Marantz PM6007 vs Cambridge CXA81 – Best Mini Stereo Amplifier

Thanks to numerous mini-amplifiers, it is possible to set up a stereo speaker system without requiring high amounts of space.

The Marantz PM6007 and Cambridge CXA81 offer two different experiences: Marantz offers an interesting presentation as it trades the smoothness in its predecessor to add rhythmic punches, accuracy, and clarity; resulting in songs that have greater presence. The CXA81 will give the impression of being firmly in the driving seat regardless of the speakers you use, and gives songs plenty of punch as you need them.

Marantz PM6007 vs. Cambridge CXA81 – How do they compare?


While both amplifiers have a familiar build and have little separating them in appearance from other options, the CXA61 is a solid option that feels superior to its rivals – including the Marantz PM6007.

The Cambridge CXA61 comes with a USB type B connection port, alongside the usual optical digital and coaxial digital inputs on its rear panel. Marantz, on the other hand, implements the same features in the PM6007 that were in its predecessor without much enhancements, although its appearance will appeal to traditional hi-fi enthusiasts. The biggest difference in its design is the lack of a USB connection port, as well as the lack of Bluetooth connectivity.

The addition of USB and Bluetooth connectivity in the Cambridge CXA61 makes it the winner of this round.


The most prominent indicator of the changes in the Marantz PM6007 is in the performance, with a distinct full-bodied and smooth sound output. All the textures in the audio take on additional levels of tangibility, but one drawback is the lack of solid vocal delivery.

On the other hand, the CXA61 offers numerous improvements and tweaks in its audio quality, and the result is a more playful and transparent sonic output. The tonal balance is impressive, offering the best mediation between refinement and attack, which makes it work excellently across different music genres, and its soundstage is clear and expansive to offer plenty of stability to both the vocals and instruments.

The Cambridge CXA61 offers better sound quality overall and a wider soundstage compared to the Marantz PM6007.

Feature set

In the Cambridge CXA61, you will find a new DAC chip that allows it to be compatible with up to DSD 256 data streams, as well as 32-bit /384kHz PCM files. This is quite a comprehensive range, and covers almost any file type that you may use. Aside from this, it also has in-built Bluetooth functionality and an RS232 port. On the analog side, each channel has a 60W power output, and there are several ports – one 3.5mm jack on the front for portable music players, and four stereo RCA inputs on the rear.

In the Marantz PM6007, the biggest change is the new DAC that is based on an AK4490 chip. You can select one of its two filters when listening to music, allowing you to choose what fits best. There is plenty of consistency across its connections with the phono stage, headphone output, and DAC performing well despite its precision and clarity sacrifices. The 6.3mm headphone output in the front and the phono stage work together to deliver a punchy sound as well, but it lacks the sparkle that the line-level offers.

The Cambridge CXA61 wins due to its superior sound quality and connectivity options.

Cambridge CXA81

While its design may look like an uninspiring slab of silver, its performance exceeds expectations thanks to its distinct lively sound.

According to Andrew Gibbons, playing the guitar is fun but it will take a few months before you can come up with a creative expression. Gibbons is a guitar instructor and has been teaching University music programs for over a decade, when it comes to playing the guitar a lot of factors come into play that determines the type of sounds produced. The guitarist must consider the guitar's neck and body shape, weight, and string type, the amp is also a primary determinant of the sounds produced and that is why Gibbons has created extensive excerpts detailing on the delicate topic. Guitarists must also pick a pose, be it the pro, wizard, hipster, or the old master.
