[font="ProximaNova-Semibold, arial, verdana, sans-serif"]Update. I have had both pairs of speakers (the Q Acoustics 2020's and 3020's) running off the Marantz PM6004 amplifier and I can report that the amp has survived the Christmas holidays with no obvious ill effects. The amp is not running noticably warmer than it was with one pair of speakers and has not cut out once. I admit I was a little nervous ignoring some of the advice given here and in the user manual BUT these speakers really do sound great together, I thought it was worth a gamble. Perhaps the amp would not like it if I cranked up the volume too much but I don't listen to my music really loud anyway. IF the life of my Marantz is cut short I will probably invest in an amp that is built to cope with such a set up as I do like the sound of this combination of speakers very much and the 3020's sit very nicely on top of the 2020's.[/font]
