Definitely strange that you had a similar experience with your 160- reversing polarity usually means a much diminished, sound thin reproduction- which is what I'm hearing with correct polarity. Seems the gentleman who bought your amp discovered what I've discovered. With polarity reversed my bass increased significantly, imaging became a bit more diffuse but not unacceptably so and the soundstage broadened to a more concert-like tapestry that your might hear if your closed your eyes during a live performance at really good venue. A bit of brightness vanished from the top end and there was a much greater balance between top and bottom. Right now the amp is sounding great. Go figure.
Glad to hear the situation was improved.
sorry to hear Hegel support was ineffective or unattainable... so far.
from these pages I've read time and again, exchanging polarities on speaker cables off an amp may resolve things. Conrad Johnson was a prominent player in this sort of seeming aberration some time back.
why something like this happens at all mystifies me, especially given the costs of some of these amps.
likely though the amp guys will blame it on the speaker guys. lol
Appreciate all the responses... Compared to many folks on these forums my tech chops are somewhat limited; but, I've been told that switching cables on both speakers will simply take me back to a situation of "correct" polarity. Good advice about not trying to fix it- that's pretty much where I'm at. Such a puzzle though- really would like an explanation. I'd also like to know why Hegel's support has been non-existent. That may bother me more than the amp's behavior.
Hello all, thanks for weighing in...
I'm changing only one speaker connection. Somewhat disconcerting that a person assembling a $6k amp would be so careless or disinterested in properly putting it together. Did I worry a bit that these are coming out of China instead of Norway- maybe a bit. I'm not happy that Hegel isn't more transparent about its Chinese connection; but I know some very good stuff is coming out of China including my DAC. For those who've wondered, there's nary a mention of reversed polarity in anything Hegel's put out. For what it's worth, my latest listening was very rewarding- with reversed polarity. My system was doing all I'd expect out of it. A good night of tunes... Again, thanks to all for their thoughts.
