As far as the guy in the YouTube video from the OP's post...to each his own. I've heard Mac on a number of occasions and they sound stellar to me. Maybe not his taste...but mine for sure. Easy to listen to, engaging and effortless sound. I've heard w/ B&W and Klipsch and impressive to say the least. I can't imagine Sonus Faber not sounding good as well as many other brands too.
McIntosh -- good for show, not for sound, says dealer
