Happy new year :) I find the 7HZ 71 dongle DAC AK4377 quiet good, it has 70mv at 32ohms, cost less then half price then Sonata (178mv at 32 ohms) but has less then half output power. An alternative could be the Jcalli JM10 pro DAC CS43131 95mv at 32 ohms.- Lobarkaine

Hi AmericanSpirit, very interesting comparison,. I don't know if you have the IKKO OH1 but I'm wondering about the sound comparison with the HEXA.

To try to give you an idea I may tell you the volume needed to drive the E4000 with a MI9 Lite at a good sound impact. JM10 90,% 7hz 71 80% Avani 78% All this dongles have nice power, but I suspect they are not the top to drive demanding headphones with high impedance. Reading Andy's review...- Lobarkaine
