Review: Awesome product, small yet powerful all in one! - This is an awesome product at this price point. but beaware of the package contents. It is highly recommend to make an unboxing video. i received 5725W vaccum tubes instead of 5654W these two have totally different characteristics for audio modulation. This is a very good quality product. Small yet a powerful all in one. Bluetooth connects seemlessly, RCA, Coxial, Optical ports all work smoothly. Headphones sound altogether different, in a good way. It Comes with a good quality power brick and a remote controller. Adds warmth to the audio sound and astethics to the setup with warmly glowing Vaccum Tubes and analog VU meter.

### ⭐⭐⭐⭐ Why this product is frequently returned. Bcoz read 👇
*by S***S on 22 October 2025*

The tube amplifier produces a warmth sound signature where mid tones (vocals) are clear, sharp and upfront, base feels muddy even when we increase the bass knob there is no difference in tune. Functionality (treble and bass knob functionality is not that good won't vary that much),the base is muddy, treble is rolled off ( less sharp more pleasent type) Most of peoples like punchier bass, great vocals and sharp treble which fosi audio mc 331 doesn't provide hence everyone might return this. Who can keep this: those who love genre: jazz, blues, classical. ( Not for rap/hip hop) Ratings: Build quality: 5/5 Looks: 4/5 classy retro touch (the yellowish light in vu meter is high) Sound signature: ?/5 depends upon your taste, can be tuned if you vaccum tubes are available. Russian voskhod tubes are matched for hip-hop/rap genre. Connectivity: 4/5 bunch of inputs but no input for u-disk(pendrive)
