Customer Reviews
A mighty product! I read about JLH 1969 Class A amp and it seems like Nobsound NS-02G PRO is a modern implementation of it. I was skeptical at first and now I am a big fan. I don't usually write reviews and here I am to praise this implementation and how awesome it sounds in my desktop setup. I have paired this with a pair of Klipsch RP-600M II and a REL sub with Apple music streaming. It's rich, warm and deep, there is some punchiness to it I was not expecting. I can hear every note. It's extremely detailed. I have several Douk Audio products at home and have used them mostly as ancillary, this Nobsound NS-02G PRO is an anchor on my desktop now. Douk Audio and Nobsound hats off to you guys doing such an awesome job on this. You nailed it. I will try more of your products now.
Very natural sounding amplifier with a jet black background and plenty of detail. Matches well with my LS3/5a. Wouldn't hesitate to recommend at this price! Thanks Douk Audio.
