I am using these to test a setup with Dayton Audio BST-1 bass shakers. Currently I have one setup on the chair, and I am planning to use a second one in series at 8hm.But for now this amp has plenty of power with default gain from minidsp processor. The bass-shaker response is powerful and direct.I will try to update the review as soon as I have completed the setup.

after the internal amp on my Klipsch SPL-150 died a tragic death(bad design), i made a new, passive sealed enclosure for the 15" subwoofer, 95 liter internal volume. The signal it`s getting is from my Denon AVR 1600h, so it has LPF and all.This little Fosi amp handled 4 seasons of series so far, as a subwoofer amp. It does get warm to the touch: 40/45C after a couple of hours of playback. I`m not even going to try to repair the original amp. This one works enough for me!

Offers a lot of drive and accuracy.A/B compared It to an Audiolab A6000's and then you do notice the A6000's are just a bit more detailed and nuanced, but It's always in control. sounds big and has a very pleasant timbre. They are very easy to listen to. And we're talking about budget here, where my reference are between €500 - €5000. So, for desktop usage, what these are primarily intended for (i think) this is awesome. But also If you have low space situations and/or don't need all the extra's most (integrated) amps come with nowadays these could serve your purpose, and with confidence.That said, I wouldn't be very comfortable placing these in a closed cabinet, because they run seriously hot, even in an open space. Especially when you stack them. To the extend I'm worried about safety. I already read somewhere else somebody did get smoke coming out of these. Maybe It's BS, but It wouldn't really surprise me If you know they shipped these with reversed polarity for a while. That says something about their quality control ... They don't take It so seriously.It did make me decide to return them ... but men, they sounded good though for the price. If only those Chinese brands could get their quality control and regard for safety in order ...

Lekker veel vermogen met een redelijke geluidskwaliteit. Voor het geld een goed geluid maar niet te vergelijken met een echte klasse A versterker daar kan het echt niet tegen op.

I really enjoyed the sound and punch of this amp. However, it's not a match for a proper integrated amp like the Audiolab 6000A. It sounds quite punchy but lacks finesse, smoothness, and maturity. It's not for me, but if you are really tight on space, this amp will get your speakers rocking!

Absolument bluffant, j'en ai acheté 2 pour alimenter mes deux triangle tetha qui étaient directement reliées à un amplificateur Cambridge CXA61. Les deux blocs sont reliés dorénavant à un ampli pré ampli casque Fiio K7. Le son est juste magnifique les basses sont rondes et les instruments parfaitement situés. À ce prix je ne vois aucun équivalent. Je vais passer une nouvelle commande pour mon autre paire d'enceintes.

I had read some reviews, as I am interested in this market a lot, already owning a Fosi V3 and a pair of Aiyima A07 Max's... I had very high hopes for the Fosi V3 mono amps, and was not disappointed! Fresh out of the box they were a little tight and congested sounding, just a bit-no blooming of the sound...Well, 5 hours later and wow!! What a difference! The sound-stage is deep, wide and very clear, with no shortage of power, that's for sure! They sound so good they have already replaced my other monoblock amps! Bass is deep and very tight, the midrange is clear and open, highs are not shouty but again clean and well balanced top end. Excellent input choices (RCA and XLR) and simple controls... Having heard several of these TI 3255 chip amps, all have a similar sound, but the additional realism of the V3 mono is quite audible! And you can swap audio op-amps as well! A killer deal on the amps right now! Buy a pair- you won't regret it! :)Edit: I've been listening to these V3 mono amps for about a week now, and I am BLOWN away by the amount of sound these amps reproduce! True giant killers! I'm more than pleased with these amps! Buy some! :)

Ne ho presi due per avere gli alimentatori separati. Presi da una settimana e dopo una trentina d'ore si stanno ancora rodando, infatti il suono cambia di giorno in giorno.Buona la qualità audio: bassi, scena, timbrica, nitidezza ecc. ecc. Valgono i circa 250 € spesi. Se devo trovare un difetto, forse "impastano" un pochino quando ci son troppi strumenti in contemporanea (comunque giudizio certamente positivo).Come già segnalato scaldano parecchio e mi sto organizzando per mettere un paio di ventole.

Tengo un equipo de clase media-alta y compré dos V3 por las buenas reseñas que a nivel técnico tienen en todo el mundo. Las van pasando las horas de funcionamiento, van sonando mejor.Utilizo de previo mi Streamer Wiim Pro-Plus y las cajas T+A Criterion TMR60 y la escena es tremenda, al estar los dos canales completamente separados, el sonido cálido y descriptivo, es un clase D con mayúsculas.

Muy buen producto Fosi.
