Marantz PM7005 vs PM8006 Review

If you need a product to enhance your listening experiences across devices, you may want to invest in an amplifier. Amplifiers strengthen signals and currents from your audio devices to deliver higher sound quality and louder sound. Marantz makes two very similar amplifiers that you should be aware of, with a few key differences that set each product apart. Let’s take a look at both of these products, and see which one would be the best fit for your needs!

Marantz PM7005 Amplifier

The Marantz PM7005 Amplifier comes with a sleek design, and weighs only 22 pounds. This product comes with current feedback, which is designed to lower distortion but maintain great fidelity. This product comes with 2 channels, each delivering 60 watts in 8 ohm loads per channel. The Marantz PM7005 also incorporates a USB-B port for computer use, as well as DAC-mode.

The Marantz PM7005 also has discrete circuitry, which includes precision circuit elements featured on a compact sub-board. This product does not use op-amp integrated circuits. Discrete circuits allow for a purer sound and a wider frequency response.

The phono amp, power amplifier, and digital audio blocks have HDAM modules as well, which are Marantz’s most recently developed modules. This comes with HDAM-SA3 circuitry that provides a wide band response, as well as clear treble and 10 dB of noise.

The Marantz PM7005 has a Source Direct option, which allows you to bypass tone and balance controls. This gives your signal a faster path for louder, better sound. Analog mode is also available, as well as conversion from digital to analog. The CS4398 D/A converter makes this possible. Along with all of these features, the Marantz PM7005 comes with brass speaker terminals that are gold plated for optimal sound.

More features of the Marantz PM7005 Amplifier

  • 2 Channels
  • 5 Hz to 100 kHz frequency response
  • 170 W power consumption rate
  • 17.32 by 14.92 by 4.92 inch dimensions

Marantz PM8006 Amplifier

The Marantz PM8006 amplifier shares many of the same features as the previous product, including a sleek design with a weight of only 26.5 pounds. This product also comes with current feedback to provide great sound quality, and with 2 channels as the former product did. These channels deliver 70 W per 8 ohm loads.

This product also comes with discreet circuitry, as well as symmetrical circuits that are capable of providing optimal imaging. The Marantz PM8006 comes with a Marantz Musical Phono EQ preamp stage. This stage is designed to amplify vinyl record sound with accuracy. This product also comes with HDAM-SA3 circuits, and brass terminals with silver plating.

The Marantz PM8006 minimizes Negative Feedback to provide sonic transparency and a high through-rate. This product can also work easily with loudspeaker loads that are typically more difficult. This product’s HDAM technology is also enhanced, allowing for higher quality sound, through better Slew Rate and sound output.

This product comes with a Musical Phono EQ, much like the former product, for great playback through 2-stage amplification. AC coupling capacitors aren’t needed due to this products usage of HDAM technology and junction gate field-effect transistors. This product also utilizes a toroidal transformer for better power capacity and lower electromagnetic radiation, helping to create better sound quality.

More features of the Marantz PM8006 Amplifier

  • 2 Channels
  • 5 Hz to 100 kHz frequency response
  • 220 W power consumption rate
  • 18.3 by 21.5 by 8.8 inch dimensions


Amplifiers are great for helping you achieve the best sound experience with many varieties of input devices. If you need a product that offers a smaller size and lighter weight, as well as precision discrete circuitry, HDAM modules, and Source Direct options, then the Marantz PM7005 amplifier is for you. Alternatively, if you need a product that offers higher channel wattage, is slightly larger in size, with a toroidal transformer and HDAM modules, then the Marantz PM8006 is for you. Both of these products deliver great sound, making either an excellent option for a new amplifier.
