It has a natural signature, it is powerful, authoritative, vivid and crazy clean. It does not color the signature of your DAC at all.

Instrument reproduction and notes feel lifelike and very detailed. The low region is punchy, fast, accurate and well-rounded. Just like it should be. Midrange is sweet, no overly saturated tone or problematic note thickness, it is as natural as it can be. Treble is airy, clear and very detailed. Extension is very impressive. No high gain degradation or signature change.
