I really doubt that sfb21 (the frequency range above 16 kHz will reveal transcoding artifacts).If it's (1), I'd imagine both settings would be essentially indistinguishable, already having a good deal of safety margin beyond the threshold of transparency, which is probably nearer to -V3 or -V2, and again, in real music, whether -Y is used or not, is unlikely to make an audible difference.For case (2), -V3 or -V2 might be a little risky, because the inaccuracy of two encoding steps is being combined, and they're aimed at pretty much being just enough to ensure transparency (problem samples aside), with little margin of safety when encoding from the original, lossless source. Having said that, for a number of uses I've happily done just that sort of thing and not noticed a problem, but if you're DJing, you don't want to be taking chances.
2) for dj sets, available for free on Soundcloud, none use VBR V0, most are 320k, none is using lame 3.99.51) for any tracks found on Soundcloud that are flaci use XRECODE with external Lame 3.99.5 x64
