SUQIYA-Remote Integrated Amplifier Base On Niam Nap250 Amplifier + Nac152 Preamplifier 80w +80w Combined Power Amplifier

NAP250 is the high-end power stage, the original machine is priced at tens of thousands, the machine has a very beautiful sound, control, low frequency, analytical charm is very good! This replica version uses the same circuit and the same transistor as the original machine. It adopts a better layout and better grounding, so that the parameters, noise, charm, control and resolution of the board completely surpass the original machine. use NAP250 rear-end original parameter line, the power transistors uses 4 new 1% paired ON MJ15024. with absolute toxic sound The powerful transformer provides 200 watts of transient power.
NAC152 Preamp part

The circuit source of this machine is to the naim pre-stage NAC152, the line is exactly the same as the original machine; time aligned filter -> volume -> gain board; 729 time circuit with 2 levels of buffer. Original machine parameters, original line; mono mode design, physical 100% separation, left and right channels are not crosstalk, sound field positioning is very accurate! Core components: The transistor uses 2N5087/2N5089 used by the original machine; WIMA capacitor, Tan capacitor, 718 military 1% metal film resistor. Sound: The intermediate frequency is especially easy to get into the ear, high and low frequency and dynamic is very suitable! Coupling explanation about electrolytic capacitor We found that not all models of naim use tantalum capacitors for coupling. In order to find out that we have purchased a NAC112 preamplage earlier than NAC152, we chose NAC112 preamp because this preamp is electrolysis. Capacitor is coupled, not tantalum capacitor. After the pre-stage, we carefully compare it with the original NAC152 preamp. At the same time, we also invited several industry professionals to audition. After repeated audition and comparison, we finally concluded that The NAC112 with electrolytic capacitors is more warm and has a better musical taste. The NAC152 with coupling of tantalum capacitors is more straightforward and has lower sound. The sound of NAC112 is better because of the combination of NAC112 and NAC152. The circuit of the previous stage is basically the same. The biggest difference is that one tantalum capacitor is not used, so we also tried to use our electrolytic capacitors in the front stage of the NAC152 to make the coupling. The conclusion is the same as the previous two original machines. The use of electrolytic capacitors for coupling sounds is warmer and the flavor is better, so we used electrolytic electricity in this version of NAC152. Coupling, compared to everyone will definitely like the sound charm brought by the new NAC152 preamp
