WAITAMINIT! Center stage disappeared with a Modwright KWA 150SE and Daedalus Athena V.2?!

The Madness! My Plinius SA201 presented a big beautiful well imaged stage with the Daedalus Athena V.2. It was shipped and sold. 4 days later, the Modwright KWA 150SE reco'ed by Lou Hinkey took it's place and the center stage is nowhere to be found! I've rotated cables and repositioned the speaker 6 inches back and forth and toed them in with no change. I haven't rolled in new tubes in my preamp or DAC yet...It partially refocused for a moment but now is gone, baby, gone.

Anyone out there have experience with this? I imagine it's solvable....

Help a man out, brothers and sister.

Pre: Supratek Syrah, DAC: AMR DP777SE

@big_greg "Don’t know about your unit, but my LS100 MW preamp had the phase inverted by design. Reverse polarity on speaker cables as suggested."

I have the same preamp and was never told this.

@budburma -

Aside from the LS100 I also have the KWA100SE, the speaker posts clearly indicate with red and black the connections not sure why the KWA150SE would be any different. Both units were purchased in 2011

@big_greg "

"Design is phase inverting and this may be addressed by reversing polarity at both speaker cables, either at amp(s) or speakers."

Thanks, guess I passed right over it. I haven’t had the issue originally noted with the LS100 coupled with the KWA100SE and Daedalus Argos V2s.
