By integrating state-of-the-art circuitry and meticulous craftsmanship, the new version not only delivers exceptional sound quality but also has remarkable aesthetics.
Technical highlights
The PCB design of the Burson V7 is meticulously crafted with up to 8 layers, strategically dividing the signal path, grounding, and shielding into separate layers. Despite the higher cost associated with this approach, it is considered the optimal method for designing analog amp circuits. Consequently, the Burson V7 op-amp not only offers a more compact and practical solution but also a shorter, optimized signal path. Moreover, its enhanced design ensures exceptional protection against airborne interference.
The V7 has been specifically designed to function flawlessly even under high temperatures. To ensure this, it is furnished with an innovative high-density aluminum shell. This shell efficiently disperses heat from every layer of the PCB into the surrounding air, while simultaneously providing protection to the delicate components housed within. With its practical and elegant design, the V7 is capable of accommodating a higher idling current, thereby elevating the audio quality and enhancing overall stability.
Burson Audio utilizes premium components that are meticulously calibrated and fine-tuned in a controlled environment to replicate real-world conditions. The Burson V7 op-amp is equipped with reverse voltage protection and is backed by a lifetime warranty.
Aesthetics and build quality
The op-amp is typically concealed within the audio device’s chassis, prioritizing functionality over aesthetics. Nevertheless, the Burson V7 op-amp stands out with its exquisite appearance and impeccable design. Despite the presence of dust, I would willingly showcase the chassis without its lid due to the op-amp’s stunning high-density aluminum shell. Not only does it efficiently dissipate heat, but it also has an appealing aesthetic and exceptional craftsmanship.
Two sonic flavors
The Burson V7 op-amp comes in two variations: the Vivid and the Classic. The V7 Vivid is renowned for its dynamic performance, crystal-clear sound, and precise accuracy, making it the perfect option for recording engineers who prioritize utmost precision. It is especially recommended for the initial output stages of DACs (Digital-to-Analog Converters), where transparency is highly appreciated.
The V7 Classic features a revamped output stage that tackles the shortcomings of its forerunner, the V6 Classic. With this enhancement, the V7 Classic achieves the same ultra-low noise level as the V7 Vivid, all while preserving the cherished intimate vocals and dazzling highs that V6 Classic enthusiasts adore. Moreover, it delivers enhanced dynamics and precision in the lower frequencies, striking a perfect equilibrium between enjoyment and gravitas.
Compatibility
The Burson V7’s compact dimensions (15mm x 13mm x 19mm) make it versatile for a wide range of applications, fitting seamlessly from computer sound-cards to DACs and amplifiers, provided there is sufficient height clearance. In cases where vertical space is limited, the Burson Audio 35mm extension leads can be purchased to facilitate horizontal op-amp positioning.
Both the Vivid and Classic versions of the Burson V7 op-amps come in dual and single configurations to cater to various usage needs. It is crucial to accurately determine the type of op-amp you intend to replace before making a purchase. During installation, it is essential to ensure the correct positioning and orientation of the op-amp. The Burson Audio website offers tutorial videos and manuals to assist in identifying and installing the op-amps. The process is simpler than it may seem, especially if your audio device is designed for easy op-amp rolling.
Working temperature
The V7 Vivid op-amps operate at elevated temperatures compared to the stock IC op-amps, resulting in an increase in the temperature of your audio device’s chassis. The extent of this temperature rise is contingent upon the number of V7 op-amps employed and the heat dissipation capabilities of the chassis. Fortunately, the Playmate 2 incorporates a chassis that functions as a substantial heat sink, resulting in only a slight increase in temperature that does not warrant significant concern.
Associated gear
Burson provided a set of dual and single V7 Vivid op-amps to upgrade the op-amps in the Burson Audio Playmate 2. During the evaluation, the stock power adapter of the Playmate 2 was swapped out for the Burson Super Charger. I used the same headphones as in the original Burson Playmate 2.
Moreover, I took the chance to try out the V7 Vivid in the Aune X8 XVIII DAC, which features a single removable op-amp. Unfortunately, the op-amp socket is inconveniently located at the bottom of the chassis, requiring the device to be placed upside down or sideways to accommodate the V7.
Listening impressions with the V7 Vivid
Caution: The listening experiences mentioned are specific to the V7 Vivid op-amps and do not pertain to the V7 Classic op-amps, as they are expected to have a distinct sound compared to the Vivid ones. You can find the V7 Classic op-amp review here.
Those familiar with the Burson Playmate 2, either as owners or readers of my review, are aware of its impressive sound capabilities. This device seamlessly blends exceptional musicality and analog timbre with competitive technical features. However, it is worth noting that the technical aspects are not class-leading, there is room for improvement in terms of transparency and clarity. Additionally, the noise floor may be slightly higher than desired when using sensitive earphones.
Following the replacement of the stock op-amps with the Burson V7 Vivid, a significant change was noted in the background noise levels. My belief was that IC op-amps are superior in noise performance compared to discrete components, however, this assumption was proven wrong. Interestingly, the Playmate 2 experienced a decrease in noise and a quieter sound output even with sensitive earphones like the FiiO FX15. Hence, there is no need to be concerned about the Burson V7 Vivid’s discrete circuitry as it does not introduce any unwanted noise and might even reduce the internal noise of your device.
