    This is the most aamassing amplifier i have purchased so far from DX ! Its not the most powerful, but its so Tiny ! The output you can achive from this far exceeds expectation ! The sound quality is fantastic, low and high level, and a very low noise floor for a digital amp that has no output filter, i will be purchasing more !
    If you need a tiny high performance amp with mini subwoofer, look no further .
    Great product, very pleased to acquire.
  • Good class-D amp.

    -Stay lukewarm at low level (<5watt) and around 40°C for 2x15watt approximately.-No on/off "pop" at all.-Good sound quality.-Small and compact board, easy to integrate.-Great voltage range operation. -Very low humming (at least with a 24v power supply and 90db/w/1m speakers)
    I use it right now with a generic 24V/5A switched-mode power supply ,a 5€ USB sound-card and a 50Kohm logarithmic potentiometer. Sound is very good on my cheap 6Ohms Jamo S406. After a short break-in (2/3 hours) the bass are solid, treble/medium are clean. I didn't test it at high level but I think its powerful enough for a small party in the living room :)
    Definitely a good price/performance ratio. I would recommend it for someone who want a good sounding inexpensive system. Thanks DX for this very affordable chinese DIY audio board, they are good sounding and fun to play with. ps: Sorry for my mistakes, english is not my native language.
  • bought i to make small mp3 amp!

    posted by mikeyb789

    bought it to make a small mp3 speaker system. looked for other amps but couldent find one with low amp draw. to use with 12volt 4.5 amphour battery.
    wether its a small system like i made or a standalone amp you can make it happen with this amp. do not use very high tones withit as class d amps cannot amplify them properly and distort badly.
    buy it make something cool with it or use it to replace a failing amp in small stereo and will not disapointed
  • OMG It so small

    Well packed when arrived and that was the original box. and then in a bubble bag.
    When opened everything but the power supply felt substantial.
    Mine was Gold coloured way cool....
    After a quick set-up and checking of connectors the first sound I heard was so amazing... Loud or soft it seemed to handle it all. Big Bonus No Blue lights (LED's) but a nice red glow from the volume nob when powered up.
    It sounds BIG but its so tinny tiny...
    Ok the sound is well very nice not 10000's of Wats for a stage production. It powers a set of speakers a traditional 20W A/B class amp struggled to power cleanly, It just worked and provided some real kick and good clean treble.
    Put a nasty distorted signal and forget it... I wanted to review after a month of playing around with it but it really sounds too good. I have put a range of music from old 50's stuff to new stuff form 2011's and if it was a good recording it just rocked even the classical stuff I like a lot.
    Is it in the same league as my class A preamp and 200W class A/B power combo made by the legendary Perreeaux company of 20 years ago time will tell. It did the job I bought it for so well I'm gonna buy some more of them for other little projects.
    The power-supply can only supply 45W how much power gets to my speakers with out distortion or clipping I DON'T CARE so long as it sounds good.
  • Amazing for the price and the size!!

    It is Small, powerfull, with clear sound. allows to control bass and tremble and you can plug a USB reader.in the images it would seem bigger than it is. so it's smaller, more or less the size of half a 3.5" Hard Disc.
    Very useful if you have a pair of old speakers (not very powerful though) and your HI-Fi stoped working and you want to use them without needing to buy a big amplifier or a new hi-fi equipment.
    Amazing sound for this price, and good quality
