Description
  • Fully Discrete NFCA for Superior Sound The TOPPING A90 Discrete features 4 NFCA-Discrete modules with 39 transistors each, ensuring high output, strong current, and low impedance for effortless headphone driving.
  • Re-Optimized Circuit for Ultra-Low NoiseThe TOPPING A70 Pros newly developed input stage boosts noise performance and input impedance (20k) for better device compatibility, while the gain architecture minimizes noise at high gain settings.
  • Ground Loop Noise Terminator Use the GND/LIFT switch to eliminate ground loop noise. Set to GND by default, switch to LIFT if noise occurs for uninterrupted audio.
  • Headphone Amp & Preamp in One Functions as both, with 20 SE and 40 balanced output impedance, ensuring compatibility with various power amps.
  • Expanded Inputs with Ext90 The A90 Discrete has XLR and RCA inputs but expands to 4 XLR and 2 RCA with the Ext90, plus a 12V Trigger for easy device sync.
  • Precision R2R Volume Control Uses relay and resistor networks for precise, durable volume control, ensuring accurate channel balance and remote convenience.
  • Volume Memory for Convenience Remembers volume settings for PRE, HPA, and PRE+HPA modes, restoring previous levels automatically for seamless use.
