Is this the end of $2,000+ DACs? LAiV uDAC review

Summary

The video compares the Live Micro DAC with various high-end DACs, highlighting its features, sound quality, and value for money. The Micro DAC, priced just under $1,000, offers advanced capabilities like oversampling, non-oversampling modes, and multiple input options including I²S. It is shown to outperform similarly priced competitors, such as the Bifrost 2 and Topping Centurus, particularly when using a high-quality I²S input. While it can’t completely match the full-sized Live Harmony DAC, the Micro DAC offers a compact, upgradeable solution that delivers exceptional sound quality and flexibility for audiophiles seeking a high-performance, budget-friendly DAC.

Takeaways

• 🎧 The Live Micro DAC is a compact, versatile R2R DAC priced at $994, offering excellent value under $1,000.
• 🔌 It features multiple inputs: USB-B, coaxial, optical, and I²S, with XLR outputs only (no RCA).
• ⚡ The DAC has a discrete Class A output stage and supports both oversampling and non-oversampling modes, with oversampling generally preferred.
• 🎶 I²S input generally provides smoother and more detailed sound than USB, but the quality depends heavily on the source device.
• 📏 In comparisons, the Micro DAC is slightly smoother and more spacious than the Bifrost 2 and produces a more three-dimensional soundstage than the Jelli Labs J3 Pro.
• 💡 Sound differences among high-end DACs are subtle, often only noticeable in direct comparisons of tonal focus, soundstage width, and image clarity.
• 🔧 The Micro DAC can be paired with the Micro DDC to further optimize sound by converting any input to high-quality I²S, bringing it closer to the full-sized Harmony DAC.
• 🏗️ Live has designed a modular ecosystem, allowing users to start with the Micro DAC and gradually upgrade with additional components like the Micro DDC.
• -
• 📊 Even with premium I²S inputs or DDC optimization, the Harmony DAC remains slightly more transparent and detailed, though the Micro DAC achieves near-parity at a lower price and smaller size.
• -
• 💸 The Micro DAC is a strong all-around performer for under $1,000, offering flexibility, upgrade potential, and a balance of sound quality and features unmatched in its price range.

Q & A

What is the price of the Live Micro DAC and how does it compare to other DACs?

The Live Micro DAC is priced at $994, which makes it more affordable than the Topping Centurus. It offers a similar level of performance but at a lower price point, making it an attractive option for those seeking high-quality DACs under $1,000.

What are the key features of the Live Micro DAC?

The key features of the Live Micro DAC include its R2R DAC architecture, a discrete Class-A output stage, oversampling and non-oversampling modes, support for multiple input types (USB-B, Coaxial, Optical, and I²S), and a compact size with an external power supply.

How does the sound quality of the Live Micro DAC compare to other DACs?

The sound quality of the Micro DAC is very good, with a smooth and detailed presentation. Compared to other DACs like the Bifrost 2 and Jelli Labs J3 Pro, it is slightly smoother with a wider, more three-dimensional soundstage, but the differences are small and subjective, depending on user preferences and source devices.

Why does the reviewer prefer oversampling mode on the Live Micro DAC?

The reviewer prefers oversampling mode because it enhances focus, detail resolution, and creates a more balanced and natural sound. It delivers a better sense of imaging and depth compared to non-oversampling mode.

What role does input quality play in the sound performance of the Live Micro DAC?

Input quality is crucial for achieving the best sound performance. The reviewer notes that the I²S input sounds smoother and more detailed than the USB input. However, the source device connected to the DAC plays a significant role in determining the sound quality. A great source will always outperform a mediocre one, regardless of the DAC.

How does the Live Micro DAC compare to the Bifrost 2 in terms of soundstage?

The Micro DAC produces a slightly more three-dimensional sound and a wider soundstage compared to the Bifrost 2. While the differences are not huge, the Micro DAC's presentation is more holographic and focused.

What is the main limitation of the Live Micro DAC for tube amp users?

The main limitation of the Live Micro DAC is the lack of RCA outputs. Since it only offers XLR outputs, it is not compatible with systems that require RCA connections, such as tube amps.

How does the Jelli Labs J3 Pro compare to the Micro DAC?

The J3 Pro, when paired with upgraded Sparkos Labs Pro opamps, offers a crisper and more focused image in the soundstage, but the soundstage is flatter and more intimate compared to the Micro DAC. The Micro DAC, on the other hand, offers a larger, more spacious soundstage with better separation and a more lifelike presentation.

Can the Live Micro DAC be upgraded with additional components?

Yes, the Live Micro DAC can be upgraded with the Micro DDC, which converts USB input to high-quality I²S output. This upgrade improves the DAC's overall sound performance and brings it closer to the performance of the more expensive Harmony DAC.

How does the Live Micro DAC perform when compared to the Harmony DAC?

The Micro DAC, even when upgraded with the Micro DDC, does not fully match the Harmony DAC in terms of transparency, detail, and soundstage. However, the differences are minor, and the Micro DAC offers near-identical performance in a smaller form factor and at a much lower price.
