Holo Spring 3 R2R DAC Review - Punching Up!

The Holo Spring 3 is a truly fantastic DAC punching above its pricepoint, and with some unique features that make it an extremely compelling choice. I can comfortably say I've not heard a DAC this good anywhere close to this pricepoint.

This unit was loaned for review by Holo Audio.
The spring 2 was loaned to me by my friend Koji (ConvinceMeAudio)
