It draws its power from a toroidal transformer and the "Ncore" Class D amplifiers from Hypex, which are also in the integrated amplifier of the same series and which, according to the data sheet, deliver 2x115 watts at 4 ohms. The AP-505 is also suitable for bi-amping and can be operated as a mono power amplifier in bridge circuit. The metal housing with the aluminum alloy sides stands on three vibration-dampening feet. Two pointer instruments provide information about the current level. The signals – for example from the USB DAC/network player NT-505 – are fed in via XLR or Cinch. The power amplifier is now available for 1500 Euro in black or silver.
