I’ve been using the Fosi Audio V3 Power Amplifier together with the Q6 DAC, and my experience has been fantastic. The V3 amp truly stands out in terms of clarity, power, and versatility. It's compact, robust, and unexpectedly powerful for its size—driving my speakers with tight bass and a very neutral, transparent sound signature. The build quality is excellent, and all controls feel precise. There’s no noticeable hiss even at higher gain settings. Pairing it with the Q6 DAC further elevated the sound quality. The Q6 delivers clean, detailed output with impressive separation between instruments and a very quiet noise floor. Connection was flawless and setup was straightforward—plug and play. I tried it via both USB and optical inputs, and it worked perfectly in both scenarios. Customer service from Fosi Audio has been prompt and helpful. They genuinely care about users and actively respond to questions and suggestions, which leaves a strong positive impression. Overall, these products offer fantastic value for anyone seeking clear, powerful, and honest audio reproduction at a reasonable price. Highly recommended for audio enthusiasts looking for reliable yet affordable gear.

J'adore Fosi Audio, ils font de bons produits avec un rapport qualité/prix plus qu'excellent. J'ai actuellement : 2 ampli mono V3, deux petites merveilles qui alimentent les Magnat transpuls 1500 Le DAC ZD3, le ZH3, le GR70 Tout ça pour le salon. Et pour la chambre : Les enceintes SP601 qui attendent le MC331 que je vais prochainement m'offrir. Ils sont partis de pas grand chose, mais on vite grandi en 8 ans et ça c'est génial. Merci d'être à l'écoute de vos clients que ce soit pour l'élaboration d'un produit ou juste d'un problème. Vos produits sont de mieux en mieux et ça, c'est assez rare dans cette gamme de prix, encore merci Fosi Audio.

Bought the mc101 preamp. It has fantastic audio quality and is built really well. Day one a knob for the speaker wire fell off due to over tightening but otherwise really good.

Hi Y'all. I bought a Fosi ZD3 today. Its connected to a vintage Quad 33/303 amplifier set up. What to say? It's been running all afternoon. Amazing sound. Now I use the Marantz CD6000 purely as a transport. The TV via Toslink sounds so much better. All in all, it is a bargain.

Just received PH05 5 way headphone amplifier. Can’t comment on reliability, but quality, both of construction and sound, are great at any price, but really remarkable at £50. Music actually sounds more immersive through this than direct from source - I don’t know how that’s possible. I haven’t read other reviews, and can’t comment on other products, but this one is great so far.

I've bought a bluetooth amp and a bluetooth volume control. Both excellent products and a pleasure to use. Recently ordered some other stuff from them. I messed up my order and accidently ended up ordering double of some items. I raised the issue from their website and they very quickly fixed the order

Had this little beauty for several months. It does what it says on the box. It’s a, tiny, reliable Bluetooth amp. For the price, there is nothing to touch it. Yes, you have to switch it off, at the amp, before plugging in or disconnecting. But that should be no shock, as its said clearly, in the instructions. Ivenot had to deal with the Chinese company. As in the U.K., it’s the vendor that’s responsible for guarantee repairs or problems. But, as I’ve seen here. “It didn’t do what I thought/wanted. Isn’t the makers or vendors fault. It’s entirely down to the purchaser. Pick one up, you won’t be dissatisfied.
