Just recently got into the head-fi gear and bought a HiFiMan HE-400 headphone to go with the HA-INFO DA1 DAC. Both units are being burned in and sounding nice. I'm interested in the tube sound and came across this thread. The HE-400 has low impedance so it's easy to drive with the DA1, but as dpmalito found out, the orthodynamic headphones are a bit heavy (the HE-500 is heavier than the HE-400) and I'm slowly getting used to the addition weight.
So my question is the pairing of the HE-400 with Aune T1? Also, how does the Aune T1 compare to the Tubemagic D1? Has anyone checked if plays bit perfect?
