Nobody said it was super bad, and nobody said others aren't over priced, they are. But it's like what's said previous, why would you spend money on this just as an amp. Other all in one solutions are better overall, or you can spend left overs on a dedicated amp.
Basically, from what I've read, if you're after the warm sound of the famed 650, don't get the 2015 version.
So if I have lcd2, t1, hd800, grado rs1, the hd650 doesn't fit in any niche use, am I right?
