This is a first "reaction," because the very first lesson I am learning about this V3 is how much it requires "burn-in." Out of the box, it sounded like a mixed bag of constipated, overly claustrophobic, and somewhat congested, not to mention rather thin notes, particularly at the top end... On the other hand, I could hear some hints of something "larger" and more spacious behind that mess==e.g. some larger than usual bass notes, knocking the door just behind the "mess," and certain cues "behind" the frontal presentation that seemed to suggest that V3 had something quite special and rather spacious to show me... Keep in mind, that after owning several Hifiman cans, I have learnt how *not* to allow any such first fresh-out-of-box salvos of "sub=par" presentations faze me...
To return to the events of this evening, I have since replaced the initial cable I was using (not stock, which I've never bothered to unbox as yet) with a bigger gauge one a Norne audio Silvergarde S4 8-wire, and after about 6 hours, my head seems to be immersed in a very spacious holographic field, and the sounds have gained a lot of meat and thickness, especially the bass, which is now showing some occasional rumble, and a lot of swagger, not to mention attitude--The entire sound-field is now feeling rather bold and bellyful! The V3 has excellent detail-retrieving abilities, and feels already like an entirely different beast than it did in the first few minutes (out of the box)... And the vocals, as well as notes from pianos and guitar strings... umm hold it!!
Now Wait a minute!! I promised that this is not going to be a "first impressions" review. I really shouldn't do one yet, because I'm sensing that there is a lot more audio goodness to come... So excuse me while I refuse to get ahead of myself...
Here is some info that does not sound premature to me: is this a keeper? Abso-friggin'-lutely!
And so far, I have been playing it with my rather humble Cayin RU6 dongle hooked up to my Macbook Pro listening to Roon and Amazon HD...Wait till I hook it up to one of the desktop rigs and allow it to "cook" for a few days...
