Well my blackwoods are definitely akin to HD-650 interms of warmth, but better in every aspect (except for transparency and soundstage). THe blackwoods are very similar to my LCD-2, but slightly smoother, the mids are a bit richer, the highs are similar in quantity but the LCD-2 is a bit more airy (probably hearing this because of closed vs open), bass is similar, LCD-2 has slight more extension but blackwoods have more impact, both are just as tight. I find it amazing that the lcd-2 sounds slightly grainy compared to the blackwood. I actually like it more than any of my headphones right now, its very very musical and yet has a very good level of detail. The only two things that I can point out to be the problem for this fantastic headphone is that it lacks a bit of presence in the top octave which makes it lack a bit of airiness compared to the other phones that I have, and the soundstage is slightly smaller (but exceptional for closed backs). Really enjoying my pair, I tried other planar closed backs such as the audeze el-8 and the XC, they sound artificial and distant compared to the organic and lush blackwood, this headphone is a keeper.
