Douk Audio G3 PRO Bluetooth 5.0 Power Amp & Headphone Amplifier, Support APTX, with DAC chip, 100W x 2, Works for 2.0 Channel Passive Speakers (Silver)

I bought this amp to power a pair of deck speakers. Using bluetooth, streaming TidalPro'sVery quiet noise floor. no loud "click" when powered on as reported by users of similar products. DAC has excellent clarity especially in mid and high range.Bluetooth range is crazy good. Walked down the street with my iphone, and the music faded from distance before the bluetooth gave out. I'll need a second person to tell when the signal dies!Con'sBass is a little distorted at high volumes...BUT i'm using a $200 pair of Paradigm speakers that I bought at Best Buy a few years ago, and they've been outdoors over a couple winters. So until I test this unit with a pair of indoor speakers I can't really fault the amp. I'll update my review when I test on known speakers.Can't tell if this is worth the extra $20 of some of the others people have reviewed, but the overall sound is excellent.

The power supply unit was dead out of the box. Nothing would turn on and there was no voltage measured at the end of the PSU connector.Normally, is be ok with that and just get an exchange, but the shipped item is clearly a returned unit. There were scratches all over the PSU and amplifier case. Likely it didn’t work for the first customer, or the first customer broke it, and it was shipped out again without QC.Without hearing the unit it’s otherwise difficult to do a full review. I will say the build quality is aweful. The switches and control knobs feel plastic and flimsy and the uniformity on the aluminum coating is terrible. The screw terminals are equaly cheap.

Well guess what, it did and has stood the test of time. It's worth the spend people.Why did I give one star? Because in less than 9 months, amp is clicking on and off. It just started, it can't be heat or overloaded. Regardless, it WAS a great amp, but just couldn't stand the test of time. My recommendation - DON'T BUY.

I've been running the amp for a little over a month to power some 100w outdoor speakers and it does great. Pros: easy to connect to bluetooth, lots of power for the size, looks sleek. Cons: if I'm running through the tv and my phone is still connected to the bluetooth feature it occasionally cuts out until I remember to disconnect my bluetooth from my phone, no remote or other way to control volume except manually.

When it works, the sound is phenomenal. I was using this in a whole house streaming application with PlayFi, and connecting through the RCA inputs. Amp repeatedly shuts down into some kind of self protection mode. takes me around 10 times unplugging the power supply and plugging back in at very low volume to get it to come back on. AND every time the amp sparks very badly from the socket. (known issue with these) Reached out for Tech help 2x and no response whatsoever. Amazon did fully support the written 90 support.

I paired this with two Boston Soundwave's and with a 24v psu that is working. I couldn't be anymore happier for the money spent.I had an extra 12db gain antenna from a PoE camera and I can walk around my whole yard with my iPhone 8 and stay connected.Seller was good at taking care of a doa power supply but unfortunately the slow boat from china is well SLOW.

This little amp is impressive. I pared it with 2 Polk Atrium 6 outdoor speakers and attached a 9db gain 2.4ghz antenna from an old computer tower WiFi card. I have Bluetooth connectivity on my whole property. I will say that the speakers make all the difference in the world. When I received this amp I initially connected it to my Klipsch towers and could not believe the sound quality and volume this amp was able to produce. I am a very satisfied with this product and have recommended it to multiple friends.

Power supply came DOA so yeah. I used an old power supply and the amp works fine. The knobs are rough turning but no pop when turning amp on or plugging up. Wish the power supply worked cause it was 24v6amp and mine is 24v3amp so it’s not quite as much juice going to amp and speakers

This is a great little amp with lots of power. Took 1 minute to set it up and connect my TV as a Bluetooth input. My only complaint is that the speakers do not shut off when you plug it not the headphone jack. I can't think of any situation where I would be using speakers and headphones at the same time.

Update, my big speakers ate this amp for breakfast, as everyone said they would. So, didn't work for me, still a decent little amp, but for low impedance speakers, use something else. The manufacturer of my speakers claims that they don't drop below 4 ohms but I don't think that's the case. Or, something else happened. Yeah, I was playing bassy music at high volumes, but now this amp doesn't work at all, constantly wavering distorted output with any speakers. Oh well.

I bought this nice little amp to listen to movies while everyone is asleep in the house. (connect it with my samsung's tv bluetooth option)Tried the unit with some Sennheiser HD598 and HD6XX and it has no trouble driving both of these pairs.I've even put it on top of one of my side home theater bookshelf speakers and I get no interference at all.Only time will tell if it last long enough but so far its been working great (only about 1 week use though)

I bought this for two large Boston Acoustics floor speakers from the 1980s. I was worried that the amp would not be able to power the big speakers and give good volume. However, the sound quality and volume are great. I am playing MP3s on an iPOD and connecting by Bluetooth. So far I am very happy.

Big sound in a small package. Sounds great with both RCA or Bluetooth 5.0 Aptx. Well made with quality components. Supplied power supply though is not of the highest quality, but it can easy be swapped with a quality unit.
