Marantz vs NAD Specs Compared
Power and drive
The Marantz PM6007 delivers 45 watts of continuous power. Its high-current power supply and thermal compensation aim to handle demanding speakers with precision. The NAD C3030 offers 50 watts per channel into 8 ohms. It also claims over 100 watts of dynamic headroom. This HybridDigital design uses a custom power supply for stable voltage regulation. While Marantz focuses on discrete HDAM circuitry for lower distortion, NAD emphasizes raw power reserves. You get slightly more baseline wattage from NAD, but Marantz provides robust current delivery. Both units are capable drivers for most stereo setups.
Digital conversion quality
Marantz uses the reference-class AK4490 DAC in the PM6007. It supports high-resolution audio up to 192-kHz/24-bit resolution. You can choose between two selectable digital filter modes. This chip is known for wide dynamic range and accuracy. NAD employs the Texas Instruments PCM5242 DAC in the C3030. This chip ensures dynamic, jitter-free playback for digital sources. Both units include built-in digital-to-analog converters to handle modern audio files. The Marantz offers higher resolution support and user-selectable filtering. NAD provides a solid, jitter-free conversion experience. If you prioritize high-res file playback and customization, Marantz has the edge.
Physical footprint and weight
Size and weight matter for shelf placement and stand stability. The Marantz PM6007 is a slimline unit. It measures 17.3 inches wide, 4.13 inches high, and 14.6 inches deep. It weighs 23.1 pounds. The NAD C3030 is taller and heavier in dimensions but lighter overall. It measures 17.7 inches wide, 9.45 inches high, and 16.1 inches deep. It weighs only 16.1 pounds. The Marantz is shorter, which may fit better in tight vertical spaces. The NAD is lighter, making it easier to move. You need to measure your shelf height carefully for either unit.
Connectivity options
Input variety expands what you can connect. The Marantz PM6007 offers five analog inputs, one coaxial digital input, and two optical digital inputs. It also includes a subwoofer output and speaker A/B switching. The NAD C3030 adds HDMI eARC input and Bluetooth aptX HD wireless connectivity. It includes a front-panel headphone output and a subwoofer output. NAD provides more versatile digital and wireless options, including HDMI for TV audio. Marantz offers more traditional analog and optical inputs. If you use a TV or stream wirelessly, NAD is more flexible. For pure analog and optical sources, Marantz is sufficient.
Phono stage performance
Both amplifiers include built-in phono stages for MM cartridges. Marantz uses FET circuitry to simplify the signal path and lower noise. This design aims for extraordinary clarity and signal purity for vinyl. NAD features an MM phono stage with precise RIAA equalization and infrasonic noise suppression. Both units preserve the nuances of vinyl playback. Marantz highlights its low-noise FET design for purity. NAD emphasizes accurate equalization and noise suppression. Both are competent for standard moving magnet cartridges. The choice depends on your specific cartridge and desired tonal character. Neither specification clearly outperforms the other in raw data.
