Product description Fosi Audio ZA3 2CH mono amplifier

Breathe new life into your audio setup with the versatile Fosi Audio ZA3 2CH Amplifier. This feature-packed amplifier caters to both traditional stereo listening and more advanced setups for audiophiles. The ZA3's defining characteristic is its dual-mode functionality. In stereo mode, it delivers robust power to drive two passive speakers for a clear and detailed listening experience. However, the magic lies in its ability to switch to mono mode. This unlocks two potential benefits: dedicating all its amplification power to a single speaker for a louder and more dynamic sound, or utilizing two ZA3 units in mono mode for improved stereo separation in a wider soundstage.

Product details

Fosi Audio ZA3 Balanced Stereo Amplifier 2CH Mono Amp

Beyond its versatile operation modes, the Fosi Audio ZA3 boasts high-performance digital amplification thanks to a well-regarded Texas Instruments TPA3255 chip. This translates to clean and clear audio reproduction, ensuring you can fully appreciate the nuances of your music or movies. Balanced XLR and RCA inputs provide flexible connectivity options for integrating the ZA3 into various audio setups, while the compact and stylish design ensures it complements any space. Whether you're seeking to enhance a traditional stereo setup or explore the possibilities of wider soundstages, the Fosi Audio ZA3 2CH Mono Amplifier is a compelling choice for discerning listeners.

Upgrade Options

For audiophiles looking to take their sound experience to the next level, the original Op Amps in the Fosi Audio ZA2 Amplifier can be replaced with the SparkoS SS3602 Dual Op Amp. These Op Amps enhance the sound signature by enhancing clarity, warmth, and a wider soundstage, resulting in a smoother and more dynamic audio performance making the V3 an even more versatile and powerful choice for your audio needs.

Kam gut verpackt und schnell an. Alles wie beschrieben.

Ik vind het een geweldige versterker voor het gevraagde bedrag. Ik heb er direct 2 aangeschaft om een experimentele zelfbouw luidsprekersysteem elektronisch te scheiden. Hij is mooi klein vanwege de klasse D configuratie en wordt daardoor ook amper warm. Ik kan alleen maar een positieve punten bedenken. Deze versterker doet gehoormatig niets onder voor de z.g.n high-end versterkers in klasse AB en A.

