Sorry to resurrect this thread, but I have a Origen+ and have been very happy with it, although I also had problems with the USB connection/drivers and ended up using the optical connection.
Unfortunately the Origen is out of warranty and the headphone input is failing; I'm thinking of replacing it with a Topping D30, and maybe the A30 amp or a Magni 3.
I know the D30 has received much praise on this site, especially considering its price point, but does anyone have any info or thoughts on how the two units compare sound-wise?
Thanks!
