Interchangeable input modules for MM, MC and DS Audio optical cartridges, 32-bit/384kHz signal processing, and both analog and digital outputs
Swiss audio manufacturer Wattson Audio has announced the commercial launch of the Madison Phono. First unveiled at HIGH END Vienna in June, the new phono stage has now entered full retail availability through authorized Wattson Audio dealers following the company’s September 10 announcement.
At the heart of the Madison Phono is an unusual hybrid architecture. Cartridge signals are amplified in the analog domain, while equalization is performed digitally. Rather than simply adding a digital output to a conventional phono stage, Wattson Audio combines cartridge-specific analog front ends, high-resolution digital EQ, an internal DAC, and both analog and digital outputs in a compact chassis.
Three Dedicated Input Architectures
The Madison Phono is available with one of three input architectures: Voltage, Current, or Optical. Instead of relying on a single universal circuit with adjustable gain and loading, each version uses an input stage designed around the electrical behavior of a particular cartridge type.
The Voltage input is intended for MM and higher-impedance MC cartridges and operates as a conventional voltage-sensing stage. It provides multiple gain and input-impedance settings for different cartridge requirements, allowing users to select the combination appropriate for the cartridge’s output level and recommended loading.
The Current input is designed for low-impedance moving-coil cartridges. It uses an active transimpedance circuit derived from technology developed by CH Precision, converting the cartridge’s current output into voltage. Wattson Audio says this approach is intended to reduce sensitivity to cable characteristics and conventional loading interactions.
The Optical version is designed specifically for DS Audio optical cartridges. It incorporates both the required transimpedance circuitry and the power supply needed by the optical cartridge system.
Each Madison Phono is supplied with one of these three input modules installed, and the module can be changed later if the owner moves to a different cartridge technology. It should therefore not be interpreted as a universal three-input phono stage capable of accepting MM, MC, and optical cartridges simultaneously without reconfiguration.
Analog Gain Followed by 32-bit/384kHz Digital EQ
The signal path also differs fundamentally from that of a conventional all-analog phono stage. The cartridge signal first passes through an analog amplification stage without phono equalization. It is then converted to digital at 32-bit/384kHz, where the playback EQ curve and filtering are applied.
The Madison Phono provides five equalization curves: RIAA, Columbia, Teldec, EMI, and Decca. Wattson Audio specifies equalization accuracy of ±0.1dB. By removing the EQ network from the analog gain stage, the company says it can simplify the analog signal path while improving the precision and repeatability of the equalization process.
The additional EQ curves are particularly relevant to collectors of older records, although they should not be treated as automatic label-specific presets. For the vast majority of modern records, RIAA remains the appropriate playback curve.
Front-panel controls provide access to EQ selection, gain, mono playback, and a subsonic filter. The mono function sums the left and right channels, while the subsonic filter attenuates frequencies below 15Hz.
Analog and Digital Outputs
The Madison Phono provides stereo RCA analog outputs alongside coaxial and optical S/PDIF digital outputs. The analog connection allows it to feed a conventional preamplifier or integrated amplifier, while the digital outputs can be connected to the Madison Streamer or to a third-party DAC.
An important distinction is the difference between the unit’s internal processing resolution and its digital output specification. A/D conversion and equalization are performed at 32-bit/384kHz, but the S/PDIF outputs operate at up to 192kHz, with a user-selectable 96kHz downsampling option. The Madison Phono therefore does not pass a native 384kHz signal directly to an external DAC.
The RCA analog outputs are not part of a pure analog bypass path either. Signals pass through the digital equalization stage before being converted back to analog by the Madison Phono’s internal DAC.
This makes Wattson Audio’s design philosophy clear: the goal is not to avoid digital conversion, but to use it deliberately to provide more precise equalization, broader cartridge compatibility, and greater flexibility in system integration.
Ethernet for Control, Not Streaming
An Ethernet connection is also provided, but its purpose should not be confused with network audio playback. The network interface is used for remote control, device management, and firmware updates.
The connection is optional for normal playback, and the Madison Phono does not function as a network streamer or transmit the vinyl signal across the network as an audio stream.
Compact Chassis, $5,495 in the US
The chassis is machined from aluminum and measures 175 × 185 × 52mm (W×D×H), with a weight of 1.7kg. Light Gray and Dark Gray finishes are available.
The Madison Phono is supplied with an external power supply and can also be paired with Wattson Audio’s optional Madison Power S power supply.
US pricing is $5,495, while European pricing is €5,240 including VAT. Availability and pricing for South Korea have not yet been confirmed.
What makes the Madison Phono notable is not simply the inclusion of digital processing in an analog source component. Its defining feature is the combination of cartridge-specific input architectures, programmable playback equalization, and the ability to feed either a conventional analog system or an external digital converter.
Whether that architecture delivers an audible advantage will ultimately require independent listening and measurement. From an engineering standpoint, however, the Madison Phono represents a distinctly modern approach to vinyl playback—one that treats analog and digital technologies not as opposing philosophies, but as complementary tools within the same signal chain.
