A moderate priced dac

Schitt Audio go there look at the DAC’s they have and pic a Multibit DAC and enjoy.
I have a Grungnir mb and am very impressed. I say Multi bit as its really quite organic sounding IMO compared to the delta sigma DAC’s.

Bifrost is right in the middle of your price range. I’m very impressed so far with Schiit products and customer service. I believe its a better DAC then an older DAC that’s was much more money when new, IMO. not to mention older DAC's may not have the connections you need let alone a good usb input for upgradability and interfacing with other digital equipment.
