This review dives into the Fosi Audio Q6 DAC and V3 amplifier, a compact and surprisingly powerful mini hi-fi system perfect for desktop setups. We explore the individual components, assessing their performance, build quality, and ease of use. The V3 amplifier, with its minimalist design and swappable op-amps, promises high-fidelity audio reproduction, while the Q6 DAC aims to elevate the listening experience with its high-quality AK4493SEQ DAC chip. We'll examine their individual strengths and how they synergistically enhance each other, delivering a sound quality that far exceeds their modest price point.Our testing included pairing the Fosi Audio system with the Aillic S10 Plus music streamer, allowing us to evaluate their performance with various audio sources. We'll delve into the sonic characteristics of both components—examining their frequency response, clarity, and overall listening experience. We also consider the limitations of the system, such as the lack of Bluetooth connectivity on the Q6, and compare it to Fosi Audio's other offerings to help determine if this mini hi-fi setup is the right choice for your needs and budget.

Fosi Audio V3 Amplifier: Design and Build
The Fosi Audio V3 amplifier boasts a compact design, ideal for desktop setups. While not as small as the BT20A, it's significantly smaller than the ZA3. Its simplicity is a key feature; a single knob serves as both the on/off switch and volume control. This minimalist approach keeps the focus on audio quality.
The rear panel features RCA connectors and speaker inputs, simple yet effective. Internally, the V3 utilizes high-quality components, including German Wima output capacitors and a selection of Japanese capacitors and inductors for superior sound reproduction.
A notable feature is the inclusion of swappable op-amps, allowing users to fine-tune the amplifier's sound signature to their preference. The TPA3255 chipset provides ample power for desktop use, though an upgrade to the power supply can increase the maximum output significantly.
Fosi Audio V3 Amplifier: Performance and Sound Quality
The V3 amplifier delivers a remarkably neutral sound across the entire frequency spectrum. There's no noticeable bias towards bass, treble, or mids, providing a well-balanced audio experience. Testing involved using an Aillic S10 Plus music streamer and Spotify, showing the V3's capability to handle a range of sources.
Even with the S10 Plus's basic DAC, the V3 reproduced a complete tonal range with no overheating and controlled power delivery. Its performance is impressive, especially considering its price point and compact design. The V3 handles power well and avoids distortion at high volumes.
While lacking bench testing data, reviews from websites like audiociencereview.com show it performs very well, falling in the “very good” category among similar products. This confirms the subjective listening experience of a balanced and detailed sound reproduction.
Fosi Audio Q6 DAC: Features and Build
The Fosi Audio Q6 DAC matches the V3's compact footprint. It features a simple interface: an on/off switch and a single knob for selecting between USB, optical, and coaxial inputs. Its design prioritizes ease of use without compromising functionality. The compact design and simple controls make it visually appealing and easy to use.
The rear panel provides optical and coaxial inputs, RCA outputs, and a subwoofer output, providing versatility in connectivity options. The internal build quality is excellent, featuring high-quality components like the AK4493SEQ DAC chip and an NE5532DR amp chip (potentially swappable).
The Q6 lacks volume control and a remote, aligning with its minimalist design philosophy. Despite not being technically a preamplifier, the op-amp integration improves the overall signal level, boosting the audio output when paired with an amplifier.
Fosi Audio Q6 DAC: Performance and Combined System Review
Paired with the V3 amplifier and Aillic S10 Plus streamer, the Q6 DAC delivers a significant improvement in sound quality over the streamer's built-in DAC. This enhancement is noticeable in both volume and overall audio clarity. The enhanced audio detail, cleaner sound, and improved volume levels make a worthwhile improvement to the overall listening experience.
While not strictly necessary, the Q6 complements the V3 perfectly, creating a superior desktop audio setup. The combination provides a high-quality listening experience for its compact footprint. The combined setup of the V3 and Q6 DAC offers excellent sound and functionality.
The Q6's connectivity is sufficient for most desktop setups, although it lacks Bluetooth and HDMI ARC. However, given its affordable price, the added sound quality is a significant benefit.
Conclusion: Are these products worth buying?
The Fosi Audio V3 amplifier is a highly recommended choice for those seeking a compact, high-quality desktop amplifier. Its neutral sound profile, durable build, and swappable op-amps make it a versatile option. The Q6 DAC, while not essential, is a worthwhile investment if you desire enhanced sound quality in a small form factor.
Paired together, the V3 and Q6 create an excellent mini hi-fi system, ideal for desktop setups. The improved sound and functionality offered by the Q6 DAC significantly upgrade the listening experience of the overall setup. This combination offers great value for its price.
If budget and space allow, however, the more feature-rich ZA3 and ZD3 amplifiers from Fosi Audio offer superior connectivity. Ultimately, the best choice depends on individual needs and priorities.
