I am using my HiFiMan
with both MY UE-10's and my JH-13's and I am not experiencing any hiss on either can. There is a popping noise when first turning them on, but that sounds to me like a DAC pop.
I have stated this in my own thread, I know that Jude, Sasaki, and I were the lucky first three to receive these, and let it be know that they are not prototypes, just the first 3 that were released, and i an say unequivocally, that this unit is the best combo unit that have had the pleasure to grace my ears.
They have power, grace, and finesse, and are the sound that I am looking for without having to have a separate LOD, dac/amp combo, and DAP.
They are everything that they are advertised to be, plus more. My hats off to Fang for his vision, and insight and hard work towards making this come to fruition,
You couldn't deal with a better man/woman. He is the epitome of what an MOT should be, and I'm proud to know him and be an owner if his products.
