Audeze cans love a direct connect, and few connect more (with their current drive and single stage circuit) than Bakoon's HPA-21
This combo will set your hips to sway and your feet to move. There won't be any stopping them. Add to that a dac with a similar gestalt of directness by Metrum, and the party's started. The Pavane DAC is just that. Why, you ask, would we pair the top reference dac from Metrum with this combo...because it's a perfect aural match, that's why.
