A little late in responding but I have been out of the audiophile game while I moved. I have to say that the Joseph Audio RM25si's are wonderful in my 2 channel music system. Incredible, in fact. I have an all B&W Nautilus 805 HT system powered by a B&K amp and an Anthem AV20 pre. That sounds good. But my JA's, powered by Plinius SA102 and a Plinius MK16 pre, with Cardas Gold Cross speaker cables, Au24 interconnects and a Theta Digital Miles CD Player is easily the standard by which I compare everything to. The sound is amazing. Warmer and sweeter than the B&W's . . . I am going to try to make a HT system with them since I can't have both anymore. :(
