I have to admit my expectations for this unit were kind of low based on the price and some reviews I had read. Honestly, I am blown away by this amp. The build quality is impressive. This is not a flimsy piece of plastic but a brushed aluminum case with heft and solid components inside. It is heavy. It has all the inputs(including optical) and features galore. Sound quality is not audiophile quality but easily outdoes anything even close in this price range. The unit has a fan that runs constantly while it is powered up. The fan is kind of loud while nothing is playing but I don't notice it during playback. The supplied rca cable is low quality but who doesn't have several already laying around? Get a gold plated one and toss the included one. The Bluetooth range is about 25 feet if there is a heavy (or multiple) wall in the way. My only real complaint is the remote. Particularly the volume buttons don't appear to work in any mode that I have tried so far. Huge bummer!! Lots of people complain because it is listed as 3000 watts. To be clear, that is peak wattage. As far as I can tell the average wattage is at least 300w per channel. I don't like that marketing style but it is common place in the industry(especially for budget options) so you just have to know how to interpret it. Can't blame them for how the marketing game works. I Can't speak for durability so far but I am actually very pleased with my purchase thus far. Let's be real... I mean for $120 you can't even *look* at a used namedbrand 20 year old home theater system that matches these features and power.PROS : Price, Build Quality , & FeaturesCONS: Remote Functionality. Ambient NoiseIf you want audiophile sound quality, silent operation, and perfect functionality go spend several thousand dollars. If you don't want to break the bank and just want a decent unit to put in a cabinet or on a rack to run your media center on then don't hesitate to get this unit. You won't find better quality without spending at least $500 dollars in my opinion, and will likely lose features in the process. The remote thing is a huge turnoff for me but I still give 5 stars because this thing is *incredibly* affordable. I have yet to reach out to tech support on that issue, but have workarounds by using other remotes for my devices... Hopefully it can be resolved. I will update review pending that interaction and any durability concerns.
