Great little amp. Using it in my kitchen with Polk RTi A3 speakers. I'm using a chromecast with it to sync to the rest of my house, but the bluetooth function does work well and paired very quick with my Samsung S7 phone for testing. Nice build quality, no complaints about sound quality either. I'm not using this is a "critical listening" environment, but I do usually notice when things sound good, and this does. I could have honestly used it's "little bother" the Cab-AMP30, which also sounds pretty good. (I got both, using the smaller amp at my computer) but I wanted a little more headroom for days when I have the music up louder or if I decide to power a slightly larger speaker in the future. Keep in mind that all of the class "D" amps like this are rated by the capacity of the chip, not the output. This can't put out more than 36 Volt x 4.5 amps = 162 watts. There is great video on this here explain house the class D amps work: https://www.youtube.com/watch?v=iO-MVAnA9f4 I'm happy with it "even at" 162 watts, I knew it before buying. Thought I'd share with others looking at the class D amps. I wouldn't try using this speakers that are large and inefficient, but if you have some nice bookshelf speakers or even efficient towers this will be more than enough unless your looking to shake the house. Pros: small, clean looking, well made (looks nice), bluetooth if you want it, easy input switching on front, plenty of power. Cons: Not truly able to output 200w of power, but that is a not unique to this class D, it's common to all of them, and this unit is better priced than many of its competitors that have the same restraints.

It's not bad, had a bit of a scare when first using it. I plugged in the power cord and then went to plug in the adapter part into the amplifier, and a huge spark blew up. I was worried the amplifier blew, but it still worked. I believe the spark was caused because of the metal body of the amplifier. The instructions do say plug in the adapter to the amplifier first but this is a pretty dangerous design flaw. I am not sure if the quality of the sound has been affected because of this. The bluetooth function isn't the best. After a certain volume level, the sound becomes fuzzy and grainy.

Dear Customer This kind of the spark is caused by the capacitor is drawing a large current of power in a fraction of seconds, this is considered normal and the spark will be only at the very moment that you plug-in the power adapter, but we still recommend you to avoid doing that next time since it will generate a huge amount of heat at that short instant and might going to have a slight chance to burn and carbonize the housing on the connector where the spark had been generated. it will not affect the use of the amplifier but will make the connector part looks and smells burned. Best Regard

Le produit est vraiment intéressant, ingénieux, de qualité et solide. J'avais un speaker double de 200W qui poirotait dans un coin. J'ai acheté le produit sans avoir trop d'attentes personnelles. En l'espace de 10 minutes, j'ai câblé le haut-parleur à l'amplificateur sans avoir aucune surprise. Toute la famille l'utilise au max. Très bon achat ! :)

Rien ne fonctionne à part que je me connecte avec mon iPad ou Iphone. Je fais un échange du produit cependant alors je pourrai modifier mon évaluation.

This amplifier didn't work out as expected. Got a lemon out of the box.

Bluetooth died after 6 months. No longer connects - tested with 4 different Bluetooth sources. Wasted my money.
