Burson Audio V7 Classic op-amp

Last month Burson asked me if I wanted to test and review a set of Vivid V7 Pro’s unbiased in the Soloist 3XR GT. You can find that review here: Review Vivid V7. The Vivid V7 were without a doubt a better version of the Vivid V6. Now it is time to give the V7 Classics a test run.

Before I started testing, I let the Classic V7’s run in for a full of 48 hours.

Test equipment:
– Hifiman Arya Stealth V3 / Hifiman Arya Unveiled
– Burson Soloist 3XR GT + 5A Supercharger
– Eversolo A8 + upgraded LHY LPS
– DAC : Chord TT2 + Mscaler

This time I will make a comparison between the V7 Vivid and V7 Classic, ofcourse a brief comparison with the V6 is only logical.







The Burson Classic V7 op-amp presents itself as an elegant but quite an evolution over the V6.

From the very first notes, the Classic V7 delivers vocals with captivating realism, placing singers intimately within the sound space. Instruments possess a rich harmonic structure and acoustic music with remarkable authenticity and warmth. Its midrange is quite something special in the V7 Classics.

The Classic V7’s bass response is effortlessly smooth, possessing depth and warmth without compromising clarity (a lot of times the price for smoothness is the loss of clarity, not in case of the V7).

The sound is robust yet refined, the stage looses a little in stage compared to the Vivid V7 but a engaging soundstage nonetheless. The Classic V7 invites you to extended listening sessions without fatigue. Treble frequencies are articulate yet gentle, complementing rather than overshadowing the music.

If you are seeking for a sonic profile with an almost vintage analog warmth. The Burson Classic V7 stands out as an excellent choice, elevating the listening experience through a deeply musical and natural presentation.

I will let some songs pass by, trying to describe what I mean by all of this.


Sophie Milman is a captivating jazz vocalist known for her warm, in my opinion a slight smoky sounding voice. Her album ‘Take Love Easy’ beautifully showcases her talent, blending classic and modern jazz influences.

Listening to the track ‘That is love‘ accentuated the warm textures of her voice, highlighting the intimate nuances. Her voice sounded refined and the analog presentation complements the track perfectly, delivering an emotionally engaging and deeply immersive listening experience.



Nat King Cole one of my all time favourites! I love his velvety voice. His album Just One of Those Things beautifully combines sophisticated arrangements with Cole’s signature charm, Perfect for reviewing the Burson V7 Classics!

Have a look at the Burson Audio V7 Product Page

Burson Audio is a renowned Australian brand that makes award-winning digital-to-analog converters (DACs) and headphone amplifiers, including models such as the Playmate 3, Conductor, and Soloist.

What is less commonly known is that Burson Audio was among the pioneers in the audio industry to challenge the use of integrated circuit (IC) operational amplifiers in the audio signal path. This stance prompted them to engage in extensive research and development, ultimately leading to the creation of their own operational amplifiers, which are exclusively constructed from discrete components.

These are known as Burson Audio supreme sound op-amps, which have evolved through 20 years of dedicated innovation and have now reached their seventh generation.



Burson Audio V7 discrete op-amps

Burson Audio has introduced the V7 Pro series, marking the 7th generation of discrete op-amps and succeeding the highly regarded V6 series, after nearly twenty years of dedicated research and development. This latest generation features advanced circuitry and exceptional craftsmanship, delivering enhanced sound quality, improved heat dissipation, and striking visual appeal.

Technical stuff

The Burson V7 op-amp is constructed using up to 8 layers in its PCB design. This approach strategically separates signal path, grounding, and shielding into distinct layers. Although this method is more costly, it is considered the ideal approach for designing analog amp circuits. As a result, the Burson V7 op-amp is not only more compact and practical but also features a shorter signal path and better shielding against EMI.

The V7 is engineered to operate at high temperatures thus it is equipped with a new high-density aluminum shell. This shell effectively dissipates heat from each layer of the PCB into the air, while also safeguarding the sensitive components within. This design allows the V7 op-amp to work with a higher idling current.

Burson Audio uses only the finest audio components, which are matched and tuned in a temperature-controlled environment that simulates real-world operations.

The Burson V7 op-amp has reverse voltage protection and is covered by a lifetime warranty.

Classic or Vivid?

The Burson V7 op-amp is available in two versions, the Vivid and the Classic.

The V7 Vivid, standing out for its dynamism, clarity, and accuracy, is an ideal choice for applications that prioritize absolute precision and transparency.

On the other hand, the Burson V7 Classic features a completely redesigned output stage, addressing the limitations of its predecessor, the V6 Classic.

The V7 Classic now matches the ultra-low noise level of the V7 Vivid, while maintaining the beloved timbre that fans of V6 Classic appreciate. Additionally, it offers improved dynamics and accuracy in the lower frequencies, striking an ideal balance between enjoyment and seriousness.

Both the Vivid and Classic Burson V7 op-amps are available in dual and single variants, just like regular IC op-amps, to cover all usual electronic applications.



Non Audio stuff

An operational amplifier (op-amp) is typically an internal component of audio devices, where its visual appeal is often overlooked. However, the Burson V7 op-amp stands out with its exquisite design, making it a delight to behold. A transparent lid cover for the amplifier would enhance its visual appeal even further.

The outer casing is crafted from high-density aluminum, which not only provides efficient heat dissipation but also boasts an attractive appearance. The construction quality of the V7 op-amp surpasses that of the plastic V6 op-amp, reflecting superior craftsmanship.

How to install the op-amps

The compact dimensions of the Burson V7 Classic op-amp (15 x 13 x 19 mm) provide extensive compatibility with a range of audio devices, including computer sound cards, DACs, and amplifiers. It is important to ensure that there is sufficient height clearance for the V7 op-amp, as it is taller than standard IC op-amps. If the internal height of your device's chassis is limited, you can purchase Burson’s 35 mm flexible extension leads, which facilitate the horizontal installation of the op-amps.

