So which DACs synergize well with the 339 now a days? When I was originally looking into the 339 and did a bunch or reading and research, it was the HRT Music Streamer II and II+. I see the HRTs are no longer readily available new and wonder if there is something better. I'm thinking of upgrading from my Maverick Audio TubeMagic D2 DAC and so I'm starting to look around. Bifrost Multibit? Audio-GD? I am also considering getting a DAC that has Balanced Outputs, so I can try that out later down the road. Any recommendations to consider?
