Departing from traditional integrated DAC chips, the DX9 Discrete features Topping's proprietary PSRM (Precision Stream Reconstruction Matrix) architecture combining a 16-element-per-channel 1-bit discrete decoding system with an R2R resistor network. Housed in a curved aluminum chassis with a tempered glass top window, custom Aurora UI dual color displays, and a 6-channel NFCA headphone output stage delivering up to 10,000mW per channel, it offers extraordinary performance for demanding headphone and stereo configurations.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp;
