EF600 (open-box)

After the first listen, I waited about twenty hours for them to break in before reviewing. My setup: Rose RS520 with AudioQuest Cinnamon USB cable sends the Hires files to the EF600 to drive the Aryas. The sound is detailed but always velvety, never harsh, airy, powerful but not intrusive, and full. Now I understand the reviews that define this sound as material, I think that's the correct term because the sound is very realistic, palpable, across the entire range, a real delight for the ears. Finally, the power is exaggerated with the Aryas; I don't think you can humanly go past 9 o'clock with the volume knob. I'm truly satisfied!!!!!

Golden. Makes my Arya Unveiled shine.
Truly the monolith from 2001: A Space Odyssey. :D
