Mark’s Burson Funk with Audioengine HDP6 and Audio-Technica ATH-M50x

Published on

Post Info

Excellent amp. Voices are very clear and natural whether singing or speaking. The amp is very well balanced between the bass, midrange, and treble. Because of the low noise floor it’s easy to listen at higher volumes, However, listening at quiet levels still reveals tons of detail. I mostly listen through speakers, but the headphone amp is excellent too.
