Pono Player with HD800 balanced cables. Cardas cable and connectors assembled by HiPhibian, excellent quality. Volume increased considerably, probably 2-3 times. It gets uncomfortable when turning the volume to max. It is very difficult to compare it to the normal unbalanced mode since the volume is so much higher. If I had to comment - I'd say that the bass and mids area bit more pronounced. Sound stage is wider. However, these probably are all a result of the volume increase. The music quality is faultless. It makes me wonder why I spent so much money on other equipment. I'll compare it to the Jotunheim + Jotty internal DAC or Vivere DAC combo when the Jotty arrives and send an update. Does anybody else have experience with Pono in balanced mode, what is your opinion?
