Huge thanks to Kennerton and @sorrodje for the loaner, I enjoyed my time with these. My impressions are mostly consistent with the majority so far so I won't labour the point too much. In a nutshell... + An actual decent sounding headphone without major FR issues that doesn't cost stupid money*. + Fairly sensible tuning, bit of a mid-bass bump for fun but not too much. Eg, bass that sounded muddy on the Z1R (Fiona Apple - "To Your Love") was tight on the Vali. + Punchy, good slam (not playnar levels, but not a million miles away) + Solid build quality. I was expecting an ergonomic fail from previous reports, but I found the adjustment to be fine, set & forget. + Wears its (admittedly considerable) weight quite well on the head. + Sensitive, easy to drive - * still too expensive though. - Not super comfortable with eyeglasses. I think it's the weight pushing down on the sides of the arms. - Narrow soundstage - Not anywhere near top tier in terms of resolving abilities. Subtle details are lost compared to HD800 and (to a lesser extent) HD650. - Not entirely natural sounding, but for me I think this ties in with the lack of resolving ability. - Sensitive, well into the noise floor of my Wells Audio amp (which admittedly has far too much gain). Honestly, I'd take these over an Elear just for the lack of glaring FR issues. I think most headphones at this price are too expensive though. Vali would be an easy recommendation at say £500-£600 retail. Taking into account the used market though, I'd still have a used HD800 and mod/EQ it for a similar price. Good job Kennerton, and kudos for letting us all have a try.
