NAD C 328 Integrated Amplifier

NAD C 328 Integrated Amplifier

The NAD C 328 is a flagship hybrid digital‑analog integrated amplifier that blends classic audio craftsmanship with modern digital versatility. Designed for audiophiles who demand both pristine sound and flexible connectivity, the C 328 delivers exceptional performance across a wide range of source materials.

Core Architecture & Power Delivery

The heart of the C 328 is its dual‑stage Class‑A/B power section, engineered to provide up to 210 W per channel into 8 Ω**. This robust output ensures that even demanding speakers receive clean, distortion‑free amplification. The amplifier’s low total harmonic distortion (0.005 %) and high signal‑to‑noise ratio (100 dB) guarantee that every nuance of the music is reproduced with fidelity.

Key electrical characteristics include:

• Power Output: 210 W per channel at 8 Ω, 150 W at 4 Ω, and 80 W at 16 Ω.
• Signal‑to‑Noise Ratio: 100 dB.
• Total Harmonic Distortion: 0.005 % (typical).
• Frequency Response: 20 Hz – 20 kHz ±0.5 dB.

Hybrid Digital‑Analog Design

The C 328 incorporates a high‑performance built‑in DAC (Digital-to-Analog Converter) that supports up to 32‑bit/384 kHz audio and DSD256. This digital stage is complemented by an analog preamp section that preserves the warmth and depth characteristic of NAD’s analog heritage.

By combining these two domains, the amplifier offers:

• Seamless Digital Integration: Direct input from USB, optical (TOSLINK), coaxial, and Bluetooth sources.
• Analog Flexibility: Phono preamp for turntables, RCA line inputs, and balanced XLR connections.
• High‑Resolution Audio Support: Native playback of FLAC, WAV, ALAC, and other lossless formats.

Connectivity & Control Features

The C 328 is designed for effortless integration into any audio setup:

• Bluetooth® 5.0 with aptX HD support, enabling high‑quality wireless streaming.
• USB Input: Connect a computer or external DAC directly to the amplifier.
• TOSLINK & Coaxial Digital Inputs: For optical and coaxial sources such as Blu‑ray players or network streamers.
• RCA Line Inputs: Standard analog connections for CD players, mixers, or other audio equipment.
Phono Input (RIAA Level): Allows direct connection of a turntable without an external preamp.
• XLR Balanced Inputs: Ideal for professional audio setups and studio monitoring.
• Remote Control: Includes a dedicated remote for volume, source selection, and Bluetooth pairing.

Design & Build Quality

The C 328 showcases NAD’s signature minimalist aesthetic. Its chassis is constructed from high‑grade aluminum with a matte finish that resists fingerprints and dust accumulation. The front panel features a clean layout of input selectors, volume knobs, and indicator LEDs.

• Dimensions: 12 in (W) × 4 in (H) × 6 in (D).
• Weight: Approximately 15 kg.
• Materials: Aluminum housing, polypropylene front panel, and premium electronic components.

Audio Performance & Sound Signature

The C 328 delivers a balanced soundstage with precise imaging and dynamic range. Its hybrid architecture ensures that:

• Low‑Frequency Response: Tight, controlled bass without overemphasis.
• Midrange Clarity: Clear vocal presence and instrument separation.
• High‑Frequency Detail: Smooth treble with minimal harshness.

A typical listening experience involves a natural, engaging sound that feels both intimate and expansive. The amplifier’s low distortion levels preserve the integrity of complex arrangements, while its ample headroom accommodates high‑energy tracks without clipping.

Versatility Across Audio Systems

The C 328 is engineered to fit seamlessly into a variety of audio environments:

• Home Theater Integration: Pair with a receiver or use as the main amplifier for a surround‑sound setup.
• Hi‑Fi Stereo System: Combine with high‑quality speakers to experience pure stereo bliss.
• Professional Studio Use: Balanced XLR inputs and low distortion make it suitable for monitoring tasks.
• Portable Audio Streaming: Bluetooth connectivity allows for wireless listening in living rooms or bedrooms.

Software & Firmware Updates

NAD provides firmware updates that enhance functionality and improve compatibility with new audio formats. Users can download updates via the NAD website and install them through the USB port, ensuring the amplifier remains current with evolving digital standards.

Conclusion

The NAD C 328 Integrated Amplifier stands out as a versatile, high‑performance audio solution that bridges analog warmth with digital precision. Its robust power delivery, comprehensive connectivity options, and meticulous design make it an ideal choice for audiophiles seeking both depth of sound and modern convenience.
