Can only agree with the previous speakers: This is a top amplifier !! Operate it to my Teufel Ultima 40 MK2 tower speaker. Have this connected via bi-wiring. (After a hearing test this cabling was clearly better.) The amplifier looks wertig, but the front and the volume control is made of plastic. For the price you have to make cuts here .... Function, connections and the remote control, however, are great!
