I was with two 627 Burson OPA on a brown dog just before to have it and the sound was quite good but with the sennheiser I needed to play with the equaliser and some Audacious plugin (I'm on Linux with a HRT dac and configured the bitperfect hability of my OS). With the V5i, I deactivated all plugin and the equaliser and have more space (than the spacializer plugin do), it's far more realistic, sharper (I like when it's sharp especialy for vocal parts in rock and opera, that's why I use Voskhod valves, like the Mullard for the rock but it's too smooth for me after 1 or 2 hours). You don't need to think twice where were the instrument in the scene...
Personnaly, when I make a change I use the song Joline of Dolly Parton : here, the voice is sharp, the guitars from left and right are perfectly placed, bass are details, just perfect as I have it in my head. Another thing, I judged that some instrument are better dissociated and I can heard some sounds that I never heard before.
That's my own experience and I just have it for two days, so it needs burnin but normaly it will be more accurate with time, but the best thing : it's twice cheaper than the original V5 and you can put it in very easily in the little dot.
. Hope it makes a big change with the two single 627 in the brown dog (which have already an amazing sound).
