The unit has some scratches on the top, but It's good cosmetically overall and 100% functional. The performance is perfect. The firmware has been updaded to 2.1. On this version, DAC3 HGC can integrate perfectly with HPA4 or LA4, and will not make any difference from the newest update version 2.2 except the power management.

I also have a HPA4 on sale. These will be the best synergy you can get. I will give some discount if you buy them together.

My asking price includes PayPal fee and shipping cost.
