Burson Audio's Stellar Headphone Amplifiers: A Deep Dive
Burson Audio, an Australian manufacturer known for its high-quality audio equipment, has recently unveiled its latest addition to the Stellar lineup: the Soloist Stellar and Conductor Stellar. These desktop headphone amplifiers are designed to cater to audiophiles seeking exceptional sound quality and versatility. In this article, we'll delve into the features and specifications of these amplifiers, exploring why they might be a game-changer for audio enthusiasts.
The Soloist Stellar: Pure Powerhouse
The Soloist Stellar is a DAC-less amplifier, focusing solely on delivering pristine audio through its analogue inputs. It boasts a Class-A discrete circuitry design, utilizing four ON Semiconductor MJE15032 transistors per channel for exceptional performance. This configuration ensures a clean and powerful output, making it an ideal choice for driving high-impedance headphones.
One of the standout features is its versatility in output options. It offers balanced XLR, single-ended 6.35mm, and single-ended 3.5mm headphone outputs, ensuring compatibility with various headphones. Additionally, a dedicated IEM output stage further reduces the noise floor, making it perfect for high-sensitivity in-ear monitors. The pre-amplifier outputs, available in XLR and RCA, provide the flexibility to drive power amplifiers or powered loudspeakers, making it a versatile tool for audio enthusiasts.
The Soloist Stellar also incorporates independent channel-balance controls, allowing users to fine-tune the audio for each ear, addressing any potential asymmetry in the listening environment. This level of customization is a welcome addition, ensuring a truly personalized listening experience.
The Conductor Stellar: Digital Excellence
The Conductor Stellar takes the Stellar lineup to the next level by integrating digital source capability. It employs an ESS ES9039PRO DAC chip, capable of handling PCM up to 32-bit/768kHz and DSD up to DSD512. This level of digital precision ensures that the amplifier can reproduce a wide range of audio frequencies with remarkable accuracy.
Digital connectivity is further enhanced by a Qualcomm CSR8675 chip, enabling Bluetooth 5.0 support with LDAC, aptX HD, and AAC codecs. This feature opens up a world of wireless audio possibilities, allowing users to stream high-quality audio from their devices seamlessly. The Conductor Stellar also includes a microphone bypass input, catering to gaming headset users who desire a direct connection without interference.
Power, Size, and a Subwoofer Output
Both the Soloist and Conductor Stellar amplifiers deliver an impressive 5 watts balanced and 2.5 watts single-ended into 32 ohms via the standard headphone outputs. However, when utilizing the IEM output, the power drops to 500 milliwatts balanced and 250 milliwatts single-ended. Despite this slight reduction, the amplifiers still provide ample power for driving a wide range of headphones.
Interestingly, both units feature a mono subwoofer RCA output, an unexpected yet welcome addition. This output allows users to connect a subwoofer, enhancing the bass response and creating a more immersive audio experience. This feature is particularly useful for those seeking to create a comprehensive home theater setup.
Pricing and Availability
The Burson Audio Soloist Stellar is priced at €1600/US$1500, while the Conductor Stellar carries a price tag of €1900/US$1800. Standard Edition units are currently available, and upgraded versions are available for special order. The press release, however, does not disclose the details of these upgrades, leaving enthusiasts intrigued and eager to discover the enhancements.
Final Thoughts
Burson Audio's Stellar amplifiers, particularly the Soloist and Conductor Stellar, showcase the brand's commitment to innovation and audio excellence. With their powerful performance, versatile output options, and attention to detail, these amplifiers are sure to captivate audiophiles and music enthusiasts alike. While the pricing may be considered a significant investment, the quality and features offered make it a compelling choice for those seeking an exceptional listening experience.
In my opinion, the Soloist Stellar's pure headphone amplifier approach is a refreshing take on the market, catering to audiophiles who prioritize simplicity and power. On the other hand, the Conductor Stellar's digital capabilities and Bluetooth support make it an attractive option for those seeking convenience without compromising on sound quality.
As an audio enthusiast, I find the inclusion of the mono subwoofer output particularly intriguing. It demonstrates Burson Audio's forward-thinking approach, catering to the evolving needs of modern audio setups. Overall, the Stellar amplifiers are a testament to Burson Audio's dedication to pushing the boundaries of audio technology, and I eagerly anticipate their impact on the industry.
