Topping D50s specs

Thanks to its outstanding specs, D50s earned Hi-Res Audio Wireless certificate and supports Sony LDAC technology. Qualcomm CSR8675 chipset fitted inside D50s is a premium tier single-chip solution delivering high quality wireless audio performance. Working in Bluetooth v.5.0 it offers integrated support for aptX, aptX HD, Active Noise Cancellation and Qualcomm TrueWireless stereo as well as aptX LL, LDAC, MP3, AAC and SBC codecs and protocols. CSR8675 supports sampling rates up to 192kHz/24bit. These specs guarantee highest quality wireless audio playback currently available on the market. D50s THD+N is as low as 0.00025 percentand SIAND is 112dB.

Dual ESS ES9038Q2M SABRE DAC

The ES9028Q2M SABRE Reference DAC by ESS is a very high-performance, 32-bit, Stereo audio D/A converter designed for audiophile-grade equipment such as Topping D50s. Using the critically acclaimed ESS patented 32-bit HyperStreamDAC architecture and Time Domain Jitter Eliminator, the ES9028Q2M SABRE Reference DAC delivers a DNR of up to 129dB and THD+N of -120dB, a performance level that will satisfy the most demanding audio enthusiasts. Its 32-bit HyperStream architecture handles up to 32-bit 384kHz PCM data via I2S, DSD-22.6MHz data as well as a mono mode for highest performance applications. Both synchronous and ASRC [asynchronous sample rate conversion] modes are supported. Topping D50s uses one ES9028Q2M SABRE DAC per channel, meaning that it benefits from unprecedented dynamic range and ultra-low distortion, unmatched audio clarity free from input clock jitter and distortion free signal processing.

XMOS XU208 Paired with Custom Drivers

D50s uses XU208, a second generation USB interface from XMOS. XU208 chip is a representative of the xCORE-200 Series by XMOS and is a 32-bit mulitcore microcontroller characterized by its low latency and timing determinism. Unlike conventional microcontrollers, XU208 is cabable of exectuing multiple real-time tasks simultaneously and communicate between tasks using a high speed network. XU208 chip supports sampling rates of up to 32bit 768kHz in PCM and up to DSD512 Native. We also customized Thesycon drivers for D50s [for Windows 7 and above] to improve the support of native DSD.

High-performance Audio Op Amps

The D50s benefits from the state-of-art sound processing thanks to Texas Instruments operational amplifiers: two OPA1612 SoundPlus and one LME49720 that ensure a clear and lossless signal transmission. The OPA1612 SoundPlus are high-performance, bipolar-input audio operational amplifiers characterized by their superior sound quality, very low noise density and ultralow distortion of 0.000015% at1kHz. They offer rail-to-rail output swing to within 600 mV with a 2-Kohmload, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of +-30 mA. They also feature completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.

Well built and Easy to operate

DX3 Pro also comes with a great headphone amplifier. The output power is up to 700mWx2 at 32ohm load or 125mWx2 at 300ohm. It works for almost all headphones.
