these cheap ass china brand amps typically range in price from 5-50 credits and none ogf them can compete with any oldscool quality stereo amp . you always get what u pay for .
some people expect to get the same audio experience with a 10 dollar ebay amp compared to a 30 kg 1xxx dollar high end machine . the typical donwsides are :
- no reserves for high level output ... 3-4 watt vs. nonsens 100-200 watt output
- distortions via power cord , esp. if ure planning to get the 12 volt from a pc power supply .
- load speaker pop in on power up
- high chance of failure within weeks , months ..
some time ago i tested 2 other dirtcheap candidates .
http://www.sanstargame.com/productsDetail.aspx?pcode=Hi-Fi%20Audio%20Stereo%20Amplifier%205this one may not be as good as the 20+ euro lepai but its more than ok considering the price .
and :
http://www.sanstargame.com/productsDetail.aspx?pcode=Amplifier%203this one fails after a few weeks and the pcb wobbled like a banana . considering the price it wasnt much of a surprise .
for hifi enthusiasts my advise would be to check the local used amp market or scout the electro garbage . i found a full working pioneer amp dumped aside the street next corner and sometimes see people trashing good ole 80 and 90 ties stuff ( made by pioneer , denon , yamaha ) in the junk containers .
i guess i give the DROK® TDA7297 a try . it also may be a good one for nonmame environments aka replacing defective amps in dedicated machines .
