Jason Shepherd (verified owner) –
I purchased this Nilai amplifier to drive the front L/R speakers in my system & partner the 8 channel MA-01 I already own, which drives the 8 surround channels.
The Nilai sounds absolutely neutral, doesn’t get hot, even after hours of use & was a pleasure to assemble, everything fitted together perfectly.
The service from KJF is always first class too, I ordered this in the afternoon & it was still delivered the next day.
I highly recommend this amplifier & KJF Audio.
