NAIM NAP250 MOD is base on the famous NAIM NAP250, Better performance than NAIM NAP140 /200
NAP250 MOD using MINI circuit board design, reducing the length of PCB wiring.
While also reducing the impact of PCB wiring resistance.
PCB copper wire shorter, the smaller the resistance, the performance will be improved.
In addition NAP250 MOD version of the original modified some BUG. So that the temperature compensation tube can be installed with the high-power tube in the same radiator.
So that the NAP250 MOD can work in CLASS AB. To avoid the cross-distortion.
