Topping DX9 Discrete DAC and Amplifier

Overview

Discrete 1-Bit PSRM DAC Architecture

Powerful Discrete NFCA Amplifier

Key specifications

• Key Features:
• 16-Element Discrete Design: Uses a 16-element per channel PSRM (Precision Stream Reconstruction Matrix) DAC, an ultra-fast, discrete alternative to standard delta-sigma chips for exceptional linearity.
• Reference-Grade Measurements: Achieves flagship performance with a 131dB Signal-to-Noise Ratio and a Total Harmonic Distortion + Noise (THD+N) below 0.00006%.
• Ultra-Low Jitter Processing: A CPLD clock system and dual-stage jitter suppression circuit ensure signal integrity with extremely low jitter for cleaner, more stable audio.
• Six-Channel Fully Balanced Amplifier: Features a fully discrete NFCA (Nested Feedback Composite Amplifier) headphone amp with independent balanced and single-ended circuits.
• High-Output Power: Delivers up to 7,080mW per channel into a 32Ω load via balanced outputs, providing ample power for demanding headphones.
• Precision Volume Control: Uses a fully balanced hybrid relay-resistor network for precise, channel-balanced volume adjustment, even at very low levels.
• 10-Band Parametric EQ (PEQ): Includes a high-precision, software-controlled 10-band PEQ system for detailed sound signature tailoring and headphone response correction.
