Topping D900: Flagship Discrete PSRM DAC & Preamplifier
Topping D900 is a new DAC and preamplifier for a high-end home system. The device is built on a fully discrete PSRM (Pure Reference Switching Module) architecture, developed from scratch by Topping engineers. In this system, the reference voltage is created by a passive resistive divider without noisy stabilizers, and the switching logic operates at nanosecond […] More
