Brilliant sound, size and value

Reviewed in Australia on 4 October 2019

Colour: BlackVerified Purchase

Having several amps and receivers I was looking for a tiny amp but with enough power to fill my garden, roof garden or garage. Boy did I find it.

Hitched up to some old Yamaha bookshelf speakers the sound is awaesome and the bass and treble controls really welcome.

The unit is so small if you have external water proof speakers this would certainly be a great complement. Tiny enough to fit in palm, easy to move to where you want it.

No problem connecting to iPhone/Apple music on first attempt and has aux into.

A real joy!

Despite an expensive sound bar, top end 4K tv with good speakers it looks like my son is going to lay claim to it.

Impressive.

Excellent Purchace

Reviewed in Australia on 17 August 2020

Colour: BlackVerified Purchase

This little amp was exactly what I was looking for, it runs my Bose passive speakers well.

Pros:
- Connects pretty much instantly to my Laptop
- Great sound quality
- significant volume

Cons:
- If you are looking to use speaker cable that is thicker than 2mm (approx.) you will need to use banana plugs.
- Connections can occasionally be a little spotty, this has happened once or twice in the last month, but a slight reposition of the amp resolved the issue.

Cannot beat the quality for the price.

Reviewed in Australia on 30 July 2019

Colour: BlackVerified Purchase

Cannot recommend this little thing enough. Great build quality, pristine sound and ample power to shake my walls with these 50w bookshelfs. I dare say it's verging on audiophile capability. I agree with others though, the packaging deserved to be as good as the amp! If these were given a spruce up and sold to the mass market they'd sell like hot cakes. Will be buying another one in the future for sure.

Supercharge the home office!

Reviewed in Australia on 6 September 2020

Colour: BlackVerified Purchase

This is a great space saving and economical solution for a more-than-decent Hi-Fi system!

I wanted some decent quality sound for my office area and kitchen while in lock-down and I decided on this instead of powered desktop speakers. Paired with a pair of quality 6ohm satellite speakers and an active subwoofer(!), my house literally rocks! I generally only play on low volume. I have not dared to see how loud it can go - the volume dial typically sits at 9 o'clock position and it gets really loud beyond that. There's plenty of power in this amp! I'm no audiophile, but the sound is full, crystal clear and free of any static. The unit never gets hot (although it never gets to play hard either). Everything (computer, amp, sub, etc) is connected to same power board and there is no audible hum (caused by ground loop).

The unit has a quality feel overall and it looks pro (black version). The metal knobs have a solid, smooth feel and enough resistance for making small adjustments to bass/treble/volume. It even has a satisfying 'click' when powering on/off and there is no 'jolt' going to the speakers when powering goes on or off. The (removable) clear surface protectors were a poor aesthetic choice though, imho.

I keep the unit connected to an Alexa Echo Dot via bluetooth for all-day music and line-in from laptop for anything else. Alexa stays on all the time and connects immediately to the amp when powered on. The only minor annoyance is if you disconnect bluetooth to connect via line-in, you need to turn the amp off-and-on again to reconnect to bluetooth. Otherwise, Alexa says it is still connected if you try to reconnect, for some odd reason... There is no manual input selection. For my fixed setup and daily use, this does not bother me.

I can warmly recommend this as an alternative to powered Hi-Fi speakers or as a compact Hi-Fi setup. If you already have a pair of speakers collecting dust, it's a no-brainer!

For a cheap chinese built unit, it actually works well.

Reviewed in Australia on 8 August 2020

Colour: BlackVerified Purchase

I have being using the bluetooth amplifier for 6 months now and I must say for a crappy little Chinese built amplifier, it works pretty well. Bluetooth connects successfully all the time (all my phones and laptops connect with no issues at all), the sound quality is really decent (clean sound, no crackling), and it's loud enough to fill a very large room. I'm happy with it and surprised its worked this well, for the money. I would recommend this to anyone needing a cheap amplifier, to listen to stuff off your phone or laptop etc.

A clever design

Reviewed in Australia on 28 June 2020

Colour: BlackVerified Purchase

I needed to replace an old SONY amplifier used with my computer. I wanted power and a small size - I certainly got both of those. The unit worked out of the box and is supplied with a well made 19V power supply but I found out after purchase, you can only get the full 50W + 50W output using a 24V supply. I guess they do not want to push it to the limit. I will try with the higher voltage supply just for fun but the native set up certainly pumps out the volume. Because of the small size you should really use banana plugs to attach the speaker leads rather than the screw terminal posts; I found the whole thing a bit crowded with cable. Bluetooth works great too. Overall a superbly made little amplifier.

