I'm enjoying hearing them! I've enjoyed even the waiting (not long - very good service by HeadAmp!). The packaging would have been appropriate for an original Picasso, or the Mona Lisa, the 8 Philips Head screws, and multiple taped layers - the precisely calibrated Russian doll of boxes.
But....DAMN!!!! is this a pair of cans! I need more listening time. I use Ralph Towner Blue Sun, Dexter Gordon, Go; Latest remaster, 192/24 of Steely Dan Aja; Joni Mitchell Overture/Cotton Avenue, Genesis Seconds Out - The Cinema Show, Richard Thompson, Amnesia; a HiDefTape Transfer of Heifetz playing the Sibelius concerto on Mercury; Some Schubert strings (Jasper/Kernis Project, the Fitzwilliam on Linn; and some Linn and 2L orchestral recordings. More on that later.
I can't say whether they're neutral - there's a golden hue to the music, if anyone can vibe with the synesthesia. But there is so damned much going on here! They're appallingly detailed. The Valkyria are both pleasant and bracing to listen to - as most music ought to be. Texture, weight, and Susvara-level resolution, at least. They are a distinct yang to the Suva's cool yin. If you are a little synesthetic, you might notice the sound billowing, with more saturated hues, iridescent and visually a bit deeper, coming out and meeting your skull, where the Susvara has all in proportion and meets you halfway, all glimmers and hues laid bare but with the right degree of illumination - a very subtle kind of flattery. The Valkyria loves to sing for you. This is pure impressionism, but I know my impression-language.
For a heavy dynamic driver headphone, they eclipse the Utopia in either version in every aspects of details retrieval; they remove the upper bass bloat and weight, and have no particular brashness in the highs, which nare both realistic, assertive, and vanishingly deli9cate, as needed. a full, tactile, textured, and yet high articulate, dynamically fine-grained bass; first-class impact; the best holography I've heard, utterly without etching, with both small and vast distances, layout, differences between the ambience of one musician and another separated in the recording - although the Final D8000 Pro, the Abyss 1266 TC Phi, and the Susvara aren't deficient in this department, to say the least. So far, this feels like a greatest hits of each headphone. With he heart of an engineer who used to have it bad for Grado.
So, first impressions, apart from the barest timbral euphony, which might be me, feeling privileged to be wearing these things, these are both as fine grained and gifted with micro and macrodynamic variety as I've heard (I live with the aforementioned, plus a nice collection of beloved Grados). my ears and body and mind are pleased. Music feels good, and there's SO MUCH OF IT! There's a lot more to listen to. And there's getting used to the status of the item - no biases allowed.
BTW - I haven't played with new pads or cushions not he GS3000. I never felt the urge. I did, however, place a bunch of Dekoni nuggets, or what are they called, on the underside (obviously) of a PS2000X headband. Yes, more comfortable, and stays put a bit better. And, yes, I wrote PS2000X....X-driver tech installed in the PS20000e uniform. Still love my Grados. They have always done good things in a way unique to them. Maybe someone would like me to call the Valyria a cost-no-object fever-dream fulfillment of the Grado aesthetic or musical universe, or whatever. I won't say that. But I will ponder whether it ends up being true, or helpful to say. I mean, there's a kernel of good old Grado chutzpah here.... but let me not mislead.
