Unique Power Amp Design for Headphones
The Valencia is a groundbreaking headphone amplifier, designed as a dedicated power amp. Unlike typical headphone amps, it features a minimalist design with only a power switch and no gain or volume controls. This unique approach allows the Valencia to deliver a constant 15 watts per channel at 32 ohms, resulting in a powerful and pristine sound.

This sets it apart from traditional headphone amps that rely on adjusting gain and volume. The Valencia's raw power requires an external preamp or integrated amp to control the volume, which allows for greater flexibility and control over your audio setup.

This design philosophy speaks to a pure, powerful signal delivery without unnecessary processing. The result is a sound that's both impressive and transparent, allowing your headphones to shine.
Orchard Audio's Collaboration and Sound Quality
The collaboration between Z Reviews and Orchard Audio resulted in the Valencia, named after a type of peach. Orchard Audio, known for high-quality speaker amplifiers, brings its expertise to create this powerful headphone amp.

Z Reviews' involvement played a crucial role in influencing the amplifier's design and features. Their feedback helped ensure the Valencia would meet the needs of demanding headphone listeners, including the inclusion of a 4.4mm balanced adapter.

The result is an amplifier that delivers an exceptionally clean sound, exceeding expectations even with demanding headphones like the Z Reviews' flagship, Tungsten. The clean output is attributed to the high-quality components and minimalist design.
Power Amp Usage and Considerations
A crucial aspect of the Valencia is its nature as a power amplifier, unlike typical headphone amplifiers. This requires using a preamp or integrated amp to manage volume and potentially other signal processing. This adds complexity, but offers significant advantages.

Because of its powerful nature, the Valencia is incredibly revealing of any flaws or imperfections in the audio signal chain upstream of it. This is both a benefit and a potential drawback, depending on the quality of the rest of your equipment.
Users must carefully select their source components and cabling to fully utilize the Valencia's capabilities while avoiding noise or distortion. This makes it best suited for those who are comfortable with high-end audio systems and have well-matched components.
Specifications, Build Quality, and Accessories
The Valencia boasts 15 watts per channel at 32 ohms, with varying power output at different impedance levels. This impressive power output comes in a surprisingly compact and stylish chassis, made of sand-blasted steel and aluminum.

Every unit includes a 4-pin to 4.4mm balanced adapter cable, providing compatibility with a wider range of headphones. It's also bundled with a high-quality Monoprice Hospital cable.
The internal components are manufactured in Canada, emphasizing quality construction and performance. The amplifier's compact size belies its powerful performance and clean sound signature. The build quality is excellent.
Measurements and Performance
The Valencia undergoes rigorous testing with various headphone impedance levels, demonstrating exceptionally low total harmonic distortion (THD) and noise even at high power output. These results are impressive for a headphone amplifier.

The amplifier's transparency and minimal coloration allow the listener to experience the full potential of their headphones and source equipment. High-resolution measurements confirm its remarkable linearity and sound quality.
Its ability to drive even the most demanding headphones, such as the Tungsten, highlights its remarkable power and performance. The results showcase its capabilities in delivering a highly detailed and accurate sound.
Conclusion and Verdict
The Valencia is a unique and powerful headphone amplifier that represents a significant advancement in headphone amplification. Its minimalist design and powerful output deliver a clean, transparent sound that reveals the full potential of any headphone.

Despite requiring an external preamp to manage volume, the Valencia's superior sound quality and power make it a worthwhile investment for serious audiophiles. This amp isn't simply about volume; it is about incredibly pure and accurate signal delivery.
While it requires a sophisticated audio setup and careful consideration of impedance matching, the Valencia's ability to reveal the nuances of high-end headphones and source gear is remarkable. It's a must-have for audiophiles looking for exceptional sonic clarity and power.
