Know before you buy
The two-box configuration separates the sensitive audio circuitry from the power supply. This physical isolation is critical for minimizing electromagnetic interference, which ensures a cleaner, more precise signal path.
Yes, the NAC 552 DR supports both DIN and RCA connections. Two of the inputs are specifically configurable for RCA, allowing you to integrate a variety of source components into your system.
The internal sub-chassis is mounted on coil springs to isolate the delicate electronic components from mechanical vibrations. This prevents microphonic interference, which can otherwise color the sound and degrade clarity.
Yes, the NAC 552 DR includes an AV bypass mode. This allows you to integrate the preamplifier into an existing AV system, letting you use your high-end stereo speakers for both music and home cinema without complex re-cabling.
DR stands for Discrete Regulator. This technology provides a highly stable, low-noise power supply to the sensitive audio circuits, which is essential for achieving the level of detail and musicality expected from a reference-grade preamplifier.
These banks allow you to listen to one source while simultaneously recording from another. This provides significant flexibility for users who still utilize analog recording equipment or need to route signals to secondary systems.
