Fosi Audio MC331 Tube Integrated Bluetooth Amp

Awesome Iittle Product

I purchased this item based on information acquired from a source familiar with quality sound. I have a great pair of Martin Logan speakers and realized from sources I did not have the correct combination of amp to sound. First off I needed a DAC unit, a quality Bluetooth interface and the Martin Logan's love a tube amp. The Fosi MC331 fit all the necessary items. The quality sound I receive from the MC331 to the Martin Logan's is incredible and the price point makes the MC331 unbelievable !

Warm and cozy

Nice warm sounding amp. This is a great amp for headphone and nice soft/relaxing music. It also has no problem powering my bookshelf speakers

Awesome little amp. Can't beat it for the $.

Very small footprint but sounds great even at pretty high volume with my Boston HD9s paired with a 12" powered sub (Dayton Audio). Unit LOOKS really nice as well. Great design, great aesthetic, and extremely solid build quality. I love the look of VU meter and the tubes. Its an amp I happily display in plain sight rather than just tolerate. Remote control is a welcome feature as I am using this to run audio from my RokuTV via the RCA input. The only suggestion I have for Fosi would be to include more operational detail in the paper user manual. That said, customer service was able to promptly and effectively answer my questions regarding default volume settings (defaults to 20% on power up) and bass/treble adjustments via the remote. Fosi really knocked it out of the park with the MC331. Bravo.
