If you read the sonic traits i have listed, i would call all 3 outlets i use together, NCF, Black and SE all top contenders.
They each sound different and i would call any worst or better, top notch sound from each but due to their different sonic traits and presentations, each could synergise better that the other in any given system.
I would list it as:
1)NCF - most detailed, organic, rich, full, with best high frequencies tad leaning towards a warmer, calmer mid-centric presentation. Bass does not go as low as the black.
2)Black - Very detailed, more laid back, quiet organised sound at an expense of finer and more present HF information, less midrange energy but deepest bass of the lot. Think of it as a NCF but subtracting from the fuller midrange (and leanng out this region) so as to stretch and kneading this region down toward the low regions of the frequencies.
3)Detailed, overall most balanced but less high end brilliance, micro detail and organic sound than the NCF. Not as organised and distant presentation as the black so you get more midrange energy but can be a little harder sounding and a notch below than the other 2 contenders. There seems to be less of a sonic trait bias of the lot.
