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

Good morning. You were all right! Thank you so much, I appreciate your help. My Modwright is an older model without the high/low pass switch and has the L and R terminals oriented in the same direction rather than mirrored like the more recent ones. I put my cables on by feel and, without a manual available, was using one the on-line version which had the mirrored arrangement. So, the polarity was reversed on the left side. Anyway, blessings and thank you's - enjoy the tunes and the long weekend! |
@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. 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 |
@facten From the LS100 manual: "Design is phase inverting and this may be addressed by reversing polarity at both speaker cables, either at amp(s) or speakers." |
