You'd probably like the Stellia. I loved the Clear MG I tried but ultimately I passed on it because I have the Focal house sound in my collection. So you'd be presented with the same thing I'd imagine. Double down on that sound signature? Or try something else?Agreed that there is no perfect headphone, better luck catching a dragon .
I have not heard the stellia or the th900mk2. I've always wanted to try both of them but never got the opportunity and didn't want to buy blind.
I have the Focal Clears and upgraded the driver wires to 18awg mundorf silver gold and resoldered everything with mundorf supreme as well as change the pads to custom leather pads. They have excellent bass impact but doesn't extend well, tapers off in the sub bass region. As much as I enjoy them, I need closed backs due to others in the household.
I found the aryas had great quality to the bass but lacking in the impact and volume to satisfy the itch for me.
I recently purchased the TRN Kirin which is a planar iem and it has reinvigorated my interest in planars, the speed is quite addictive and while the clears are quite fast for a dynamic, I find that it still can't match the speed of the planar.
This is why I'm very interested in the Sundara closed back.
I think ZMF may reach deeper. Definitely try the Stellia and some ZMF if you can. If you're after the speed, the Stellia may be fast enough for you. I was a huge planar fan, but the dynamic drivers are getting so good now that I think they're just barely losing out here in terms of speed with some of the newer stuff that's coming out.
