What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

  • M&K Sound speakers are frequently used as reference monitors in music and film production facilities, indicating a professional-grade accuracy.
  • The brand's Phased-Focused crossover technology is designed to create a uniform timbre balance throughout the listening room, improving the three-dimensional response from almost any position.
  • M&K Sound's Tripole speaker design combines a direct radiator for precise directional sound with a dipole for diffused sound, delivering a more immersive 360-degree soundstage.
  • M&K designs subwoofers implementing a push-pull driver configuration to reduce distortion and increase bass output, enabling a smaller cabinet size while maintaining powerful bass.

MP150

  • Positioning: An entry-level on-wall speaker designed for compact spaces.
  • Description: Offers low-compression tweeters and studio-monitor derived components to deliver clear sound in environments with limited space. Compared to higher series like the 300, M, and 950, it sacrifices advanced features and power for simplicity and affordability.

S300

  • Positioning: A compact, full-range speaker aimed at delivering reference home cinema sound.
  • Description: Uses driver mounting with isolated tweeter and woofer brackets to reduce cabinet coloration and maintain clarity. When compared with the S300T, M70, and MP950, it presents a straightforward design focused on purity of sound rather than the enhanced surround or advanced performance found in the higher series.

S300T

  • Positioning: A specialized tripole speaker optimized for immersive and precisely positioned rear sound.
  • Description: Integrates isolated side chambers with additional drivers to boost surround imaging and deliver a more enveloping sound field than the standard S300.

Expand Details

Product Strengths

  • Wide soundstage with evident front-to-back depth
  • Clear and detailed midrange response with good separation of instruments such as guitars and pianos
  • Balanced low-end response allowing for clearer definitions in bass notes
  • Precise time alignment contributes to accuracy, focus, and a uniform dispersion pattern
  • Detailed and airy top-end combined with a reach-out-and-touch-it three-dimensional width and imaging in the midrange

Product Considerations

  • Not an inexpensive monitor
  • At 41kg, it is also very heavy
  • At the large end of the nearfield monitoring spectrum—it's a midfield, really
  • Lacks DSP (Digital Signal Processing) found in many modern monitors, relying on traditional electro-acoustic design

Comparisons (according to reviewers)

  • Vs ATC SCM25A: Maintains a more balanced low-end response, while ATC SCM25A exhibited a slight bump in the lower mids

Takeaway: The Amphion One25A is an accurate and revealing mix tool with a perfect tonal balance, making it a good investment for professional use. Its low-end provides an utterly secure foundation for everything above, and it retains its dimension and punch at normal, moderate listening levels.

Reviews

As with any PMC loudspeaker, thanks to its super-consistent dispersion and tonal balance, the PMC8-2 may be simply and seamlessly combined with smaller PMC speakers to create larger multi-channel or immersive systems. The twin bass drivers are partnered with the same PMC55 mid-range tweeter, DSP system and four channels of 400W Class-D amplification used in the PMC6-2. Again, the speaker is configurable directly via the rear panel or using the browser-based SoundAlign™ software from a computer or tablet.

Together with the precisely tuned ATL™ cabinet and hexagonal Laminair™ vents, the PMC8-2 delivers phenomenal performance that approaches that of our Main reference monitors, with smooth and consistent bass response down to 25Hz, a revealing mid-range and wide, stable sound-staging. As with the rest of the range, the PMC8-2's superb definition, fidelity, dynamics and bass accuracy allow mix decisions to be made quickly with complete confidence, and with no listening fatigue even after long sessions.

PMC8-2s can be upgraded through the addition of a PMC8-2 SUB to create an XBD system, enhancing the system's bass headroom by 6dB. Dedicated short and taller floor-stands are available for the PMC8-2 and PMC8-2 XBD systems which position them on the ideal listening axis.

