NAIM NAP250 MOD is base on the famous NAIM NAP250, Better performance than NAIM NAP140 /200, and the price is cheaper. 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. 1: 500W high power amplifier dedicated switching power supply to ensure adequate power. 2: original power transistor D1047. 3: aluminum chassis + stainless steel switch, feel first class. 4: The machine has a perfect speaker protection circuit. 5: high-quality copper output terminals. Finished NAP250 MOD Stereo power amp X 1. Default is not include the AC input cable and other Audio cable. Default send by fast express to US, CA. Mexico and most Europe, Asian countries.
