The product is exactly as advertised. shipment was well packaged.
I bought this amplifier after watching/reading several very positive reviews. My experience is mostly positive but with 2 disappointments. Pros - Easily drives my pair of 100w at 8ohms bookshelf speakers with the supplied power brick - Produces a great neutral sound - The build quality is good - Bluetooth input and audio quality is good - Good price for the features and power Cons - Headphone output power won't drive my headphones at high volume, the volume just stops increasing. - The RCA input has a noticeable noise coming though the audio circuit which increases as volume is increased, presumably from the power circuit given its close proximity. Using the 3.5mm input on the front of the amplifier eliminates the noise. The seller was kind enough to promptly send a replacement believing it was a faulty amplifier, but the replacement has the same issue unfortunately. It's disappointing as circuit noise should not be an issue these days. I'm using the 3.5mm input instead.
