Previously I had a Denon 1000 .... this was for a price quite good. LS are Quadral M30 front plus the corresponding Center and surround by Quadral. The spaciousness ... the location of individual instruments in stereo mode are just the best! Sure, there are also around 500, - Euro between the two devices .... but who really paid off. Optics is to exceed at Marantz barely. Processing is also performed flawlessly (a little plastic is ... hardly bothers me ...) AV Sound: also very good ... forcefully. Calibration and connection is very easy, due to the class-menu. BUY !!!
