Well the dealer that was trying to sell me a Rotel 1057 for my 4ohm Auditors said there would be know problem driving them with it. He also said don't buy the Denon 2308ci because it won't last 9 months under the 4ohm load and won't have the sq as the Rotel. OK this is a response I get from Rotel >>>>The RSX-1057 is only capable of speakers with 8 ohm minimum speakers. It is not designed to dissipate the heat that would be generated from 4 or 6 ohm loads. This could result in damage to the receiver.<<<<< It is getting very frustrating finding an AVR to drive these speakers. I would prefer to keep them so please help on choosing an AVR for me. I watch HD TV,ocassional movie and listen to music.