Pairs Quickly with Bluetooth

Reviewed in Australia on 27 September 2019

Colour: BlackVerified Purchase

The Douk mini amp looks solidly made and arrived with a Australian plug. Bluetooth pairing with a Samsung Galaxy Note was quick and the sound was very stable. Delivery was took a lightning 7 days.

Speakers can be connected via banana plugs or bare wires (screwed in place). In testing, it appears only one phone can be connected at a time.

The amp has plenty of power to drive old PC speakers.

New life to vintage Hifi speakers

Reviewed in Australia on 18 September 2020

Colour: BlackVerified Purchase

Not a lot to say that hasn’t already been said. I’ve only had this a few hours but the sound is fantastic on everything from Steely Dan to Bach to Kendrick Lamar. If you have eclectic taste, and want to bring an older set of speakers to life (mine were a vintage set of PYE’s) then just get one. You won’t regret it.

Busted after over a month.

Reviewed in Canada on 27 June 2020

Colour: BlackVerified Purchase

I bought this amplifier a little over a month ago and performed spectacularly with a couple of Polk Audio RTi A1 I have connected to it. Lots of power and definitely gives good soundstage no small bluetooth speaker can provide, I give it that.

I’ve been using the setup at least thrice a week via bluetooth and it’s been flawless so far until today. I turned it on as usual and suddenly there’s a cracking sound at first then a very faint output of what I’m supposed to be playing - just on the right speaker. Left speaker is flat out dead. I did the usual troubleshooting of removing and reconnecting cables, unplugging the cord from wall outlet, turning off and on the amp and even restarting the bluetooth source but to no avail.

It’s very disappointing that this amp only lasted more than a month so i’m definitely unhappy about this. My return window is already closed so I’m left for dead here with a faulty amplifier. I hope I can get a replacement as this device is really promising if and when it works.

Cutting out at modest volumes

Reviewed in Canada on 3 June 2020

Colour: BlackVerified Purchase

Right out of the box I noticed sound kept cutting out and coming back randomly. Thought it was Bluetooth connection issue so changed to line in jack from my iPod and same thing. If I play at very low volume it seems ok but as soon as you get it about 40% on the volume knob it starts cutting out. Assume it is an issue in the amplifier section. Replaced it with another amp and that works just fine. Quality control is probably the issue. Get it if you are feeling lucky.

Wow! Wish this existed years ago

Reviewed in Canada on 10 January 2020

Colour: BlackVerified Purchase

Last week I was about to toss out an old pair of Boston Acoustics speakers because the passive radiator was shot around the rubber rim, but after some thought I decided to rip out the tweeter, woofer, and crossover out the box and keep them for a "repurposing" project. The project advanced rapidly as it got under my skin and within two days I had built some much smaller bookshelf speaker boxes with a bass reflex port in back. During the finishing I realized I had no available amplifier to drive these, so a quick search on Amazon found this tiny beauty of an amp. I ordered it and it arrived next day just as I had completed the speakers and prepared the wiring to them. Within 5 minutes of arrival I was like a kid on Christmas morning trying out my new/old Boston Acoustics modified speakers. Aside from the fact that my rebuilt speakers sounded fantastically clear, I was shocked that this little amp delivered so much sound. It is really way too loud for my liking past 1/2 volume but remains undistorted. I'm now thinking of getting another one for a home theatre setup as this is so small it can fit anywhere. Bluetooth paired immediately. Bass and treble adjustments are well appreciated. I like the standard banana connectors at the back instead of poorly designed spring-clip toggle wire connections. Definitely one of my best buys on Amazon! My home office is now wired for high quality sound bluetoothed to my PC for endless hours of music while I work.

Great sound from small unit, easy to set-up

Reviewed in Canada on 21 November 2019

Colour: BlackVerified Purchase

I have had this unit a little over two weeks. I use to drive a pair of MTM speakers, each with 2- 6" woofers and a single 3" tweeter. Specs on the speakers say they can handle up to 200W at 40Hz. They're big, but this amp powers them just fine for the room they're in. Sound is crisp and clear. Bass and treble adjustments work fine. Bluetooth connection was near instantaneous.
Only downside, and it's probably related to the size of my speakers, if the bass is set too high, or if the volume is high and a song with heavy bass comes on, the sound starts going on and off. Turn the bass down a bit resolves this. Weird, but that's what I noticed. A little irritating, but there is still lots of bass there.

All in all a good unit for the price if all you want is a simple amp and not a giant receiver amp.
