What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

Product Strengths

  • Excellent build quality and finish, engineered to last decades and pleasingly tactile
  • Delivers a tidy, serene, confident, calm, and clean sound, getting out of the way of the music
  • Great bass performance, reaching deep with control and poise
  • High continuous power output, and the actual peak power values are much higher than stated
  • Reveals a fully rendered, high-resolution sound that is tonally stronger than many solid state designs

Product Considerations

  • The M-700u power amp gives off a fair bit of heat when pushed hard, so it's a good idea to position it in a place with decent airflow
  • More sensitive to tone controls and more sensitive to the load, that is, to the loudspeakers used
  • Speaker cable terminals only accept spade connectors
  • Not quite as emotionally engaging as the best examples of the breed
  • From the box, the sound is thick, soft, and lacking clarity, but this improves markedly once properly warmed up

Comparisons (according to reviewers)

  • Vs Gamut D200i: The M-700u doesn't quite have the insight of the pricier Gamut D200i
  • Vs M-900u: The M-700u is closer to class AB sound, while the M-900u is closer to the previous Luxman's class A sound
  • Vs Luxman L-550AX: The direct comparison shows superiority of the C-700u and M-700u: the soundstage explodes laterally and in depth, microdynamics are supercharged, and artists regain their passion

Takeaway: The M-700u is a great power amplifier for anyone looking for high-end sound. Its refined sound, world-class build, and impressive power make it a very attractive proposition for music lovers.

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.

Product Strengths

  • More bass, richness, and musicality
  • An easiness, very inviting, and musical.
  • It never gets fatiguing.
  • The midrange was clean, uncolored, and detailed.
  • The highs were also clean, with no emphasis or sibilance on the sound of cymbals.

Product Considerations

  • Everything might have the same flavor, the same type of presentation—not allowing listeners to differentiate between classic rock, pop, jazz, and blues.
  • It is not the king when it comes to bass control.
  • It isn't going to be the king when it comes to dynamics and huge soundstage.
  • Its intent isn't to impress with explosiveness, dynamics, or a "holy shit" factor.
  • It might sound a little bit bright here and there, depending on cable or power cord match.

Comparisons (according to reviewers)

  • Vs Parasound Halo JC 1+: Replacing it with the Parasounds endowed the lows with extra weight, while equaling the Japanese amplifier's clean midrange and highs.

Takeaway: The Luxman M-10X is a very inviting and musical amplifier that romances listeners with a sweet presentation that is never fatiguing. It is a good choice for listeners who want a relaxing listening experience.

Our Summary

Product Strengths

  • The amplifier has a harmonic richness and bloom to the sound that's seductive
  • Bass was tight, controlled, very extended with pitch definition and detailed
  • The amplifier's ability to resolve low level spatial cues is amazing—sound stage layering, image specificity, size and shape are outstanding

Product Considerations

  • It is only available in black

Comparisons (according to reviewers)

  • The JCM250s give a performance very similar to Cambridge Audio JC1 Plus
  • The JCM250 is a bit warmer than the Cambridge Audio Edge M, and includes controls to set bias and gain
  • With the JCM250 monoblocks having a separate power supply for each channel, it has lower noise compared to the Cambridge Audio JC5
