Some Strange Behavior From a Hegel 360

OK, here’s a strange one- please jump in. Just purchased a Hegel 360 to power my Revel 228s. Upper bass was excellent. Lower bass strangely lacking.   With the same recordings a good friend was getting much better bass with his Kinke Studio EX-M1 and 1.7 Maggies which aren’t known for their deep low end.  We ran his amp through my system and the bass was robust but clearly defined as it should have been- so no problem with cables, other components or speakers. Double checked all connections with the 360- everything was fine. My friend suggested we switch polarity via a speaker connection. The difference was rather amazing. Bass was now there and overall sound improved significantly- almost the opposite of what you’d expect. Any thoughts? On a related note, I’ve contacted Hegel a number of times about this issue- no response. The only support link I can find is the general info@Hegel link on the Hegel website. Any thoughts on Hegel tech support or ideas on reaching them? Thanks for your thoughts...

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

are you changing one speaker only or both speakers?

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.
