OK, 'got my upgrade back for the V2 and bottom line could not stop listening. It's very compelling and engaging, more engaging than the V1 which seemed more point-source oriented than the V2.
The sound is much for distinct and well defined, the bass is deeper and clearer, and the mids are nice and silky, and the highs are sweeter than before.
The resolution is also very good. Not quite quite as good as my Stax SR007, but up there.
It's a very good balance in the tonality, not veiled, not shrill, not metallic, not hard, but still smooth and liquid and good detail and speed, second only to Stax here.
(I'm a huge fan of the Stax SR007 mk2.5 if that gives anyone a feel for my tastes. I cannot deal with tinny highs, shrieking upper mids or vocals, or muddy foggy or overwhelming bass).
I did however get an improvement in the mids and bass (faster and more transparent) when I switched to my Moon Silver Dragon cable. The Moon cable does have slightly (emphasize slightly) brighter highs, but that
goes well with my system here.
System: Windows PC-->Chord Hugo TT-->Rudistor RP010B amp.
Just a great headphone with certainly no obvious flaws.
