“The DPA-1 is a stereo switching amplifier capable of 125Wpc into 8 ohms and 200Wpc into 4 ohms. The front panel offers more features than traditional power amplifiers, including selectable gain (a +6dB button), clipping indicators, a mute button, and soft-start warm-up. Both balanced and unbalanced inputs are provided. The DPA-1M is a monaural version of the same amplifier, delivering 325W into 8 ohms and 400W into 4 ohms. Both amplifiers feature a Class A input stage and a Class D output stage, based on Bruno Putzeys’ Hypex UcD module. (The DPA-1M monoblock simply bridges two of these modules for greater output power.) Sonically, both amplifiers have a lively, upbeat sound, powerful rhythmic drive, wide dynamic expression, and rock-solid visceral grip in the bottom end. ”
