UnfetteredWandering
Head-Fier
My HEKse arrived last Friday and I've been listening to it consistently every since, mainly from my Gungnir Multibit and Mjolnir 1 via the balanced cable. Like others have said before, they are very detailed and have a very enjoyable soundstage. One thing that should be mentioned, is that the brand new pads squeak a little against the ear pieces of my glasses.
I had the chance to try it with an LTA MZ3 and iBasso DX320 this past weekend as well, but for now, I think I will seek out a better cable (probably from Arctic Cables) in terms of usability (I'm currently using the Hart cables from my Sundara, but the splitter is a bit too low and catches on the edge of my desk. The included Hifiman cables are sheathed in black fabric).
