No soundstage problems here, don't know what to tell you
I don't think anyone said you did, or that you should for that matter. I was trying to help the OP, not throwing shade on you or your system.
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.
