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.

McIntosh
MHA200 (75th Anniversary Edition)

/
8
Reviews
McIntosh is one of the most iconic amplifier brands in the world, recognizable for its signature blue LED displays and distinctive industrial design. With a legacy spanning decades, McIntosh is known to many, even outside the audiophile community, and is sold in both mass-market retailers and specialized hifi stores. Their amplifiers are characterized by a warm, tube-like sound that enriches the midrange and smooths out the overall tonal balance.

Expand Details

Product Strengths

  • A lovely, lush sounding performance that's hard to dislike and sounds smooth but far from lifeless, delivering high levels of detail in a cohesive and musical manner
  • A sympathetic performer, it prefers to play to its inferior partnering equipment's strengths than overly expose their weaknesses, as many hifi audio examples tend to do
  • It can cater for a wide range of headphones and connections and it is a benchmark product that's highly recommended
  • Zero musical flaws to report and is nearly perfect in execution
  • A stunning design to the eye and ear, it is overall a wonderful addition for the perfectionist who wants the very best performance at home or even in the studio

Product Considerations

  • The volume control operation lacks linearity, making it hard to make subtle changes in level
  • No input selector, so one should only connect one type at once
  • On some samples, the volume control is loose and wiggles in its chassis housing
  • The octal AC socket is a bit of an odd choice, considering most users might prefer IEC
  • The depth, snap and weight of the low end was dynamic and exciting on some recordings and less than stellar on others

Comparisons (according to reviewers)

  • Vs Musical Fidelity M1 HPA—the MHA200 has a lush warmness to the music that brings strings to life in a way that makes the M1 HPA sound somewhat sterile in comparison
  • Vs EAR Yoshino HP-4 reference—the MHA200 was a touch brighter than the reference, though only slightly

Takeaway: The MHA200 is an enjoyable product with a rich, balanced, and powerful sound, that's more forgiving than most rivals and can be enjoyed for years to come. This headphone amp is perfect for personal listening, design, and operation that will work its magic.

Kenzie OG
2659
2659
/
2
Reviews

The outstanding performance of the Kenzie headphone amplifier is made possible with custom wound ultra-high quality output transformers providing amazing frequency extension. The Kenzie does not use a voltage network, and has more than enough power to drive even the most difficult headphones. We chose 32 ohms and 600-ohm output taps to allow use with the widest variety of headphones; everything from Grado Labs, HiFiMan, Audeze, MrSpeakers, Sennheiser, and Beyerdynamic.

The Kenzie showcases the transformers on the chassis to frame in the unique 1626 single-ended tubes. We have included an Alps volume pot to allow attenuation and simplify the signal path. The Kenzie is one of the sweetest-sounding headphone amplifiers on the market. The 1626 is commonly referred to as the "Poor Man's 300B"; offering a similar level of warmth, texture, and soundstage depth. The 1626 is a WWII-era tube that was used as a transmitter tube in radar installations. The design is shy on pure output, but offers layers of texture and drive, and is paired with a massive choke and robust output transformers for ultra-quiet operation. As with all of our products, parts selection was crucial during this build and each chosen not for price, but for best quality and synergy.

Generation 2 of the Kenzie OG The close of 2021 has brought out more than 18 months of a global pandemic. During these challenging times, we at ampsandsound strengthened our development efforts resulting in new generation of our classic amps. 2022 adds the ability to chose 8/100 or 32/300 for output impedances when ordering. Though octal input tubes provide a romantic character that had defined the ampsandsound house sound, reminiscent of 1950s HiFi, the downside to this approach is a reduced noise floor and dwindling NOS options. With ampsandound moving to a 9pin front end, performance has been increased, NOS tube rolling has become nearly limitless, and yet we were able to enhance the sweetness and tone we are known for. The 9pin front end allows vastly increased options for tone rolling to find your balance and preference. With our front end's new development, we have improved our amps further, including both subtle and significant changes alike. Notable takeaways include increased power output, reduced noise floor across all our amps, increased bandwidth.

ampandsound specializes in high-end, handcrafted tube amplifiers made in the USA. Their low-wattage amps pair perfectly with high-efficiency speakers and headphones. The company is known for classic, minimalist designs and a focus on delivering natural sound.

Product Strengths

  • Unique 'tube character' enhances the sound in a positive way
  • Known for sweetness, euphony, and richness of tone
  • Enhances microdynamics, drawing attention to finer nuances of volume
  • Creates a more involved and textured soundstage
  • Is a completely neutral headphone amplifier, as long as the output impedance synergy is observed
  • Inputs and outputs are located on the back of the unit, which can be inconvenient

Product Considerations

  • Not suitable for very inefficient planar headphones like the HE6 or Audeze LCD-4
  • Not generally recommended for IEMs
  • Can be susceptible to interference from Wi-Fi signals or other electronic components
  • Depending on the headphone used, the environment, and the output being used, the unit may produce some noise floor

Takeaway: The Kenzie is a special tube amp that makes music sound sweet and detailed, improving the listening experience with many headphones, assuming the right setup is used. It's a good option for those who want to go beyond solid-state amps.
