Product Strengths

• The Acapella Apollon's plasma tweeter produces extended, pure, and dynamic sound, and the speakers have good resolution
• Able to reproduce the subtleties of a recording with realistic reproduction of the dynamics of very low-level information
• Use a sealed bass alignment, meaning the distance from the back wall is not quite as critical as it would be with a ported speaker
• Efficient and work well with smallish tube amps

Product Considerations

• The Acapella Apollon speakers are large and probably require a dedicated listening room
• Heavy and require on-site assembly—the total shipping weight is 1,643 pounds
• Require a break-in period of 30 to 90 days
• One reviewer had initial issues with the tweeter malfunctioning, requiring tube replacements

Comparisons (according to reviewers)

• Vs Acapella Campanile: Look like bigger Campaniles with bigger cabinet and bigger horn, better crossover, better drivers, more expensive
• Vs Acapella Triolon: More resolution and integrated sound, but less dynamic in the mids
• Vs Marten Supremes: More open, dynamic, and musical, but ultimately has less resolution
• Vs Avalon Eidolons: Can go right up against the front wall unlike the Avalon Eidolons, which were further out in the room

Takeaway: The Acapella Apollon speakers are high-performing speakers able to reproduce subtle details, work with tube amps, and do not need a lot of space from the back wall. With the available space and budget, the Acapella Apollon could be a good choice.

Product Strengths

• Capable of creating a 'completely credible illusion' of live music, including solo artists, rock bands, or a symphony orchestra
• Listeners can perceive details in recordings, revealing elements that may have been previously unnoticed, such as the pressure and realism of a bass drum
• Thanks to its sensitivity of well over 100 decibels, it manages to trace the played content down to the finest detail, even at moderate volume levels
• Voices are projected with an incredibly natural sound
• The system's design eliminates the need for a separate bass horn acoustically coupling to the room
• Connectivity options

Product Considerations

• Limited listening time made it difficult to assess long-term satisfaction
• The Acapella Spharon is very heavy, with an estimated weight between 650 and 750 kilograms per side
• The system requires a large room (from 40 m²), and one installation occurred in a room that was 19.5 meters long x 13.7 wide and 6.4 high
• It can make any technical gadgetry within a recording instantly audible, potentially revealing unwanted artifacts

Comparisons (according to reviewers)

• Vs Acapella Poseydon: It plays in a more casual manner with almost unlimited dynamics than the Poseydon

Takeaway: The Acapella Spharon Excalibur is a state-of-the-art speaker system that offers a realistic and detailed audio performance. It allows the listener to experience music in a pleasurable way, bringing them closer to the original recording.

Product Strengths

• Three-way system with a quad of 15-inch woofers, the signature hyperspherical horn for the mid/highs and above 5kHz, and the firm's famous ion tweeter
• Large cone surface coupled to a special dual bass reflex system promised abysmal reach down to 16 Hertz
• The cabinets exploit a sandwich construction of Ply, MDF and acrylic plus secret insulators and adhesives

Product Considerations

• At 300kg each, Hyperion is immovable once installed on a sufficiently strong floor
• Requires weeks of lead time until final delivery and on-site setup

Takeaway: The Hyperion seems to create a persuasive live illusion. The speakers scale the music with care to conjure up a most persuasive experience.

Product Strengths

• Detailed, exciting, dynamic, and transparent sound
• Vanishingly low cabinet coloration, contributing to speed and detail
• Lung-emptying, bowel-clearing, demolition-grade bass
• Bass integrates well with the rest of the frequency range for an integrated musical performance
• Voices have breath and contour, yet the result always retains a minimum of warmth

Product Considerations

• Room acoustics should be a strong consideration, as the BC150 reveals room issues
• Needs a lot of quality electronics upstream
• Requires firm control and ample current capacity from the amplifier

Comparisons (according to reviewers)

• The BC150 sounds more like a Burmester B38 with greater abilities to scale

Takeaway: The Burmester BC150 is a high-precision audio instrument that is both musically communicative and musically analytical, offering a detailed and transparent listening experience. It offers clarity and purity of sound, and brings music to another level.

Product Strengths

• The M3 presents music with an unprecedented degree of individuality and specificity, without sacrificing tonality, texture, or body
• Remarkable level of resolution
• Astonishing transparency and is resolute
• Accurate tonality and represents timbre faithfully
• Exceptional high-frequency detail and speed due to a planar tweeter
• Accepts only banana terminations

Product Considerations

• The planar tweeter misses the very last measure of extension, shimmer, and effortlessness accomplished by the very best available today
• Low-frequency extension was limited to the high 20 Hz, low 30 Hz range

Comparisons (according to reviewers)

• Compared to Magico M9, the M3 has recalibrated the resolution yardstick by which all other loudspeakers must be measured and compared
• Compared to Von Schweikert Audio ULTRA 9s, the M3 has recalibrated the resolution yardstick by which all other loudspeakers must be measured and compared

Takeaway: The Børresen M3 loudspeakers boldly represent the realization of striking potential in audio and push known boundaries. People who choose the M3 will enjoy a specific level of playback that is unavailable from other loudspeakers.
