The HFM HE6SE v2 is a absolute joy, but only if you can power it correctly. I'll pull out my old dx3 pro plus tomorrow (if I have power since there's a snow storm in my area) and try my He6se v2 with them. I had a little bit of fun with EQ and my He6se v2 and man they take EQ super well. I was able to get chest thumping levels of bass but needed a ton of power to get them up there. My beta 22 amp does like 5w at 50 ohms and I was really pushing the volume to 2-3 o'clock with a -40 db preamp gain along with a +40 db bass shelf. Obviously I don't have those settings all the time I just wanted to see how much bass I can get it while still having super clean and detailed bass. Oh also be warned they are pretty heavy with the double sided magnets and all (I think almost 1 lb/450 ish grams)
