Pros: Nice, warm sound!
Cons: powersupply, background noise
Just bought this amp (actually bought two, because of the pricetag!) and at first, when i powered it on, i was a little worried, as it wouldn't light up in the front, but i just left it their lying on my floor, and when i came back to my room it worked... *easy problemsolving* :)
This little mini amp sure have an amazing sound/price ratio, and with a little modifications, it actually sounds really great! the bass and clarity are a little boosted, while the mid sounds a little muddy, but overall it's definetly worth the 20£ i payed for it (with upgraded powersupple) I'm not an audiofile by any means, but i do own some headphones (ex: Sennheiser Momentum) and my uncle have some 10.000$ speakers, so I do know a little about sound... so back to the modifications i was talking about, recapping the whole thing makes it sound quite a lot better, but the biggest difference (I believe) was upgrading the powersupply; from the stock 12v 2a to a 12v 5a, as the stock one simply doesn't deliver enough power.
So overall this mini amp is definetly worth its pricetag, but probably not worth the "Hi-Fi" label. as one of the other reviews said: "You will not find anything remotely close to this amp's sound quality at this price range. But if you do have the budget to afford something better, that might be a better route to go."
