To build the fantastic Pass DIY HPA.
I ordered a small batch end December for my best friend and have some boards left to realize a minimum order quantity of 5 boards.

-HPA Board (2 avaible) 25€ each
-Universal PSU (5 available) 35€ each
Worldwide shipping by registered mai.

Both boards are high quality boards with soldermask, silkscreen, 2oz Copper.

The Universal PSU is compatible to the HPA and also a good PSU for a DAC or a Preamp.
See attachments. One picture shows a example build.

The Pass DIY HPA is a diy audio project authored by Wayne Colburn and is for the diy community.
The HPA-1 is an official commercial product by Pass Labs and has nothing in common with the diy headphone amplifier, the topology and design are completely different.
That being said the diy headphone amplifier is an excellent design in my humble opinion.
