Just got my PS1000 delivered:) Second hand, but really like new.
I'm listening to them right now, itunes (24/96 m4a) -> audirvana plus -> M2tech-> Burson audio dac -Burson Audio HA160 (QED silver genesis cable, supra power cable).
the bass and medium are fantastic, same goes for the very well defined high, but they are a bit on the bright side, at least with my setup. it's not a surprise though, everything that i've read pointed my in that direction, the burson audio HA160 are not perfect for them, they tend to give a quite agressive high frequency.
though, one thing I can already see if how wide the scene is, that's really gorgeous.
