Know before you buy
MDC2 stands for Modular Design Construction, which allows you to add future hardware modules to the amplifier. This means you can upgrade the unit with features like BluOS streaming or Dirac Live room correction later on without needing to replace the entire amplifier.
Yes, the C399 includes a dedicated, ultra-low-noise Moving Magnet (MM) phono stage. You can plug your turntable directly into the phono input without needing an external preamp.
The HDMI-eARC port allows you to connect your television directly to the amplifier. This lets you control the volume of the C399 using your existing TV remote and routes the audio from your TV apps through your high-quality speakers.
The C399 features a dedicated, high-performance headphone amplifier designed to drive a wide range of headphones. Its low output impedance and high voltage capability ensure it can handle demanding audiophile-grade headphones with ease.
Out of the box, the C399 does not have built-in streaming. However, you can add full BluOS high-resolution multi-room streaming by installing the optional MDC2 BluOS-D module.
This technology provides 180 watts of clean, efficient power with extremely low distortion. It ensures that the amplifier remains cool and stable while delivering a highly detailed and dynamic sound, even when driving difficult speaker loads.