"Active 3-way nearfield reference monitor with ATL™ bass loading Frequency response: 25Hz - 25kHz (- 3dB @1m full space, on-axis) Max. cont. SPL: 113dB @1m (half space value calculated as +3dB from full space measurement. Unweighted input, 20-20kHz Pink Noise (IEC) with 12dB CF for 2 hours AES2-1984 duration) State-of-the-art Class-D amplifiers: HF 400W, MF 400W, LF 2x 400W Analogue / AES3 digital input (16/24-bit, 18 -192kHz sample rate) Digital 'through' output (AES3 24-bit 96kHz SoundAlign™ network control interface for single or group EQ & settings Sophisticated DSP crossover, driver protection, EQ, and delay/polarity options PMC8-2 + PMC8-2 SUB creates PMC8-2 XBD, with up to 6dB of additional headroom Optional dedicated floor stands for PMC8-2 (40") and PMC8-2 XBD (19")"

Our Summary

Product Strengths

  • Extremely clear sound, making them better for mixing and mastering than many other monitors
  • Sound like main monitors, offering a large sound footprint not typically found in near-field or mid-field monitors
  • Wide bandwidth accuracy and dependability at any volume level
  • Midrange performance is particularly notable for realistic, unhyped accuracy, especially on naturally recorded human voices
  • Bass performance combines extended bandwidth with great dynamic, pitch, and temporal accuracy

Product Considerations

  • Require a significant break-in period
  • To get the most out of them, an interface that can connect via AES is needed, as the conversion when using analog is not as transparent
  • Correct placement is crucial; at least four and a half feet of distance is needed between the listener and the monitor to be able to get all of the sound that it's trying to give
  • SoundAlign software, while useful for EQ adjustments, may introduce unwanted digital artifacts to the sound
  • Expensive, these monitors are at the higher end of this sector and share that space with some well-respected designs

Comparisons (according to reviewers)

  • Vs ATC SCM25a: The reviewer finds an absence of 'not hearing the box' evident in the 6-2 compared to the ATCs
  • Vs Neumann KH310s: The 6-2s outperform them in every respect, sounding much better, with other monitors sounding colored by comparison
  • Vs ATC 150s: The reviewer prefers these PMC6-2s over the ATC 150s

Takeaway: The PMC6-2 is a high-performance studio monitor that delivers exceptional clarity and detail. For those seeking accurate and dependable sound at all volumes, these monitors are worth consideration.

A brand new and innovative midrange driver entirely developed and manufactured in-house brings the A25-M even closer to absolute perfection. Imagine hearing sound as naturally as in real life. The speakers disappear, you trust what you hear and let your ears work with total confidence. That's what you get with the A25-M!
Check Amazon
PSI Audio is a Swiss hifi brand that builds all their speakers and acoustic devices without using DSP, focusing instead on pure analog technology to deliver accurate sound reproduction. Their standout product is the AVAA C20, a revolutionary active bass trap that eliminates low-frequency noise by creating a "black hole" effect for resonant frequencies, requiring much less space than traditional acoustic treatments while being effective across diverse environments from recording studios to subway stations.
Expand Details

Our Summary

Product Strengths

  • All three of the A25 speaker drivers are designed and handmade in-house in Switzerland to ensure low distortion, high precision, and the finest quality control
  • Every A25 is sonically identical, meaning any two of the same model at any point in their production history will be a matched pair
  • The A25M offers higher SPL at lower distortion
  • Initial listening tests were very favorable, and the first things that stood out were the tight and controlled low end and super precise stereo imaging, leading to a huge sense of depth and space
  • Mixes translated incredibly well to other systems, and when using them for mastering, the bass end was spot on, and the highs were incredibly detailed but not at all hyped or fatiguing

Product Considerations

  • The A25Ms are very heavy, at 28.4kg each, and have the kind of proportions that make a one-person lift of such a weight risky
  • The size and weight of the A25Ms mean they probably will not be considered for nearfield duties by the majority of potential users
  • The overall tonal balance is a little prominent in the upper-mid band, and this sometimes adds a slight edge to some mix elements
  • If considering a move to mid-field monitoring, room acoustics should probably be considered at the same time
  • Enclosure color is an acquired taste

Comparisons (according to reviewers)

  • Vs ATC SCM45s, the ATCs just had that extra tiny level of detail in the mids—it comes down to personal choice

Takeaway: The A25M is genuinely revealing monitors that can provide great insight into the components of a mix and how they fit together. These are spectacular monitors with a tight, controlled low end and super precise stereo imaging, making them an excellent mid-field monitor for mixing and mastering.
