Holo Audio – Cyan 2 DAC (US)

Fantastic R2R DAC! I’m using the Cyan 2 in a dedicated headphone setup, and its compact size fits perfectly on my nightstand. The sound is wonderful—textured, detailed, and spacious, with a natural presentation that makes it easy to get lost in the music. Paired with my Bottlehead Crack OTL headphone amp and Sennheiser HD650s, it’s been an absolute pleasure to listen to. Couldn’t be happier!

It sounds like "nothing." But it's the best sounding "nothing" I've ever heard :^)
