With a power output of up to 600W, it can effortlessly drive 2-8Ω speakers, delivering impressive sound quality. Its compact size makes it suitable for various applications, from bookshelves and desktop setups to home theaters. - Audiophile-Grade Components: It features the TPA3255 high-end digital 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 88dB, an SNR of up to 110dB, and a low noise floor of only 140uV, it delivers exceptional clarity and low distortion. - Innovative Cooling: The V3 stands out with its groundbreaking heat dissipation design. Equipped with vents on the casing's top and bottom, and a whole-body heatsink design, it efficiently dissipates heat, preventing damage to components and ensuring optimal performance. - Scalable and Fun: Tailor your sound experience by swapping the stock NE5532 op-amps. V3 is compatible with a variety of 8-pin dual op-amps like Sparkos SS3602, MUSES02, OPA2604, OPA2134PA, OP249, AD827, RM4559, LM4562, LME49720HA, etc. - Worry-Free: Enjoy peace of mind with the V3 stereo amplifier. It comes with a 24-month warranty, ensuring reliable performance and customer satisfaction. - Note: The "Pre-out" level is NOT controlled by the volume control as the V3 is not an integrated amplifier, so the sound is NOT adjustable when you are connected to the "Pre-out". ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C36S8DCT | | Best Sellers Rank | #17,766 in Electronics ( See Top 100 in Electronics ) #37 in Home Audio Amplifiers | | Brand | Fosi Audio | | Customer Reviews | 4.4 out of 5 stars 1,226 Reviews | | Manufacturer | Fosi Audio | | Mfr Part Number | V3 | | Model Number | V3_32V/5A | | Unit Count | 1.0 Count | ## Images ![Fosi Audio V3 Stereo Power Amplifier Home Audio 300 Watts x2 TPA3255 Class D Mini Speaker Amp 2 Channel Audio Component Amplifier for Passive Bookshelf Tower Speakers for Desktop Home Theater - Image 1](https://m.media-amazon.com/images/I/51jOyYN2wnL.jpg) ## Questions & Answers **Q: Even if you put a 48v 11a power supply on it you would still be short of 600w, does this make any sense? is it really max 300w but miss advertised?** A: That number is misleading, it will never gets to 50watts **Q: Are each channel mono block? So I can send a differential signal to the rca inputs. Thanks!** A: https://www.amazon.com/SPRODIO-Converter-Adapter-summing-SC21/dp/B0BRZCGY29/ref=sr_1_1?keywords=stereo+to+mono+converter&qid=1684854327&sr=8-1 **Q: Total new to this. i have a pair of sony sscs5 bookshelf speakers. i don't see a way to add a subwoofer. am i correct?** A: You either need a 3 channel output device (most basic devices without a sub out are just 2 channels) that can run straight to the sub, or a subwoofer that can accept RCA, and split the RCA signal that would feed this amp before it goes to the amp with two RCA splitters or a stereo RCA splitter cable. **Q: Does the V3 come with a power supply? If so, which one?** A: It comes with a 5A, 32VDC power supply. It can put out 160 Watts of power (5A x 32V), not 32 Watts as another answer incorrectly states. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great sound without complexity *by G***R on 5 July 2026* Superb sound, powerful performance, minimalist design ### ⭐⭐⭐⭐⭐ Good volume *by B***H on 17 June 2025* I've eventually set my V3 amp up.

Happy. ### ⭐⭐⭐⭐⭐ SEMPLICEMENTE SORPRENDENTE ! *by R***K on 28 August 2023* Ho acquistato il Fosi Audio V3 con molta curiosità dopo aver provato diversi amplificatori di classe D (tra cui Aijima) sono rimasto colpito sin dal dal primo ascolto. Sono un appassionato hifi da circa 35 anni, utilizzo anche amplificatori Mc Hintosh, ma ero davvero curioso di provare un oggetto così piccolo ed economico un grado di mettere in discussione le convinzioni dell'audiofilo più conservatore. Stiamo parlando infatti di un amplificatore senza fronzoli e colorazioni, con la sola manopola del volume, ma che assolve egregiamente al suo compito: SUONARE BENE! Naturalmente il tutto va inserito in un contesto adeguato che ritengo sia essere un ambiente di piccole o medie dimensioni oppure, come nel mio caso, un sistema audio da PC con monitor. Ho realizzato un impianto con il DAC Topping E50, Fosi Audio V3 e le ottime Cabasse Surf (piccole ma testarde con un efficenza di 85 Db su 8 Ohm) devo dire che sono più che soddisfatto del risultato ottenuto, testato con diversi generi musicali il suono risulta abbastanza lineare ma non privo di dettagli e dinamica; bassi rotondi e mai invadenti, alti molto dettagliati e puliti, le voci che spiccano per naturalezza. Insomma un piccolo gioiello che sicuramente vale molto più di quello che costa e che ti lascerà a bocca aperta ! Riguardo la potenza dichiarata di 300 W per canale va considerata con un alimentatore da 48V 10A per un impedenza di 4 Ohm, nella maggior parte dei casi invece, ovvero con l'alimentatore di serie da 32V 5A, tiriamo fuori una potenza di circa 50-65 W rms per canale su 8 Ohm, una potenza di tutto rispetto soprattutto perchè priva di distorsioni al massimo volume. La manopola del volume ha un controllo di tipo logaritmico, per cui bisogna girare parecchio prima di avere un buon volume di ascolto ma non abbiate paura di farlo; il grosso della potenza è nascosto nella parte finale. Sulla componentistica interna vi rimando ad altre recensioni più dettagliate, ma sicuramente l'ottimo TPA3255 (già presente su Aijima A07 e Fosi Audio BT20A) assieme ai celeberrimi Op amp NE5532 costituiscono ormai un abbinamento collaudato, ma il Fosi Audio V3 si differenza dai suoi rivali per l'utilizzo di una componentistica interna di alta qualità, in particolare condensatori ed induttori Giapponesi e Tedeschi. (potete trovare ulteriori dettagli sul sito ufficiale) e vi assicuro che la differenza con gli altri amplificatori si sente, e si sente davvero bene:) Degno di nota anche l'originale sistema di dissipazione del calore posto al di sotto del chip e collegato a tutto lo chassis; un sistema davvero molto efficiente che difficilmente manderà l'amplificatore in protezione. Molto interessante inoltre la possibilità di sostituire gli Op amp con un altro modello, sul sito Fosi Audio potete trovare alcuni consigli tra cui gli Sparkos SS3602, MUSES02, OPA2604AP, OPA2134PA ecc... (la lista è davvero lunga) facilmente sostituibili perchè gli NE5532 sono montati ad incastro su un adattatore DIP8. Personalmente, preso dall'entusiasmo del nuovo prodotto, sto testando il Fosi AUdio V3 con i nuovi Op amp ORACLE II-02, il risultato è davvero entusiasmante, ne scaturisce un suono non migliore di quello prodotto dagli NE5532, ma sicuramente diverso, più caldo, molto più simile agli amplificatori tradizionali o, se preferite, ad un valvolare. Insomma il Fosi Audio V3 rappresenta davvero un grande balzo in avanti per l'azienza sperando che continui su questa strada; un prodotto chenon ha paragoni nella sua fascia di prezzo e che per come suona vale almeno 5 volte di più.
