I purchased this with reservation and got it when it was released.
Specification of this headphone amp is so powerful and I have no way to utilize full functionally active at this moment.
I use this one simply as a DAC for iPhone and macbook pro with micro iUSB and iTUBE.
I also use AirPlay with Airport via toslink cable since it's too easy for streaming music data with iPhone and macbook pro.
It comes with lots of cables and attachments.
and manual is so simple and this isn't enough for advanced users, so I refer the following page (in Japanese).
This is the decent review of this meaty monster, but written in Japanese, so you can use google translate to the language you'd like to read.
