Which piece of audio equipment did you upgrade from? Fiio K13 R2R
How does your Burson compare with it (sound, soundstage, detail, power)? Berson Voyager Conductor is much detailed, with a wider soundstage and more detail
What headphones or speakers, source and DAC are you pairing it with? HE1000 Unveiled, HD660S2, Accoustics 3050I
What function or feature would you like to see in your next Burson device? Less noise, clicking between tracks. Most likely clicking due to recalibration lock from a change in kHz.
