David –
I can really hear the difference between my old psu and this one. So detailed and deeper sound.
Florian –
Perfect for powering my Orchard PecanPi DAC card. Detailed, dense and musical sound. I added a SR Blue fuse with excellent results.
Sebastian –
I am so happy with this PSU, it perfomrs really well with my Katana, warmer and more detailed sound. Thank you for this awesome prodcut!
Dean Haas –
Bought two of those 6 months ago and so far zero problems, couldn’t be happier. Smooth and warmer sound. Totally recommended for custom builds.
Josh Parker –
Outstanding quality and performance, so far working as expected. Would be great to have a case to house it, hope that it will be available soon.
