Wierd Imaging Problem


I have a problem with imaging in stereo and in movies.My right speaker is not as detailed than the left.When swapping speakers the problem stays to the right speaker.

The soundstage all sounds correct.The voice is in the middle and nevers goes to the left or right of center.The left speaker sounds detailed and the right has a loss of detail whether in stereo or for movies.

I have changed all wiring and IC's.No change.

Now for the starngest part of all.The loss of detail in the right speaker is always present on all sources when I first turn everything on.After awhile and it may take a hour ,the right speaker comes back into focus and the loss of detail is not present.There is no pop or clicks it just becomes correct. I have another set of speakers that I used to tst with and the same thing happens.

I have another receiver that if I use it, it still happens with that receiver .Both of my receivers are around 10 years old.I have bassically replaced everything but still get the same problem.

I am down to thinking that both receivers are going bad.Unlikely but possible.

One of the receivers had a center channel going out and I re-soldered the relay on that receiver along with a lot of other solder joints so maybe I damaged something on that receiver.I then bought the other receiver used for testing my problem only to have the same problem.At a loss here guys.Any help appreciated.

Can you explain what the chain of components looks like in your system, from source to speakers? Can you also explain the type of Interconnects that are being used between all your components (ie.. All RCA or mixed XLR/RCA ..etc)? How about speaker wires, banana clips or spades or bare wire? How old is the speaker wire?

The problem you describe sounds similar to phasing / polarity reversal or copper cable oxidation issue somewhere in the signal chain.

You mention that the issue remains when speakers were swapped so I would skip them for now in the process of elimination.

I believe you mention that the issue exists when changing out receivers but may have switched sides. I would probably skip them as the possible issue as well, for now.

Now my next question would be focused on ALL the cabling and if it remained the same during the above tests you performed? When you started changing out cables did you do it one cable or cable pair at a time using the same source or did you rip and replace all cables? How feasible would it be for you to goto radio shack and pick up enough cheapo interconnects to complete the whole connection chain for one source to your amp/receiver and speakers? You can probably walk out of the store for under $25 to perform this test and it would be cheaper then looking for more primary components.

Good luck
