I remember when I first tried the Campfire Andromeda (OG) years ago. I had long been into high end headphones, but was wading into better IEMs. I could've nitpicked, but they were so engaging overall. After a while, though, the fit for me just wasn't there and tonality wasn't what I was looking for long term. A gazillion attempts later at my brain wanting technicalities, but my heart wanting engagement, while my ears really didn't want hot spots after 12 minutes, I, a bit reluctantly, bought the Advar. Because I'd developed so much acuity on ranges, at first I felt like there was a bit of a gap in the upper mid to lower treble and then a tiny spike/splash in the treble. But then, something happened. Brain burn in, whatever. At any price range under $2k, the enjoyment to comfort factor has never been higher for me. It's just so dang fun and engaging. It has just enough dynamics / technicalities that I still appreciate acoustic and tight jazz. But its overall presentation is where this thing sings.
I do use the upgraded 4.4mm Meze cable, which is fantastic. I initially used the Questyle M15, which was first impression amazing. Then I plugged in desktop and it just opened up like crazy. So, I ended up with the Gryphon, because if you do A/B with the M15, you'll definitely notice a difference in soundstage. It truly makes the Advar sound more like headphones. In fact, I'd say they sound more like a better tuned LCD2 Closed (no wonky mids) when doing so. So, that's my $.02. I'm not dumb enough to say "end game", but this one will certainly "pause" my game longer than anything ever has due to sound and comfort, plain and simple.
