Can't wait to read your furthur comments.
In my system PS1000 has more microdetails than HE6 (ofcourse my el34 push pull amp can drive He6 properly.) And the transparency is also better, I can hear the depth of soundstage clearer.
And for transient response, PS1000 is also better than He6.
PS. Now i use 8 wires norn cable connecting from speaker tab of my amp to drive He6.