Build Quality and Design : The Fosi Audio ZA3 delivers in terms of build quality, with a sleek and minimalistic design. It feels sturdy and solid, but what truly stands out is how Fosi managed to pack so much quality into such a compact unit. The metal chassis feels durable, and the overall construction is as good as, if not better than, many amplifiers at much higher price points. While compact, the ZA3 is not flimsy, and every dial and switch gives the impression of longevity. In comparison to high-end models, the design isn’t just practical but aesthetically pleasing. The Mono Mode switch is a highlight, giving flexibility for those wanting to upgrade their audio setup with mono block configurations without investing in much larger, more expensive gear. Fosi is known for squeezing high-end features into affordable packages, and this product lives up to that reputation. Ease of Use : The steps of the installation are easy, but the manual input switching between RCA and XLR could be seen as a disadvantage for some users, especially when compared to fully automated systems found in high-end amplifiers. That said, this is a minor inconvenience considering how user-friendly the rest of the system is. For those who prioritize quality over convenience, the manual toggle feels like a small price to pay. A unique feature here is the subwoofer integration. However, users should note the presence of DC voltage at the subwoofer output during shutdown. This could affect sensitive equipment over time, so more demanding users may want to look into additional power management solutions. Sound Quality : This is where the ZA3 punches above its weight. The sound clarity and detail are superb for its price range. When driving both bookshelf and floor-standing speakers, the amplifier delivers a clean, full-bodied sound with minimal distortion, even at higher volumes. The bass response is tight and clear, but one minor drawback is the lack of an equalizer. On the one hand the bass is very good but on the other hand the amount is not enough.The problem is not due to the power amplifier but much more to the speaker. In fact, it shows that the amplifier is no longer the bottleneck in the system, but rather my own DIY speakers. In mono block mode, the sound performance rivals amplifiers costing several thousand euros. It handles high-resolution audio with ease, and the stereo separation becomes significantly more distinct, adding depth and dimension to the soundstage. The Texas Instruments TPA3255 chip really shines here, pushing the ZA3 into a league above most budget-friendly competitors. Compared to high-end amplifiers, the ZA3 can hold its own, particularly when considering price-to-performance ratio. While high-end models may deliver slightly more warmth or analog richness, the ZA3 is incredibly neutral and precise—qualities that audiophiles often seek. Power and Efficiency:  The power output of the ZA3 is impressive for its size, particularly when paired with the right power supply. The 155W per channel in stereo mode and 240W in mono mode allow it to drive demanding speakers with authority. Even at high volumes, it doesn’t distort easily, a hallmark usually reserved for amplifiers at much higher price points. It’s efficient as well, remaining tepid even under extended use, and the low power consumption is ideal for long listening sessions. However, users should be aware that achieving the amplifier's full potential requires an upgraded power supply, which adds to the total investment. Versatility and Compatibility : The ZA3’s versatility is a major selling point. Whether you're using it in stereo or mono mode, the amplifier adapts well to different speaker setups. Its compatibility with both RCA and XLR inputs makes it a flexible option for users with varying audio gear. Comparison with High-End: Amplifiers Compared to amplifiers in the high-end market costing several times more, the ZA3 proves to be a serious competitor. Its sound quality, versatility, and power output are on par with much more expensive models, such as offerings from Audionet or Denon. While some audiophiles may argue that high-end models offer marginally better warmth and richer tonal characteristics, the differences are minimal when accounting for the price difference. For users on a budget who still want audiophile-grade performance, the ZA3 is an excellent alternative. It doesn’t just compete in terms of price but delivers a sound experience that challenges the notion that you need to spend thousands for top-tier audio. Final Verdict:  The Fosi Audio ZA3 stands out as an amplifier that offers excellent value for money. With its detailed sound, solid build quality, and flexibility in both stereo and mono configurations, it offers performance that can rival high-end amplifiers. While there are a few minor flaw like the subwoofer DC voltage issue—these are overshadowed by its overall performance and value. The bass response, while very good, may seem a bit limited due to the lack of an equalizer, but this is more reflective of its linear performance. The amplifier’s strengths reveal that the shortcomings likely lie in the speaker setup, not the amplifier itself. Whether you’re an audiophile looking for a cost-effective upgrade or a casual listener seeking quality sound, the ZA3 is a strong contender in any setup.

Perfect communication and rapid delivery, fair costs. Amplifier is used to connect a TV to external loudspeakers.

Klinkt heel erg goed.

Schnelle Lieferung klasse Ware, super Kontakt.... Gerne wieder

By Volker on 16 June 2024

Dit ding is een aangename verrassing. Ik was altijd wat bang om Chi-Fi dingen te kopen, maar de klank is veel beter dan ik had verwacht. Het heeft ook meer dan genoeg power om mijn oude B&W DM2a deftig aan te sturen en het feit dat het een volumeregeling heeft maakt het makkelijk te combineren met mijn Rodec Bunk-01 preamp. Zeker een aanrader met zo'n kleine footprint. Voor die prijs kan je niet missen.

Mooi helder geluid ,genoeg vermogen,en strakke bas,

By Ruud on 24 May 2024

Hopla en weer twee van die geweldige Fosi’s gekocht. Eigenlijk meer dan vijf sterren, met een andere betere Op-Amp. Het is en blijft ongelofelijk wat die versterkers kunnen produceren, mijn mooiste en beste versterker ooit En ik heb ondertussen aardig wat versterkers gehad :) ook class D versterkers van genomineerden merken ;) Belangrijkste voor mij is, dat ze ook problem los met Elektrostaten spelen…

By Martin Petersen on 23 May 2024

Echt een geweldige versterker. Had ik het geweten had ik ze hier besteld, ik heb ze direct bij Fosi in China besteld. Maar dit is veel goedkoper en makkelijker! Ik kreeg ze ook 1 per keer met weken ertussen. Ze zijn niet aan te slepen namelijk. En het is echt niet alleen hype. De eerste weken dus in stereo mode gespeeld. Dat was al goed. Ik moest alleen splitten naar de subwoofers. Ging prima met welke speakers dan ook. Met Magnepan 0.7's ook p...

By Jeroen van Gent on 22 May 2024

Whooow dit is de beste aankoop sinds jaren voor mij. Wat een geweldig mooie en leuke versterker is die Fosi ZA-3 Als je hem met de standaard Op-Amps gebruikt is hij wel aardig, maar met de betere Op-Amps wordt hij zelfs waanzinnig goed
