Burned mine in a lot with my Luminist enhancer disc. Have them hooked up to a Qables Iqube V5 straight to its DAC via cd transport and I have to say... it's a real shame that these headphones are not that well known. The mids and bass, soundstage, and separation to me are the standouts of this headphone with a nice somewhat honest top end, which should change for the better when I get a proper 75 ohm digital cable. Smiling a lot more lately. I think some people think I have another lady on the side. Nope, just my new headphones!
