SMSL AD13 Bluetooth HiFi Digital Amplifier Audio Power Amplifier Stereo Amplifier 30W2 19V Mini AMP USB

This is a great amp for the price. It drives my Boston HD5 effortlessly and the sound is crisp and clear. The audio source is my PC through an external DAC. Mids and highs sound great, and bass is decent. Best suitable for jazz and classical. I was also surprised to find that it is able to generate a broad sound stage. It's internal DAC is decent, but I prefer my external one, and the bluetooth capability is solid and I experienced no issues setting up a connection with my android phone. I'm very satisfied with the performance of this little amp so far and I do highly recommend it.

This product is junk. It doesn't even come with a battery for the remote, which should be included at this price point. Also, the directions are not in English with the exception of how to replace the battery. When you try to go to the company's website, Google tells you that this website is trying to obtain your private information and blocks you from going into their site. I'm assuming the unit should automatically connect to Bluetooth on your phone but my phone does not recognize it. Don't waste your money on this product. I'm returning it today.

Very disappointing product. BlueTooth goes to sleep and will not reconnect to my Apple or Android devices until the amp is power cycled. I don't have this problem with other BT connected products I have.Sound is really decent though through a pair of Yamaha outdoor speakers.I think there is probably better BlueTooth amps out there.

Amplifier more or less ok, well sound and power, but remote control does not work.

High power. Small package. Very low distortion at max power. Simply amazing. Remote works well. Bluetooth is flawless. I never write reviews but this one had to happen... I looked at lots of small Amps before chancing this one... If your speakers are quality you won't be disappointed!

What a terrible product. The unit was DOA on arrival.

A: Not much that I can see. I've actually been using mine to power an outdoor system for the past two years and it works without flaw. Well, I admit the Bluetooth reception is marginal, but I don't like BT SQ anyway. So I normally use a 3.5mm cable from my tablet or phone. Lately I brought it back indoors and have it playing (alternately) through some Harbeth 30.1s and Polk RTiA7 speakers. Liking it either way. Maybe I'm just easy to please. However, I do wish it had a sub out for indoor listening. Not critical with jazz but missed a bit with serious rock & classical.
