Question about Teufel Ultima 40 Aktiv 3

The Ultima 40 Active 3 does not require an external preamplifier as it has an integrated Class D amplifier with a total output of 260 watts. You can connect audio devices directly via the existing connections: HDMI ARC/CEC, digital optical input, stereo RCA input or Bluetooth aptX. If you want to use a DAC with display, you can connect it via the optical or RCA input - but an additional preamplifier is not required.
