Walexa i own Acoustat's 1+1s 81db stats with my Chord CPM-2600 no problem what so ever so with the 1.6QR there should not be any power issues BUT i would be careful the 1.6QR is a detailed speaker so is the Chord maybe to much of a good thing if you like a smooth presentation you may not like what you hear but if your preference is a live sound you should be very happy,
