Fosi Audio MC101 Bluetooth Stereo Amplifier with VU Meter 2CH HiFi Receiver

Thx for extraordinary customer support.

A compact design for the output. Great for small room or office. Good looking front end with the Vu meter although you have to look real hard to see its movement. The volume at low levels seems out of balance (l-r) have to increase to at least half to achieve balance. Overall a good value for the price.

Doet precies wat ik verwachtte: oude speakers zonder versterking weer activeren. Mijn twee speakers van 150 watt met een bass gedeelte worden perfect aangestuurd. Wellicht een keer een sub proberen aan te sluiten om echt laag te ervaren maar is in feite niet nodig. Apparaatje is lekker compact en oogt leuk (boven op de speaker).

I am using the Fosi MC101 together with an old pair of Energy XL15B bookshelf loudspeakers to stream audio from my iPhone over Bluetooth.

My overall impression of the MC101 is very positive. It sounds excellent, and has plenty of power for near field listening. Bass is very well controlled, and the noise floor is very low (much lower than I am used to - there is basically no audible hiss.) Bluetooth appears to work flawlessly with the iPhone 14.

The MC101 is also quite nicely built - the compact enclosure is made from some sort of metal. It is heavy enough to stay put, which is an important consideration for something so small! I love the VU meter, but usually I listen at too low a level to make the needle dance much.

Overall, this product exceeded my expectations and I would very much recommend. Great value!

Having been so impressed with the V3, I thought I'd try the MC101 as the core of a second system. I am not disappointed. Like the V3, I find the noise floor is imperceptible, the dynamics are good and the detail excellent. Again, I also find it is quite neutral in sound, though the tone controls allow fine tuning the sound in quite a nuanced way to the speakers and the room.

In respect to the design, I like the look and feel of this amplifier. Controls are clean simple and have a nice tactile quality. The VU meter is a fun touch, but is also the only negative for me as it is insensitive to high output modern sources; vintage sources tended to be lower in output, so you had greater volume control. I primarily stream to the amp via AirPlay (a typical 2.0 VRMS) and unless the volume is turned up to silly levels, the needle does not move at all. Different sources make no difference for me. It’s a shame. Perhaps some form of sensitivity switch would be useful, or recalibration at the source.

Bluetooth, I find, is the last resort for most listeners. It’s okay with the AAC codec, as background perhaps, but is noticeably less detailed, dynamic and quieter as a source. I’d prefer to see it replaced with, say a 3.5mm stereo jack input option, as space for another set of RCA inputs may not be possible.
