Marantz HD-DAC1 – Reference Quality Headphone Amplifier, Digital-Analog-Converter & Stereo Preamp All-in-One | High Resolution Audio Playback | iPod/iPhone Compatible | MusicLink Space Saver Design?

Marantz DAC1. Had them for almost 2 years and love ‘em. They drive my HD800 as well as AKG K702 & Q701 beautifully, great definition, power to spare and tons of flexibility & inputs. A steal at $799!

This is the dac/amp I’ve been using with my 800s for over a year and it’s a magnificent match : https://www.amazon.com/Marantz-HD-DAC1High-Definition-Headphone/dp/B00NTR459S/ref=mp_s_a_1_3?keywords=marantz+dac1&qid=1563063742&s=gateway&sprefix=marantz+da&sr=8-3
