Occasional Sound Imbalance Issue


I posted an issue a while back where I had an issue with what I thought at first was due to my room sucking out higher frequencies from the right side of the sound. After jumping through hoops to isolate the issue, ruling out the room and my gear as causing the issue, I had concluded that it was actually slight imbalances in the source material.

This turned out not to be the case. The issue sometimes returns, but only when I physically move ANY of my components (even slightly), or mess with my cabling (even slightly). When the problem returns, it takes hours of trial and error fiddling to get rid of it. When the problem is resolved, it stays resolved for as long as I don’t touch any of my components or cabling. When re-arranging ANY of my vibration control footers that my components rest on, the problem will promptly return, every time.

This issue drives be NUTS.... Suggesting the issue is with balance is misleading - it’s more subtle than that, but at the same time very obvious (but only on certain songs which is why for a while I believed the issue to be related to source material). At times the issue is very subtle when it manifests, and at other times it’s extreme. But in all cases, even non-audiophile members of my family (which is everyone else...) can detect the issue. It’s like the air and ambience around a singer’s voice is present on the left of the singer, but not on the right, which is veiled in comparison. Also, when the problem resolves, the vocals in general sound more open and confident - possibly simply due to the ambience and air on the right side of the vocals being restored.

What’s new vs my prior thread is that I now understand the issue to be transitory, and related to physically moving my gear or cables, even slightly. In my prior thread on the issue I’ve gone through the process of ruling out any of my devices specifically contributing to the issue, testing in isolation etc and the issue still remaining (I reversed my amp’s output speaker cables too, to see if the problem would follow the output).

My cabling is a bit of a mess. Currently I have everything but my Rel subs (which arrived only very recently so nothing to do with the issue) powered by my Torus RM20, which in turn is connected to a dedicated 20A circuit. I have a photo of my rat’s nest of cables uploaded to my system pics on Audiogon. My full system details and photos are posted there as well for reference.  I'd suspect my mess of cables are to blame with EMF buildup or something, but the weird thing is that just gently moving any component, even while on and playing music, can cause the issue to show up (I suppose gently moving a component moves it's cables as well however).

On a less revealing system or components, the issue is much harder to detect. Removing my PhoenixUSB reclocker from the system for example makes it a bit harder to detect, but it’s still obvious. I’d probably never know about this issue if I had my prior speaker cables, but with my Nordost Valhalla 2’s any issue is readily apparent.

Has anyone heard of anything like this before, and have an explanation of what is happening? And suggestions on ways to prevent it from happening?  I really hate this issue, especially because it is a big, big impediment to the tweaking/testing process.

Wow. This sounds like a really difficult issue.
 

If this happened to me I would allow the system to achieve balance and then see if I could not touch it for as many years as possible. This sounds like something you could spend an enormous amount of time diagnosing and not figure out. But if you upgrade your system on average every say 5 or 7 years… then, it will disappear at some point when you swap something out. Then, you may figure it out, or not… but it will be gone.

 

To me, life is too short to spend too much time on something that can be gotten rid of by fiddling for a few minutes and not touching again. 

Could be changes in ear pressure when you get out of your chair? What happens if you stay sitting down and someone else moves something? 

@ghdprentice ​​@noromance , sorry I was unclear on one critical point: it does NOT take just a few minutes to clear up the issue. It takes hours, and days in some cases, to resolve. One thing that often clears the issue is shutting off the switch to my Torus RM20 that powers everything, and leaving it alone for 5-6 hours. However I’ve just now done that I’m not there yet! All it takes is a gentle movement of any component and the problem will occur, but a quick fiddle unfortunately does it resolve the issue.

@holmz I’d agree it is likely a connection issue if not for the fact that I can move any component in my system and the problem materializes instantly! Very frustrating.

Also of note is that it is not related to restarting my digital devices, as the issue happens when moving a device or cable while the system remains on and is playing music. Very frustrating! It’s such a relief when it gets back to optimal sound.

My guess is it’s somehow related to my cabling. I have two unnecessarily long power cords (3m) but I believe I’ve laid them out in as clean a way as possible with minimal coiling.

I guess one test I could do is buy 5 1m cheap generic cords and see if the problem disappears.

@ddd1 no it’s not ear pressure.  When the problem is there it remains until I do something to eventually address it.  And when the problem goes away, it is gone for good until I move something in my system.

I mentioned this but to elaborate, once the problem happens, when I move things around again, the unbalance effect changes.  Gets better or way, way worse, but doesn’t fix without leaving the system totally unpowered (not just off) for hours.  Sometimes the issue is very subtle and other times it’s extreme.  That said, I’ve been trying to get back to normal currently leaving unpowered for hours, but it didn’t help this particular time…. Which prompted me to vent on this thread!

Also, it’s not that I’m nuts :) I almost started thinking I may be, which is why I involved the family in a blind test and asked them to describe any issues they heard, without telling them…
