Pros: Nice construction, amazing sound, great value pricepoint
Cons: honestly I find none yet, I do not use usb but there is no usb
This exceeded my already high expectations. I ran this from my macbook with the optical cable, used my Matrix M Stage and Yulong A18, even my Ibasso D12 as my amp choices.
I use HD 650 and 598's with this unit.
Not much of a review but if you have questions I will gladly answer as best I can.
