Interesting comments. My L1290/2 speakers were hooked into a Rotel RMB-1066, switched for bi-amp mode, wired appropriately and I wasn't happy. On first try, it sounded pretty clean and had good low range depth but after loading up some CCR (Suzie Q) I noticed garbled output where Johns guitar seemed to dissappear on some notes. I pulled off the double cables (for amp A and amp C) and went with a single amp using the internal cross-over. Clearner but less depth of field. Currently looking for solutions to get the most of the ADS....a great little speaker
