!

It's a bit ridiculous carrying around an amp weighing 1 kg, but hey if it doesn't bother you...
How is it with sensitive in-ears / customs?

I am going to be in Japan (Tokyo, Takayama and Osaka) in a few weeks. Can you recommend a shop to purchase one of these - preferebly Tokyo - I am loving the image of the Amp in the case with the A&K and Fostex headphones! This is exactly the setup I am looking for.
