So, you reversed the cable, at one end, or at both? Did you try another cable? If you only reverse the cable at one end, you verified that the power amp's input controls are set the same, but didn't do anything to verify the preamp's output. You would need to use only one cable, connected to one channel of the power amp- this eliminates one variable (the power amp's other channel) and you still need to remove the other variable (the cable for the second channel).\n\nThe imbalance being more noticeable at low levels is natural- try one cable from each channel (or a completely different pair) and see if it still does this.\n\nIf you can find an example of the integrated amp having these problems, let us know- I doubt they have been a problem.\n\nBTW- the pot isn't sloppy, but it may not be tracking properly. Unfortunately, art manufacturing isn't perfect and end users as well as equipment manufacturers are at the mercy of chance or human failings.\n\nI did all combinations actually yesterday, headphone (on the P5 preamp), single cable, different cables, I even swap power amp (putting the output to the Krell); before I phoned AA and returned them. I let the sales folks know about this issue and asked him to try it on their demo unit. No idea where it will lead to though.
