Did you physically switch speakers,or just swap cables at the amp?

Its a fault with the speakers. Could be a bad connection or crossover part, whatever, its clearly the speakers. Either that or your Prima Luna is clairvoyant and knows which speakers and which channel to decrease just to make you upset. Have you been mean to it lately? Called it any names? I mean before this started happening....
testpilot, in regards to the tubes I tried both the 7581’s and the EL34’s and in each instance I switched speakers, right to left and left to right. The lower level always followed the speaker. I’m convinced it’s something about the one Polk speaker that is causing the issue, just seams really strange. Busy day today and I didn’t have a a chance to get in touch with Polk but I plan on following up with them.
Well I procrastinated but I did end up getting in touch with Polk last week about the level imbalance. After some back and forth and a little further testing it was determined the crossover was not functioning probably. Keep in mind I’m not the original owner nor do know their age but after talking with Polk this past Friday they sent me a new crossover and I received it this morning (Tuesday), for free. Took me about 1 1/2 hours to replace and all is right with the world. Well, all is right with the speaker anyway. Kudos to Polk for standing behind their products. FWIW I’m now using KT150s and love them.
This is an interesting topic and I had an answer from the beginning on a possible issue.
I owned the as2100 always wanted the as3000, excellent SS amp, beautiful looking, anyway I think the root of your issue could have been an impedance mismatch, which is more difficult to handle by the primaluna than the SS amp.
Polk's answer about the crossover issue and sending a replacement was great
