The Anniversary 10 (A10) is a culmination of all the experience that we have gathered over the last 10 years of designing and building HiFi speakers. Over the last decade, we have produced and sold thousands of speakers to happy HiFi enthusiasts from all around the world. Listening to feedback from our customers, learning from the best and adding our own flavor to the mix, has created extremely popular and critically acclaimed speakers, and now, this has evolved into our best sounding speaker yet. The A10 is something we are truly proud of, both in terms of sound, look and production values. It is a true celebration of our passion for amazing high-end sound, great engineering and high value products.
Our Summary
Product Strengths
- Exceptional bass performance for its compact size, with bass that is fast, clear, and tight
- Multiple 'Master Tunings' offer customizable sound profiles, adapting to different room acoustics and user preferences
- A high-quality Purifi woofer and SB Acoustics tweeter contribute to clarity, detail, and low distortion
- A solid wood cabinet made in Denmark provides a luxurious look and feel
Product Considerations
- Bass output may diminish or be limited at high volumes to protect the drivers from damage
- A separate purchase of the Platin Stereo Hub may be required for full wireless functionality and room correction
- The 'Made in China' label applies to the electronics inside the cabinet
- While the A10 offers impressive bass, some may still prefer to add a subwoofer for a true full-range experience
Comparisons (according to reviewers)
- Vs Buchardt S400 Mark II, the A10 is more transparent with greater inner detail, clarity, and top-end extension—and deeper, tighter bass—while the S400 Mark II is more relaxed and forgiving with harsh recordings
- Vs Buchardt A500, the A10 has comparable performance, with possibly a crisper sound in some instances
Takeaway: The Buchardt Anniversary 10 is a compact yet powerful speaker that offers a customizable listening experience. Its impressive bass and versatile tuning options make it a great choice for those seeking a high-quality audio solution in a small to medium-sized room.

Our take on the brand

Our Summary
Product Strengths
- Delivers greater tightness and precision from the crossover point on down
- Delivers an extended high-frequency range, with greater detail and more openness without harshness
- Stereo imaging is amongst the best
- Has no sweet 'spot', which allows the engineer, producer, and client a fairly similar listening experience
- Has a smoothly extended bass response that reveals what is really going on in that elusive bottom octave
Product Considerations
- The BM-15As may be overkill for a smaller mixing environment and better suited for larger rooms
- High end is as clean and accurate as the BM-12s, but the mids were a little lacking
- While they have a slightly forward characteristic, it doesn't get in the way of accurate monitoring
Comparisons (according to reviewers)
- Vs Dynaudio BM-12 MK3s—BM-15A has more bass extension and pure raw SPL power
- Vs Dynaudio BM-12 MK3s—BM-12 MK3s have more detail in the mid-range
- Vs Dynaudio BM-12 MK3s—BM-15A are far louder and put out substantially larger amount of energy in the bass and subs
- Vs Genelec, Focal, Neumann, and Event—the Dynaudio BM series are in the same class as these monitors
Takeaway: The BM15A is a speaker that gives great stereo imaging with a wide frequency range, and produces an accurate sound which is nice to listen to for long periods. Full-range monitoring in a smaller studio is possible with these speakers.

Our take on the brand

The LS3/5A was originally designed for listening places where space was limited, like mobile control rooms for television. The goal was a linear frequency response down to 100Hz with an excellent sound quality. Due to the closed type cabinet, the LS3/5A convinces with its clear and fast playback. As the speaker was designed to be used for studio applications, the midrange is extremely detailed and realistic. The sound stage and imaging of vocals and instruments is truly extraordinary. The LS3/5A works best in a near/mid-field listening distance between two and four meters away from the listener.
Our Summary
Product Strengths
- Delivers a clean, smooth, even, and detailed sound with pleasing subtlety and fine imaging
- Midrange is incredibly natural and fatigue-free with a slight warmth
- Exquisite build quality
- This version is reportedly one of the best-sounding LS3/5A variants on sale
Product Considerations
- Rolled-off bass response may need a subwoofer
- The sensitivity is very low, requiring more power from the amplifier
- Uppermost treble may lack the extension and air of ultra-modern speakers
- Some compression may be heard at high volumes
Comparisons (according to reviewers)
- Vs Sonos Faber Lumina 2: The Lumina 2 is even crisper up top, but leaner in the mid-bass
Takeaway: The Musical Fidelity LS3/5A is a classic speaker design reborn, offering a smooth, detailed, and natural sound that is particularly well-suited for small listening rooms and those who prioritize midrange richness. It can work well with a variety of music and amplifiers.

Our take on the brand

The Musical Fidelity LS5/9 is a two-way bass reflex speaker which was designed to reproduce sound at high levels to fulfil the complete range of music genres from classical to pop music. As the speaker was originally designed for recording studio applications, a low level of coloration was the goal to keep the musicitself untouched.
Our Summary
Product Strengths
- The Harwood LS 5/9 is a largely faithful replica of the legendary BBC monitor
- It has a pleasingly high efficiency of 88 dB
- It has a pleasingly linear progression of impedance, phase and EPDR, making it easy to drive with almost any amplifier
- High maximum level of 95 dB (continuous) and up to 105 decibels with music
- The sober and precisely tuned bass range enables the listener to push the LS 5/9 close to the rear wall without excessive booming bass
Product Considerations
- The replica tweeter is a good 2 decibels quieter than the original, which called the original BBC poll into question
- The LS 5/9 has a restraint in the mids (between 1.5–4 KHz), which is also reflected in the sound
- The LS 5/9 is not among the liveliest loudspeakers under the sun
- The tweeter adjustment requires re-soldering cables to the tweeter on the front
Comparisons (according to reviewers)
- The LS 5/9 plays lively compared to the LS 3/5a, which has virtually no dynamics at all
- The LS 5/9 is roughly on a par with the Dynaudio Heritage Special in terms of agility
- The Dynaudio Heritage Special produces much more and deeper bass from a considerably smaller cabinet
- The Dynaudio Heritage Special presented details in the mids and highs with even more grip, finesse, and airiness
- The LS 5/9 offers a very independent, highly cultivated form of reproduction that can be a charming alternative to equally expensive, modern designs
- The Harwood LS 5/9 sounds like an original Rogers model from the late 1980s
Takeaway: The Harwood LS 5/9 is a well-made replica that offers a musically natural tuning. It is electrically undemanding, making it suitable for any amplifier, and offers a charming alternative to modern designs.

- The built-in EQ and Sonarworks SoundID Reference integration allows users to tailor the sound to their specific room acoustics
- Wide, deep, highly detailed, and solidly centered soundfield
Product Considerations

- The A8H offers more DSP capabilities, and is less expensive than the HEDD Audio Type 20 MK2 or Neumann KH310
- It is halfway between the less expensive but less sophisticated Dynaudio LYD 48 and ADAM Audio's own S2V—which, although a 2 way, offers step up in terms of sophistication

Our take on the brand

Our Summary
Product Strengths
- Excellent balanced delivery with precise midrange
- Well-specified, easy-to-use EQ and room correction settings
- Good low-frequency extension given its compact size
- Produces a beautifully clean and well-defined sound, with no harshness in the highs and a real sense of spatial depth and stereo width

- There's no straightforward way to hook up the Core 5s to the Core Sub Compact if all connections are to remain analogue
Takeaway: The Core 5 is a compact, accurate, and high-quality studio monitor that delivers a balanced and detailed sound perfect for smaller studios or immersive setups. It is comfortable to work with for extended periods, making it a great choice for professional use.
