Uneven speaker volume output

It may help some if you post your equipment. For example when you first try swapping the left and right speaker wires, if your preamp/receiver has a stereo/mono switch, set it to mono. Try the switch(st/mono) first just in case. If the sound balances out to equal, that should rule out the speakers, and power amp if it applies. On a preamp, switch the left and right inputs from your Cd player. Also the left and right outputs from the preamp outputs to your amp. If the same speaker still has a louder volume, that should rule the preamp out. If the opposite speaker gets louder, that would point toward the preamp. Do the same with your power amp. Switch the left and right inputs, and the left and right speaker outputs. If it stays the same same, the power amp should be ok. If the opposite speaker gets louder, that would point to the power amp. Only try one component at a time. There are to many unknowns now.

Hifihvn: Your help with this issue is much appreciated. Narrowed problem down to use of balanced ICS between amp and pre. Now to figure out which is the culprit. In the meantime, have switched to a pair of single ended cables that are working just fine. To my ears, no difference. Again, thanks for taking the time to help me out.Your advice helped to approach this more rationally than what might have been. Regards, maleja.

Rdavwhitaker: Response to Hifihvn goes out to you as well.

Muchas Gracias, maleja.

Glad to help, and glad you've found a work around while you figure out the culprit. Happy listening.
