ive compared my marantz to some denon model and even denon with less rms did sound louder, but marantz sound was warmer and sounded richer than denon, similar in comparision with HK, which had flatted mid and low end in comprising.
and speakers, they may not be some great but thats all i had to spend, and compared to different B&Ws, Gallos, JBLs and PSBs and few other brands that im ashamed to mention but CMs, i like them most and the price was right
now in theory i will gain new codecs with rotel but if its all, i dont see that worth spending a penny, if rotel offer better musical performance then i have reason to go for it, unfortunately i cant get both and compare so i gotta ask, that maybe someone had experienced both brands and can tell me difference that he noticed
