And the Hugo 2 can only be better.
Primarily based on your review, comments from Jude, and other forum posts, I added the HE1000 V2 to my Amazon wish list as my open-back planar magentic option. After researching it seems there is no better planar magentic option. Reports say they are lighter and more comfortable than any flagship Audeze, are more resolving for less, and even seem to beat out MrSpeakers Ether Flow for detail and on overall sound signature uniqueness. But as you say the HE1000 V2 is not as well rounded as the Ether Flow on build quality, maybe pure neutrality, and being easy to drive. And the HE1000 V2 takes a mighty amp to get there. But I wager the Pass Labs HPA-1 I plan on buying can tackle them nicely. However, I probably will not be able to use them with the WM1A Walkman.
Now I just need a portable closed-back headphone and my proposed headphone wish list is complete. I hope the new MrSpeakers headphones you mentioned come through. I can't wait for your review.
When I get all this gear, which admittingly will take a bit of time, I also want to do some YouTube videos on them. You are my gold standard reference on YouTube headphone reviews along with Tylar from Inner Fidelity and Jude from Head-Fi. Although initially I'll be at a disadvantage as I'm research heavy and somewhat lacking in extensive demo / comparison experience.
