GoldenSound wasn't a big fan of Immanis (Though he did say they are good, just not for the price) and he's a fan of Susvara's. Vitaliy from Flux Lab Acoustics also didn't seem to be super hyped (Said they are interesting headphones but that's about it) about it, and he likes X9000 better than Susvara
Will definitely write a few words about it, I'll be there for a whole day 10am to 8pm, maybe a bit less most likely, but definitely for more than half an hour
My experience with Susvara is from an inferior setup, though a tube amp, I think Cayin HA3 with iFi DAC, I didn't feel that it was lacking, from the same setup both headphones side by side (Caldera) were different in presentation but similar in performance, maybe Susvara was a bit ahead, it had a bit of a more articulate/ethereal sound, while Caldera was cleaner and more natural. From my current setup it's obviously better than Susvara on that other setup with really great stage and imaging (On better recordings) and great texture and bass that feels like it is actually produced by the instruments playing instead of the tube bloom that was from that other setup.
