The DAC Topping D70 features many refinements specific to a high-end audio product. Powerful chips, ultra-low jitter clocks, latest generation interfaces and great versatility, this converter offers exceptional audio reproduction, characterized by magnificent transparency and a beautiful sound richness while offering practical features.

DAC 2x AK4497 & Accusilicon Clocks

The AK4497 DAC chip from AKM is the brand's current flagship, allowing efficient and accurate decoding. Thus, the D70 integrates a pair of this DAC, each being associated with a channel for better separation of these. These chips allow it to reach a THD+N of -116dB and a dynamic range of 131dB. In addition, these chips support high sampling rates, allowing you to enjoy your PCM files up to 32bit 768kHz and DSD up to DSD512 Native.

These AK4497 DACs are combined with a pair of AccuSilicon 45.1584MHz and 49.1520MHz high-end femtosecond clocks. These allow a perfect synchronization of the data signals for an impressive jitter attenuation.

Connectivity & Features

With its many features and connections, the Topping D70 can be integrated into the vast majority of audio systems, offering many options for use and installation. On the input connector side, the device offers AES/EBU, Coaxial SPDIF, Toslink Optics, USB and I2S LVDS via HDMI. Note that this last input has several selectable modes, in order to adapt to your other I2S LVDS devices. The output includes balanced XLR and single-ended RCA. The D70 allows you to select the output so that you can send the audio stream only to one or both of them at once.

The D70 also acts as a preamplifier since it includes a volume controller with attenuation from -99dB to 0dB. However, this volume control function can be disabled so that the D70 can only be used as a DAC with output levels constantly at their maximums, i.e. 4Vrms for XLR output and 2Vrms for RCA output.

USB XMOS XU208 & SPDIF AK4418 Interfaces

Once again, on the side of its digital interfaces Topping chooses quality and performance by integrating high-end chips into its D70. For the USB interface, we find an XMOS XU208 chip supporting high sampling rates up to 32bit 768kHz in PCM and up to DSD512 Native. For SPDIF signals, an AK4118 chip does the job by providing the lowest jitter on the market for this type of interface. This chip is therefore used for the Optical, Coaxial and AES inputs and allows sampling rates of 24bit 192kHz to be achieved for the latter.

An incredible quality circuit

While the conversion and interface chips integrated into the D70 represent the best that is currently being done, the rest of the circuit is not to be outdone. For example, the PCB contains 4 Nichicon FW 3300µF capacitors as power reserve for the AK4497 and 8 Nichicon Muse capacitors for coupling the output signals. The output circuit is composed of a series of 3 AOP LME49720, high precision Vishay resistors and WIMA capacitors for excellent performance. The power supply circuit, on the other hand, incorporates ultra-low noise low voltage drop (LDO) linear regulators TPS7A4701 and TPS7A3301. This manufacturing quality allows the D70 to offer a breathtaking sound reproduction, with incredible precision, richness and depth.
