Hi Lu, just sent you payment for a stereo and a balanced kit. Thanks for making these available.

Do you have any information on the headphone amp from your website? Is that available as a kit?

Many thanks twitchie 🙂

Do you mean HAK_ONE or Ortho No.1 ?

I post the PCB of HAK_ONE and the Test result of Ortho No.1 on my blog.

For HAK_ONE, I got many postive feedback from my friends, they say it is the best Headphone AMP for Audio-Thchnica ^_^

But I want to make the Ortho No.1 out frist, because to my listening, it is the best Headphone Amplifier for my HD650. Especially the BASS

May be 60 days later, the Kits of HAK_ONE will be available

I want sell make my Headphone Amplifier as a completed assembled product, not kits 🙂



the bandwidth of Ortho No.1 is wider than 0Hz to 2MHz 😀
the picture shows the 2Hz square wave response:
