@bagwell359 I personally really enjoy my He6 SE v2 for the $600 I paid for it, played on my Burson Soloist 3XP via the xlr headphone out. It truly shines compared to what was "good" on my A90. I can say that I would place it over my Sundara, HD650, and in many respects my Beyer T1 v2. But to be honest, I wouldn't say that it "outperforms" my HEDDPhone One... (It's just "different".) I feel that it performs in accordance with other ~$1.5-2K headphones I've heard or own. Waiting on speaker tap headphone cable to hook it up to my HK-870, so it MIGHT jump again in performance if rumors are to be believed, but I'll reserve judgement. Not knocking it. I like it A LOT. But so far I am feeling that I was already getting this level of performance with a headphone that didn't require modding, special amps, or gobs of power. So it comes down to what you want. I'm not disappointed at all with the He6 SE v2, but I could see how others might just as well spend the money on headphones that are "lower maintenance" and can be enjoyed "stock". I will continue to pursue as far as this pre-amp via Burson Soloist 3XP, (It requires special NA2F-D0B-TX XLR to RCA Transformer Balancing Adapters to go from the XLR outs to my HK-870's RCA inputs that arrive Friday.) into the HK-870, but I think after swapping pads, changing grills, and all these proprietary cable accommodations, I'll end upgrading it there.
