About this item

Dual-Mode Innovation: This new generation mini amplifier offers both stereo and mono modes, adapts flexibly to your diverse needs, allowing seamless mode switching. In stereo mode, it delivers a robust output of up to 180W, while in mono mode, the power soars to a maximum of 235W. Pair two ZA3 units in mono configuration to create a powerful audio system, significantly enhancing your listening experience
Richer Connectivity: Debut amplifier with balanced input and trigger in, the ZA3 features a balanced combo audio signal input connector supporting both XLR and 1/4" TRS plugs. This design minimizes interference and reduces noise floor. The 12V trigger-in connector enables synchronization with other devices, streamlining the process of turning on/off without individual operations
Audiophile-Grade Components: The ZA3 features the TPA3255 high-end Class-D amp chip and utilizes premium Japanese NCC, ELNA, and German WIMA capacitors, and Japanese Sumida inductors for exceptional audio quality. With a SINAD rating of up to 89dB, an SNR of up to 106dB, and a low noise floor of only 150μV, it delivers exceptional clarity and low distortion
Advanced Heat Dissipation: Based on V3's groundbreaking heat dissipation design, we upgraded ZA3's cooling system by featuring a larger chassis, moving vents to the sides, and adding dust covers to achieve better ventilation for a sustained and stable high power output
Enhanced Scalable Fun: Personalize your audio experience with the op-amp rolling feature! The ZA3 stocks five swappable op-amps for left and right channel outputs, balanced input, and subwoofer output. Experiment with compatible DIP8 dual op-amps such as Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4558, LM4562, LME49720HA, etc. to fine-tune your sound to perfection

Needed something compact to run my bookshelf speakers in a limited space area.

Bought a second ZA3 to match up with my other ZA3, both set in MONO modes.

These sound great and have plenty of power running my high efficiency speakers.

Great performance and great price!

It sounds great as a budget amplifier, I've been using it for over 6 months now and it still works great. I wish it had a remote to be able to turn it off and adjust volume. It's nothing exceptional tho, doesn't match higher end amplifiers of course but it's hard to beat at around it's price and a very good alternative for a soundbar.

Using this in my basement for retro gaming. Pushing paradigm monitor speakers and a paradigm sub.

Clean sound. Great channel separation. I wish there was some form of EQ. (That gets handled by the audio source).

Way better than I expected.

*review update*

I swapped out the op amps. Put in Burson v7 vivids. Unreal. Really made this little amazing amp shine even more.

Also bought a second. Running them in mono mode. AMAZING.

What a great little amp. I have had a few expensive HiFI set ups in my life, but now that I have downsized, I wanted something smaller. This, when hooked up the the WiiM Ultra that I also bought recently and a good pair of bookshelf speakers (Dali), sounds way more impressive than it should. The fact that I can use this as a mono or stereo is something I've never come across before, and that opens up its versatility even more. Recommended for those looking for a less expensive, but still good quality, amplifier base.

Excellent petit amplificateur qui n'a pas a rougir face au grande marque.
Je l'achète pour la 3ème fois et j'en suis vraiment content.
La qualité est au rendez-vous et une patate en mono, même si la stéréo se débrouille bien.
Possibilités de faire des modifications avec de nouvelles OP (voir avec FOSI), d'ailleurs c'est ce que je vais faire pour leurs donner plus de pêche ainsi que de finesse au niveau du son
La connectique est impeccable, dommage qu'il n'y est pas de sorties cinch voir XLR (mais le prix aurait été différent).
Je recommande les yeux fermés

Fun little amplifier with great versatility for expansion into hifi
Reviewed in Saudi Arabia on April 15, 2024
Verified Purchase
I used this amplifier to drive the JBL 530 which is a 6 ohm nominal load and 86 db/w sensitivity speakers and it drives them at all levels easily with no noise whatsoever, the character of this speaker/amp pairing is a bit laid back in mid range, fast and tight thumping bass, slightly rolled off in the treble,

I’ve found the best dynamics with the potentiometer somewhere between 11:00-01:00 o’clock and the windows volume betwen 60-70%(Vrms of 1.95V DAC line-level output), this gives me about 70 db average listening level with 30+ db of dynamics headroom.

I’m looking to try other op-amps in this amplifier and see how it affects it tonally, overall I’m plenty happy for such a good price and lower size profile that this amplifier provides, well done Fosi!