Prior to purchasing the V7 op-amps, it is essential to consult the device’s manual or identify the type of stock op-amps currently in use. Pay close attention to whether the op-amps are dual or single type to ensure you order the correct variants.

Installation is straightforward, provided the op-amps are housed in DIP8 sockets. Carefully extract the stock op-amps, ideally using op-amp removal tweezers, and then install the Burson Audio op-amps, ensuring the correct orientation is maintained. If you are uncertain about the process, tutorial videos are available on Burson’s Audio website for guidance.

Burson Audio discrete op-amps operate at significantly higher temperatures than IC op-amps and produce more heat, so it is crucial to ensure that the device is adequately ventilated.



Associated gear

This review focuses specifically on the V7 Classic op-amps. For insights on the V7 Vivid op-amps, please refer to my other review.

The Violectric V380² is a premium DAC and headphone amplifier combination that is widely recognized as a standard in the audiophile community.

The balanced headphone amplifier features four distinct power amplifiers, one for each phase. Each of these power amplifiers is powered by a NE5534 op-amp at the input stage, which is socketed for easy replacement. In this instance, the original four op-amps have been substituted with Burson V7 Classic op-amps.

For this evaluation, I utilized the Hifiman Susvara and HE1000 Stealth headphones, both known for their exceptional transparency, paired with Lavricables pure silver cables.

Audio stuff

Switching back and forth between the stock IC and the Burson V7 Classic op-amps to do an A/B comparison is quite a complex task, which led me to limit my playlist to a select few favorite tracks while taking detailed listening notes. To streamline the process, I utilized the built-in DAC of the V380² in conjunction with the Volumio Rivo+ transport.

The NE5534 op-amp is a popular choice in audio applications due to its remarkably low noise levels, impressive output drive capability, high unity-gain bandwidth, minimal distortion, and rapid slew rate.

Replacing the NE5534 with the Burson V7 Classic op-amps did not adversely impact the technical performance of the V380² in any way. The sound quality remained entirely transparent and pristine, maintaining the exceptional fidelity and precision characteristic of the Violectric V380², so there is no need for concern regarding any compromise in the amplifier's technical capabilities.

The introduction of the Burson V7 Classic op-amps altered the sound signature to a subtly different direction while still achieving the same high standard. It can be likened to adjusting the seasoning in a beloved dish; the overall flavor remains delightful, but the aftertaste may vary slightly.

In the already controlled sounding amplifier, the discrete op-amps contributed by slightly softening the overall presentation, introducing a sense of ease while maintaining control. The bass becomes more flexible and engaging, yet retains its tightness and precision, while the treble exhibits a more refined character without sacrificing extension and clarity. Although there may be a slight reduction in dynamic impact and attack, the bass benefits from increased weight and fullness.

The mid-range remains clear and well-defined, while also becoming richer and more harmonically diverse. The V380² is an amplifier known for its remarkably natural timbre, and the Burson V7 Classic op-amps enhance its analog and organic qualities without negatively affecting the sound.

The internal DAC of the V380² can occasionally exhibit a sharp and sterile sound profile; however, this is significantly mitigated when using the V7 Classic op-amps, which effectively minimize digital glare. While the transient response may not match the speed of the NE5534, the treble frequencies transition in a more natural and convincing manner.

Replacing the stock IC with the V7 Classic op-amps is akin to introducing a tube buffer stage prior to the power amplifiers. The Burson V7 Classic op-amps tend to introduce harmonics that enhance the realism and lifelike quality of the timbre, all while maintaining the amplifier's technical performance and linearity. Additionally, the soundstage acquires a tube-like quality, enhancing holographic layering without compromising imaging accuracy.



Further notes

It is important to clarify that the differences we are discussing are not drastic but rather subtle enhancements in sound quality that many users may find appealing compared to the original sonic profile of the audio device in question.

Nonetheless, it is quite possible that some individuals may not appreciate the alterations introduced by the Burson V7 Classic op-amps and may choose to retain the stock configuration.

Additionally, it should be noted that all previous listening observations pertain specifically to the Violectric V380² DAC/amp utilized in this review, and there is no assurance that all audio devices will respond similarly.

Comparison with the Burson Audio V7 Vivid op-amps

The V7 Classic op-amps offer a slightly different sound profile compared to the V7 Vivid op-amps, trading some degree of transparency and precision for a richer timbral quality. While the distinctions are subtle, the V7 Classic op-amps tend to impart a more organic and analog-like essence to the sound, in contrast to the Vivid models. The choice between the two ultimately hinges on whether you prioritize optimal solid-state fidelity and clarity or prefer to introduce a hint of tube-like warmth to your music.

Ultimately, I found both the V7 Classic and Vivid op-amps to provide a superior listening experience compared to the stock IC op-amps, which are now relegated to a distant shelf.

Conclusion

Exploring new sonic avenues and enhancing your favorite music can be achieved through the use of tubes. However, if you do not possess tube equipment or prefer to avoid tubes altogether, there is an alternative. If you are fortunate enough to have solid-state audio gear with socketed op-amps, you can delve into the hobby of op-amp rolling. While it may not provide the same level of impact as tube rolling, it can be just as engaging.

You can experiment with various IC op-amps, but it is unlikely that any will match the sound quality of Burson Audio's discrete op-amps. Among their two options, the Classic and the Vivid, the Vivid is technically impressive, yet the Classic is ideal for those seeking to enrich harmonic diversity and enhance melodic lines without significant compromises in performance. Don't hesitate to give them a try; you may find that they elevate your favorite music to new heights.
