Hello SBAF. Long time lurker to this forum - longer time headphone geek. I've always been obsessed with headphones, and it was quite a revelation in the early days of the internet that there were others out there who were similarly or even more obsessed. As a kid I found "audiophiles" (a rare enough group anyways) would look down on headphones (probably with good justification, especially historically), but since all I owned that sounded good were headphones, I thought I was just unique in that aspect. I've probably listened to just about everything out there (huuuuuge fan of the HE90s, even after hearing the SR-009s, etc.) but I make do with modded HD800s - probably helps that I'm over 40 now, so my HF hearing is probably not as sharp as back in the days when I thought everything sounded too bright on the average recording). Between the mod and a little eq (if needed) I find them pretty good, and even a decent value used, now that people are slinging $4k TOTLs cans left and right. I'm still looking to make the plunge into the world of electrostats, just bummed that I can't buy the HE90s and end my search for better headphones permanently. I do like Stax quite a bit, the 007s mkI being a particular favorite, it's just hard to find / take the plunge on the BHSE that they surely deserve.It will happen some day I'm sure, unless Sennheiser takes a 2nd shot at a HE-90 re-issue, the skipping of which I will always regret. In the short term, I'm looking for a better DAC that the PWD and DAC2 that I tolerate but don't love. Yggdrasil is leading the list right now. I'm an engineer by profession, so I like seeing measurements and getting that little thrill when you predict the sound of headphones (or any gear, really) before you've heard them - and the shock when the reality of their sound differs from predictions. But first and foremost, I'm in it to enjoy the music.
