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

  • The 'HFM' button noticeably improves HIFIMAN headphones, opening them up and creating space for instruments to breathe
  • The XBass feature adds a bass ramp, increasing subbass more than a midbass bump, which is useful for headphones/IEMs with a flat or rolled-off low end
  • The option of XBass is bound to please plenty of people
  • The 3D function effectively widens the soundstage on the HD6XX and fixes the '3-blob' effect, improving imaging
  • Solid single ended and balanced connections give clean power

Product Considerations

  • Enabling both the 'HD 6XX' function and the '3D' effect makes the 5-6kHz peak too noticeable, potentially causing fatigue
  • The HD6XX button also adds quite a bit of treble energy at around five to 6K hertz, which may cause a little bit too aggressive in that area
  • Channel imbalance can be present at the lowest settings

Comparisons (according to reviewers)

  • The Signature DAC may sound more analytical, but the difference may not be significant enough to justify the price increase for the HD 6XX
  • With the regular Zen CAN, one gets basically all the features of the Drop Signature Zen CAN, and one gets to retain the smooth quality of the HD6XX with the bass boost function
  • A hint of things being smoother compared to the Asgard 3
  • The adjustment one gets from the non-signature edition's 'XBass' function that doesn't boost 5-6khz as well is more pleasing to some

Takeaway:

The ZEN can be a good choice for those looking for a convenient way to adjust the sound of their headphones with the push of a button, especially for those who are not comfortable with EQ software. Overall, the ZEN product family offers a lot of versatility and great features.

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.

Reviews

The MX-HPA’s technical performance is stunning. Typically, distortion from 20 Hz to 40 kHz is less than 0.005%. Signal-to-noise ratio is better than 120dB (‘A’ weighted). Frequency response is ruler flat from 10 Hz to 20 kHz (-0.1dB). The MX-HPA is capable of a short-term peak of 10 watts (for one cycle) and has two gain positions: 18dB (8X) and 24dB (15X). Inputs are either balanced or single-ended. The MX-HPA will automatically convert single-ended inputs to balanced. The MX-HPA is genuinely fully balanced from beginning to end.

Musical Fidelity is known for its unique amplifier designs, particularly the A1 integrated amplifier that uses its top plate as a heatsink and features a distinctive current-mode phono stage. The brand stands out for its innovative dual-monoblock approach in integrated amplifiers, where separate power transformers and dedicated power supplies are housed in a single chassis, as seen in their M8xi and M6i models that deliver exceptional power output.

Expand Details

Our Summary

Product Strengths

  • Objectively an excellently performing amplifier with a discrete design and potentially lower noise floor than op-amp based designs

Product Considerations

  • The volume knob may have a scratchy feel
  • The halo feedback design may not make a significant difference in terms of measured behavior of headphones
  • Protection circuit may kick in and limit power at lower impedances
  • Preamp outputs cannot be switched off when using headphones

Comparisons (according to reviewers)

  • Vs Schiit Magni+, the Midgard offers better clarity and separation, especially when using the balanced output, but the tonal balance is similar
  • Vs Schiit Asgard 3, the Midgard is more neutral and clarity-focused, while the Asgard 3 is warmer and richer, with a better sense of soundstage depth
  • Vs Topping A30 Pro, the Midgard offers a resolution and finesse that the A30 Pro cannot reach—being more natural, open and fun
  • Vs Schiit Jotunheim 2, both are similar in terms of overall sound quality, but the Midgard stands out because its midrange is stuff from legends

Expand Details

Our Summary

Product Strengths

  • Enjoyable overall presentation with a punchy bassline, slightly euphonic midrange, and crystalline treble response
  • Expansive soundstage that allows the music to breathe and come to life
  • Enough power to drive most moderately hard-to-drive headphones, even those with higher impedance
  • Detailed and textured vocal range that is a touch more forward and warmer than clinically accurate
  • Tactile controls allow quicker access to changing any of the settings on the device

Product Considerations

  • Slight bright tilt, which may require careful pairing with other components
  • Bass is present, but slightly rolled off
  • Lacks a screen, which some users may find to be a downside
  • Balanced connection is present for convenience, as the amplifier itself is not a differential design—meaning it's single-ended by nature

Comparisons (according to reviewers)

  • SMSL SH-8s bass tends to be a touch more forward, SMSL SH-9 delivers a slightly tighter bass line
  • The SMSL SH-9 has a markedly more controlled treble response
  • Both have similar power output at 16Ω, but Topping A30 Pro maintains higher power at 32Ω
  • The SMSL SH-8s has a fuller instrument timbre, but Topping A30 Pro has a more euphonic vocal range
  • The SMSL SH-8s has much bigger headroom, and feels more spacious compared to the Geshelli Labs Archel 2.5 Pro
  • The SMSL SH-8s is clearly digging more details, and is also able to develop a wider soundstage with better separation and layering than the Topping L30

Takeaway: The SMSL SH-8s is a well-built amplifier that sounds promising. If the listener has darker sounding headphones or a darker source, the SMSL SH-8s might be worth checking out to open the sound a little bit.
