I've currently got a Pioneer LX55 receiver hooked up to B&W MT60D speakers. I listen to about 30% music and the remainder of the time I use the system with blu rays. I am happy with the sound of the system... But am curious about how it might sound with a receiver with fewer settings to try and get right. I'm considering the Rotel RSX 1550 as an alternative to the Pioneer and wondered whether anyone has any experience of this and can offer any thoughts or advice?
