Analysis Plus Solo Crystal Oval XLR Interconnect Review

The Analysis Plus Solo Crystal Oval XLR is a balanced analog interconnect from the American cable specialist Analysis Plus. It sits in the mid-to-upper range of their interconnect lineup and uses the company’s signature technologies: continuous-cast single-crystal copper conductors and the patented hollow-oval geometry. Hand-built in Michigan, it has earned a strong reputation among reviewers and owners for delivering high performance at a more approachable price than many competing high-end cables.

Design and Construction

The Solo Crystal Oval employs continuous-cast (or “solo crystal”) copper. In conventional copper, the signal must cross numerous grain boundaries; continuous casting creates long, single-crystal conductors that minimize those boundaries. The conductors are braided into Analysis Plus’s hollow-oval geometry, which the company claims reduces skin effect and proximity effect while promoting more even current distribution compared with traditional round conductors.

The cable features multi-layer shielding for noise rejection and a low-loss dielectric. XLR versions are typically terminated with high-quality connectors such as Abbatron (with beryllium-copper sockets and tellurium-copper pins) or Neutrik. The outer jacket is often a distinctive braided design with purple accents. Construction quality is solid, and the cables are flexible enough for practical system use.

Sound Quality

Reviewers consistently describe the Solo Crystal Oval as clear, detailed, and musically engaging without sounding thin or analytical.

• Clarity and resolution: The cable is frequently praised for transparency and detail retrieval. It presents a high-resolution view of the recording while avoiding harshness or edge.
• Midrange: One of its strongest attributes. Reviewers note a palpable, fleshy, and natural midrange that gives voices and instruments body and presence—the opposite of thin or bleached.
• Bass: Rich, controlled, and well-defined, with good weight and extension.
• Treble and overall balance: Smooth and extended, with a slightly relaxed or “luxurious” character rather than an ultra-crisp or airy presentation. Some listeners find it less open or agile than far more expensive references (such as certain Transparent models), but it remains detailed and non-fatiguing.
• Soundstage and dynamics: Capable of a coherent, well-organized soundstage with good depth. Dynamics are lively and the cable preserves the timing and energy of the music.

Overall character is neutral-to-slightly rich, with an emphasis on musicality and body rather than clinical precision. It tends to reveal the quality of the source material—better recordings sound better—while remaining enjoyable across a wide range of music.

Pros

• Clear, detailed, and transparent sound
• Full, natural midrange with good body
• Solid bass control and weight
• Effective noise rejection from the design and shielding
• Strong value relative to higher-priced competitors
• Well-made, with quality connectors
• Hand-built in the USA

Cons

• Not the most open, airy, or ultra-refined cable in absolute terms (higher-priced options can exceed it in those areas)
• Some systems may prefer a brighter or more “etched” presentation
• Premium pricing compared with entry-level interconnects (though competitive within the high-end category)

Verdict

The Analysis Plus Solo Crystal Oval XLR is a well-engineered balanced interconnect that delivers clarity, midrange substance, and musical engagement without the extreme cost of many flagship cables. Its continuous-cast copper and hollow-oval geometry contribute to a transparent yet full-bodied presentation that many listeners find highly satisfying.

It is particularly well-suited to systems that benefit from added midrange body and controlled detail, and it pairs effectively with a wide range of components. While it may not match the absolute refinement or air of cables costing several times more, it offers a large portion of high-end performance at a more realistic price. Strongly recommended for listeners seeking a clear, natural, and involving interconnect that lets the music through without imposing a strong editorial signature.
