To make the DT-Reference it takes more than the spirit to pursue perfection. It's the persistence to produce only the most enjoyable yet authentic sounds on a headphone level, an endless pursuit of "there must be something we can do better".
And never before will you hear such loyal sound being produced through your high-end headphones driven with this remarkably exquisite and artful tube amplifier. That will be very unique to only you and be set for life.
