I gave it to a friend. One of the drivers buzzes with certain bass, usually orchestral, she hasn't heard it buzz yet so Idk, but yeah, idk how to fix it. Anyway, it doesnt buzz often and I do know how it sounds. Arya has an effortless quality to it. The image is huge, the detail is easily pinpointed, it's just laying out for you in a nice display, timbre seems right. RP18 has a lot of these qualities, just not as much. Not as detailed even though they are detail monsters in their own right. Bass isn't as impactful. Treble not as sparkly maybe, although I used a certain kind of foam to damp the drivers which I felt boosted treble a smidge to a nice level. Um, their stereo image is I'd say just right, as in size. Like it's a homey size, it's not gargantuan like Arya's, but I'll be honest, I rarely listen to Arya's, it's like a rare treat its characteristics, I'm mostly knocking around with vintage planars these days which are "enough" for me to have fun, and even 40mm YHD's can be fun for the tiny little image. Dude. I was listening to HP-50A's today and decided to measure them. Check it out.
I actually think I prefer these to YHD's.. Makes me want to build a YH-2, I think I would prefer that to YHD as well, these were tuned weird, I think the bass should be better even though that's velour earpads, somethings wrong, imho. Has anyone gotten HP-50A's to go flat to 10Hz?
Anyway, when I had YH-100's and RP18's side by side RP18's hands down. More detailed, although this was before I gave YH-100's paxmate treatment. I think I prefer the soundstage with RP18's in the Beyer clone enclosure... Just really pleasant. I was thinking they'd be perfect portable cans if they weren't so huge. Kind of amazing for bedtime with my portable setup. You saying YHD's are AS DETAILED as T30 doesn't sound right to me at all, I've never heard a T30, but just looking at that driver and stuff, Idk... RP18's were next level, imo, beyond YH series and YH series beats out YHD imho.
