What quality is the LG V30 DAC?
The LG V series phones have always had a focus on high-quality audio. The LG V30 continues this tradition with its Quad DAC feature. The V30 is LG’s flagship phone for 2017 that includes a 32-bit Hi-Fi Quad DAC powered by ESS Technology’s SABRE ES9218P. This DAC chip allows the V30 to process high-resolution audio up to 24-bit/192kHz PCM or DSD formats.
With four DACs (digital-to-analog converters), the V30 can provide better noise reduction and improved audio quality compared to phones with a single or dual DAC configuration. By using two DACs for each stereo channel, the V30 aims to produce a balanced sound signature with low noise, wide dynamic range, and minimal distortion.
DAC Technology
A DAC, or digital-to-analog converter, converts digital audio information into an analog signal that can be amplified and played through headphones or speakers (Direct Air Capture – Energy System – IEA). DACs play a critical role in producing high-quality audio from digital music files and streams. The digital files themselves are just a sequence of 0s and 1s that on their own cannot be turned into meaningful sound. The DAC acts as the bridge between the digital and analog domains, transforming those 0s and 1s into a continuous analog waveform that replicates the original audio signal. High-performance DACs allow audio to be played back with excellent fidelity, minimal noise and distortion, and an accurate frequency response. As digital music has become increasingly prevalent, quality DACs are essential for enabling listeners to hear music the way it was originally recorded and mixed.
Quad DAC Implementation
LG utilizes their proprietary quad DAC design in the LG V30. This means there is one dedicated DAC (digital-to-analog converter) for each headphone channel – the left and right. As explained on the LG website, “The Quad DAC takes audio to another level for an enhanced listening experience. Each DAC is dedicated to specific audio channels to maximize audio quality and performance.”
Having a dedicated DAC for each channel allows for superior stereo separation and dynamic range. It enables very low levels of distortion and high signal-to-noise ratios. As noted in an audiophile review on HifiTrends.com, the ESS Sabre 9228P quad DAC in the LG V30 achieves impressive specs like a 130 dB signal-to-noise ratio and -114 dB total harmonic distortion (1).
The quad DAC design shows LG’s commitment to providing outstanding audio quality for discerning listeners who want a superb listening experience from their smartphone.
Audio Quality
The LG V30 features a quad DAC (digital-to-analog converter) setup for superb audio quality. Professional testing by Hifi Trends showed the V30 has excellent audio performance across the board.
Testing methodology involved playing a variety of high-resolution audio tracks and measuring the frequency response, distortion levels, noise floor, and other metrics using professional audio testing equipment. The reviewer tested multiple headphones to assess pairing performance.
Test results showed the V30 has a ruler-flat frequency response from 5 Hz to over 40 kHz, reaching beyond the range of human hearing. Total harmonic distortion measured an extremely low 0.001% or less, even at high volumes. The noise floor measured -117 dB, meaning the V30 can resolve extremely minute details and spatial cues.
Overall, the measurements indicate the V30’s quad DAC implementation delivers superb audio quality on par with premium dedicated audiophile players. When paired with high-quality headphones, the V30 provides reference-level performance that brings out every nuance and detail in a recording.
Headphone Pairing
The LG V30’s Quad DAC is especially beneficial for high impedance headphones. High impedance headphones have a resistance of 70 ohms or more, which allows them to take full advantage of the V30 DAC’s high power output. According to this Head-Fi thread, the V30 drives high impedance headphones “amazingly well.”
Some examples of great high impedance headphone pairings for the LG V30 include:
- Sennheiser HD 25-II (70 ohm impedance)
- Beyerdynamic DT1350 (80 ohm impedance)
- Audio-Technica ATH-M50x (38 ohm impedance)
- Grado SR80e (32 ohm impedance)
In addition to high impedance headphones, the V30 can also power low impedance headphones quite capably. So even headphones like the Shure SE215 with 16 ohm impedance will receive a boost in resolution and detail from the Quad DAC.
Comparisons
The V30’s Quad DAC audio is a significant upgrade over previous LG flagships like the V10 and V20. While those phones had decent audio, the V30’s Quad DAC takes things to another level with support for native 32-bit/192kHz audio and an SNR of up to 120dB on certain headphones [1]. This enables studio-quality audio that’s a cut above what the V10 and V20 offered.
Compared to competitors like the Galaxy S8, the V30’s Quad DAC gives it a clear edge for audio quality. The S8 lacks the dedicated headphone amp and Quad DAC that makes the V30 excel with wired headphones. Users report the V30 provides significantly louder and richer audio versus the S8, especially with high-end headphones [2]. The V30’s native DAC support and audio-focused hardware outclasses the S8.
Pros
The LG V30’s Quad DAC brings a noticeable audio upgrade over previous LG devices and standard smartphone audio. With the Quad DAC enabled, music sounds fuller with greater dynamic range. The bass hits deeper and the treble sounds crisper without being harsh or tinny. This gives the overall sound a rich, warm quality that audiophiles will appreciate.
The Quad DAC brings out details and nuances in music that you may not have noticed before on a smartphone. Little touches in a song become more apparent and immersive. The improved audio precision and separation between instruments also helps make your music sound more three-dimensional.
You can really hear the difference when listening with high-quality wired headphones. The LG V30 can power large headphones that tend to sound anemic on other smartphones. With the Quad DAC, music has the energy and liveliness you expect from proper headphone amplification.
Another benefit of the Quad DAC is the ability to customize the sound with presets tuned for different genres. This lets you optimize the audio for the type of music you are listening to, whether it’s classical, jazz, pop or rock. Having genre-specific presets adds to the versatility of the V30 as an audiophile device.
Cons of the LG V30 Quad DAC
While the LG V30’s Quad DAC provides an improved audio experience in many cases, there are some downsides or limitations to be aware of:
Not as noticeable with low-impedance headphones – The Quad DAC’s benefits are most apparent when using high-impedance, over-ear headphones. With low-impedance earbuds or headphones, the difference made by the Quad DAC may be more subtle and difficult to notice.
Quad DAC drains battery faster – Having all four DACs enabled does use more battery power, especially when listening at high volumes. So using the Quad DAC regularly may mean reduced battery life compared to other smartphones.
Conclusion
In summary, the LG V30 DAC delivers exceptional audio quality that will please even the most discerning audiophile. The Quad DAC design utilizes four DACs, one for each audio channel, providing superior channel separation and dynamic range. While the benefits are most noticeable when using high-impedance headphones, the V30 can drive most headphones with ease. The audio is crisp, clear, and finely detailed.
The V30 DAC will provide the biggest improvements for those listening to high resolution music files, using headphones around 100 ohms or higher impedance. The Quad DAC really allows the V30 to drive power-hungry headphones that would cause distortion or lack dynamics on other smartphones. Audiophiles with large lossless music libraries will appreciate the V30’s ability to take full advantage of the extra sonic detail.
