Fosi Audio MC331 Tube Integrated Bluetooth Amp

Fosi Audio MC331 Tube Integrated Bluetooth Amp first impressions

I am very satisfied with sound and design. MC 331 with original tubes are easy to install and they work perfectly. Amp has enough power to push my passive Wharfedale Laser 50 speakers to work like a charm.

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
