It sounds like you should just go for the EL8. Why look elsewhere if you really liked it? I'm not of the opinion that we need to sway you away from purchasing something you've tested out and thought highly enough to strongly consider purchasing. In other words, go for the easy win, man. Just get the EL8...
All we can do is tell you how much we love the AQ headphones. I mean out of the many headphones I tested at RMAF, there was only one pair that I liked better and it was the HiFiMan Edition X v2 at roughly three times the price I paid for my Nighthawks. I reviewed the original HEX and loved those, too. So I know that love is real, but there's no way I'd get three times the enjoyment from then vs NH, lol.
However, and this is a big however, that's just my opinion. It certainly doesn't mean HEX or NH or NO is better for anyone else. I'm not that egotistical, lol
