The Marantz PM6007 is the latest iteration of the long-running and highly regarded PM series from Marantz, a brand renowned for producing high-fidelity audio components. Priced at $699, this integrated stereo amplifier is positioned as an entry-level high-performance amplifier, ideal for audiophiles seeking both analog and digital versatility in a compact form. With a clean design, quality components, and enhancements over its predecessor (the PM6006), the PM6007 is a strong contender in its category. This review dives deep into its features, sound quality, usability, and value proposition.
Design and Build Quality
The Marantz PM6007 sports a minimalist yet elegant design, staying true to Marantz’s aesthetic heritage. It features a solid aluminum front panel, with neatly arranged buttons and knobs that contribute to its premium look. The build quality is sturdy, with a substantial weight that reflects the quality of internal components. Despite its relatively small size, the unit feels dense and well-constructed, with a layout that is both practical and user-friendly.
- Dimensions: The unit’s footprint (17.3 x 14.1 x 4.1 inches) makes it a space-friendly addition to most audio setups.
- Weight: At 17.6 pounds, it’s portable enough for easy placement, yet heavy enough to suggest robust internal engineering.
The front panel is intuitive, with knobs for volume, bass, treble, balance, and input selection. The back panel is where the action really happens, housing a variety of analog and digital inputs. The layout is clean, and ports are well-labeled, making the process of connecting multiple devices hassle-free.
Audio Features and Specifications
2.1. Amplification and Power Output
The PM6007 uses Current Feedback Topology, a characteristic feature in Marantz amplifiers, which ensures high-speed, detailed sound reproduction. Its output power is rated at:
- 45 watts per channel into 8 ohms
- 60 watts per channel into 4 ohms
This power output is modest compared to some high-end amplifiers, but it is more than sufficient for most small to mid-sized rooms. The damping factor of 100 indicates that the amplifier has good control over speaker movements, ensuring tight and accurate bass.
- Total Harmonic Distortion (THD): 0.08%, which is commendable, as this low distortion level translates into clear, undistorted sound.
- Frequency Response: 10 Hz to 70 kHz, far beyond the typical human hearing range, implying that this amplifier is capable of handling a wide range of frequencies, offering crisp highs and rich lows.
Analog and Digital Connectivity
One of the PM6007’s key strengths is its versatility in connectivity. It offers five audio inputs and a range of digital options:
- Analog Inputs: Five audio inputs, including a dedicated MM (Moving Magnet) phono input for turntables. The phono stage is based on the technology used in the higher-end PM700N model, resulting in lower distortion and noise, which vinyl enthusiasts will appreciate.
- Digital Inputs:
- Two optical and one coaxial input support a 192 kHz/24-bit sample rate, enabling high-resolution audio playback. This makes the PM6007 a great choice for connecting CD players, streamers, and TVs.
- New AK4490 DAC (Digital to Analog Converter): The PM6007 uses this advanced DAC to improve sound quality, offering high-resolution compatibility for enhanced digital performance.
Digital Filters
Marantz has introduced two new digital filters, which are unique to the PM6007. These filters allow the user to adjust how digital signals are processed, tuning the sound based on personal preferences:
- Filter 1: Prioritizes precision, delivering tight, controlled sound.
- Filter 2: Focuses on depth, producing a warmer and more immersive soundstage.
This feature is particularly beneficial for those who listen to different types of digital media and want to tailor their listening experience based on the source.
Subwoofer Output
The inclusion of a dedicated subwoofer output is a welcome addition. This feature allows users to connect an active subwoofer for deeper bass response, making the PM6007 suitable for home theater setups or audiophiles who desire more low-end punch. Additionally, the amplifier supports two sets of speaker outputs, which can be controlled individually, enabling multi-room audio or speaker bi-wiring.
Performance and Sound Quality
General Sound Profile
- Bass: The PM6007’s bass performance is noteworthy. Despite its relatively modest power output, the bass is punchy and well-controlled. The amplifier’s damping factor helps prevent the bass from becoming boomy or uncontrolled, especially when paired with a subwoofer.
- Midrange: The midrange is where the PM6007 truly excels. Vocals and instruments are rendered with exceptional clarity and detail. Whether it’s the warmth of a guitar or the intimacy of a vocal performance, the amplifier brings out the subtle nuances in the music.
- Highs: The treble is crisp but never fatiguing. The PM6007 does a good job of handling high frequencies without introducing harshness or sibilance, ensuring long listening sessions remain enjoyable.
Phono Stage Performance
Vinyl enthusiasts will appreciate the improved phono pre-amp on the PM6007, which is derived from the PM700N. The noise floor is impressively low, providing a clean, uncolored sound. The phono stage enhances the natural warmth of vinyl, delivering an open, detailed sound that lets the richness of the analog medium shine through.
Digital Performance
Thanks to the AK4490 DAC, digital playback on the PM6007 is excellent. The DAC is capable of decoding high-resolution audio files, and the digital filters provide added flexibility for fine-tuning the sound. Whether you’re streaming music, playing CDs, or watching movies, the digital inputs deliver crisp, dynamic audio with little distortion or noise.
Performance with Various Speakers
The PM6007 pairs well with a variety of speakers. It can drive both 8-ohm and 4-ohm speakers effectively, making it versatile enough to handle different setups. However, it performs best with speakers that have relatively high sensitivity, as this helps compensate for the amplifier’s moderate power output. The amplifier’s tonal balance remains consistent across different speaker types, and it handles both small bookshelf speakers and larger floor-standing models with ease.
User Experience and Practicality
The Marantz PM6007 is designed with user convenience in mind. The front panel controls are responsive and intuitive, and the remote control offers easy access to all major functions, including input selection and volume control.
Setup Process
Setting up the PM6007 is straightforward, whether you’re an audio enthusiast or a beginner. The back panel is clearly labeled, making it easy to connect all your devices, including turntables, CD players, streamers, and TVs. The inclusion of multiple inputs means that you can create a highly versatile system without needing additional components.
Versatile Inputs and Outputs
- Analog and Digital Sources: With five analog audio inputs, including a phono input, and three digital inputs (two optical and one coaxial), the PM6007 can accommodate a variety of devices. Whether you’re playing vinyl, streaming music, or watching movies, this amplifier can handle it all.
- Subwoofer Output: The addition of a dedicated subwoofer output is a game-changer for users who want to enhance their system’s bass response. This feature, combined with the ability to drive two separate sets of speakers, makes the PM6007 ideal for multi-room audio setups.
Comparisons with Competitors
At its price point, the PM6007 faces stiff competition from brands like Yamaha, Cambridge Audio, and NAD. However, it stands out due to its well-rounded feature set and sound quality.
- Yamaha A-S501: Priced similarly, the Yamaha A-S501 offers more power (85W per channel) but lacks the warmth and midrange detail that Marantz is known for. The Marantz PM6007 is better suited for those who prioritize detail and musicality over sheer power.
- Cambridge Audio CXA61: The Cambridge Audio CXA61 offers similar digital features, including a high-quality DAC. However, the CXA61 is priced higher, making the Marantz PM6007 a more budget-friendly option with comparable sound quality.
Is the Marantz PM6007 Worth It?
The Marantz PM6007 is an outstanding choice for audiophiles looking for a well-balanced, high-performance amplifier under $700.
