I bought it in the name of my wife delivered for me but i choose it myself and i received it 2 weeks ago ... As an exceptional gift for a model children delivered by Santa Claus before his heavy schedule ...😁
A headphone s.s. amplifier Fosi sk01 with three tone controls for my secondary headphone ( AKG K240 sextett), this amp is driven by tube preamplifier Douk P2 which drive also my small modified active speakers to greatness...( low cost chinese products are not all junk it seems ) .
I probably own one of the best audio system in the world in this low ridiculous price category ... Impossible ratio to beat trust me and no evident defect for this price and a total happiness , i will live with that and my main system a top one (Sansui alpha + optimized AKG K340 ) ... 😊
