My HE6 SE v2 is here! TOTAL thanks and respect to HiFiMan Customer Service. The original ones shipped are still "lost" somewhere with the USPS, but HiFiMan next-day shipped me a replacement pair once the USPS presented their results from their "lost package" investigation. Hooked it up and immediately swapped the pads and settled on Dekoni Elite Fenestrated Sheepskins. I know that some people don't care for them, but I like them a lot. Played through my Denafrips Artemis, they sound "good", but not nearly enough "oomf" to get them to enjoyable volume. The technicalities and placement are awesome, but it's just not enough power... My Topping A90 is the exact opposite, enough volume, but it leaves me feeling like all the music is behind a plane dimensionally. Plenty of left-right, but the soundstage is VERY "2D". I guess this is what people refer to as "wall of sound"? So now I'm seeking a Flux Labs Volot (Back-ordered), or possibly willing to try the FA-10 as I'm hearing good things about the pairing, but don't want to always regret "not going the whole way". Not really too interested in a power amp tap setup if I can help it, but I'm not totally eliminating the possibility if the evidence is to the contrary vs any integrated offerings. But I have high hopes for the Volot. Completely by accident, I found the Ferrum Audio "OOR" amp that also seems to have potential... No reviews, so I'm seeing if I can arrange a demo. Anyway, I'm happy with the HE6 SE v2 for now, and look forward to releasing the other 30% potential that I'm guessing that these still have left to display! I consider them a compliment to my HEDDPhone and upgrade over my Beyerdynamic T1 v2 already for all things but soundstage placement (Again, that "wall of sound" issue with the A90, but even flat, the HE6 SE v2 sounds great, wider, and more detailed.)
