Soulnote Z-3 Network Transport

Flagship Network Transport developed to maximize ability of ZERO LINK by eliminating any bottlenecks at the development stage.


ZERO LINK drastically reduces the work of the D/A converter and completely eliminates the use of asynchronous components in the D/A converter housing. In the Z-3, ZERO LINK replaces every asynchronous component to transmit only signals polished beautifully by the clock to the D/A converter. The resulting sound quality is an unprecedented leap forward in the sonic universe. This solution surpasses the highest levels of analog playback.

SFP port

By incorporating an optical link module, this opens up the door to optical cable connections. And the use of an SFP RJ45 module allows for compatibility with regular LAN cable connections. The optical link module, RJ45 module, optical cables, and LAN cables are not included with the Z-3.

SC Cut ultra low phase noise OCXO

An SC Cut OXCO is installed in the dedicated SFP circuit clock. Although it is an asynchronous component, every effort was made to counteract its effects by maximizing the clock quality. When ZERO LINK is connected, the high-quality D/A converter master clock transmitted by ZERO LINK is used in the I2S generation circuit and Non-PLL Sync is applied.

A dedication to non-rigid housing

Beyond the plate, we went above and beyond to create a non-rigid housing, including the AC inlet, I/O terminals, circuit boards, and circuit board chassis. We applied the full breadth of SOULNOTE expertise to components like titanium washers, spike placement directly under the transformers, and more. The air volume presented by the relatively large housing contributes to an unprecedentedly vast soundscape.

Ultra-powerful non-NFB discrete power supply

Ultra-powerful non-NFB discrete power supply

The Z-3 uses the same digital high-reguration transformer as D-3. An unprecedented 260 VA large-capacity transformer is used to create four non-NFB discrete power supply circuits separated from each circuit winding. It uses a total of 16 ultra high-speed SiC rectifier diodes and 70 low-magnification electrolytic condensers. This provides endless expressive power with overflowing clarity and directness.

Power Design by Soulnote Z–3

The current line-up Soulnote is based on new design concept.

A Variety of Application

The Z-3 can be used in the following three ways:

1. As a ZERO LINK network player (LAN input – ZERO LINK output)

You can create the ultimate separate network player by inserting an optical link module or RJ45 module into the SFP port and using it as a LAN input, then using a ZERO LINK connection with the D-3 or S-3 ver. 2. This connection method will create the highest quality sound.

* LAN input is compatible with DLNA, OpenHome, and diretta (LAN DAC).

* diretta input is only possible when connecting with diretta compatible devices.

2. As a ZERO LINK bridge (USB input – ZERO LINK output)

By using the USB input to connect to your computer or music server, you can use it as a ZERO LINK bridge with output from the ZERO LINK. High-quality ZERO LINK sound can be easily obtained by using the Z-3 in the same way as a general USB DAC.

* The USB input is compatible with Bulk Pet and JPLAY.

3. As a network transport (LAN input – USB output)

You can use it as a high-definition network player by connecting it to your USB DAC.

* USB input – USB output is not possible.
