hi everyone been following the thread at AK about the new Kingko amps that the member RGA really like. he even replaced his 7k LM219ia amp for the small KA-101!!!! Kingko Audio im very interested about this amp being a avid fan of EL84 tube. Those tubes are imo very special and this amp seem to represent incredible value for money.Im concerned about the quality of the OPT used as the price seem almost too good to be true... Anyone heard those amps?
