$4,995 Sonoma Model One (M1) Electrostatic Headphones + DAC
High-Precision Electrostatic Laminate Transducer
The new Model One (M1) Headphone System from Sonoma Acoustics is the world's first headphone system to use the High-Precisions Electrostatic Laminate (HPEL) audio transducer developed by Warwick Audio Technologies Ltd.
This patented technology brings in a new paradigm in the field of electrostatic transducers. It offers very low moving mass for extended high frequency response (over 60 kHz) and unmatched transient response, uniform drive over the entire panel to minimize break-up modes, and light weight for improved comfort.
The simplicity of the HPEL's design ensures exceptional durability and reliability as it is produces with modern automated manufacturing techniques to ensure unprecedented consistency and matching between transducers.
Injected Magnesium Ear-Cups
Magnesium is the ideal material in which to house the HPEL to ensure optimal performance. It has excellent strength-to-weight ratio, high stiffness, superior acoustical damping and outstanding RFI/EMI shielding. The low weight also contributes to outstanding headphone comfort.
Handmade Hair Sheep Ear & Headband Pads
The ear-pads and headband are handmade from top-grain, Cabretta hair sheep leather to ensure comfort during listening sessions. This leather is known for its light weight, durability and softness.
Custom Low-Capacitance Cable
Sonoma Acoustics has been in collaboration with Straight Wire Inc. to develop a special ultra-low capacitance cable to guarantee ideal signal transfer between amplifier and headphone. This extremely flexible, low weight cable is detachable via high-precision, self-latching connectors.
Class-A Energizing Amplifier
Like all electrostatics, the HPEL requires a high-voltage drive amplifier in order to function. The supplied drive comes from an optimally matched, high-performance, discrete FET Class-A amplifier with very low distortion and wide bandwidth.
The amplifier is encased in a completely shielded, machined aluminum enclosure to ensure isolation from all interference sources, and provides USB and coax S/PDIF digital as well as RCA analog inputs.
The USB input accepts all Hi-Res Audio formats up to 32-bit/384 kHz PCM and DSD via DoP (DSD64 and DSD128), while the S/PDIF input accepts all PCM formats up to 24-bit/192 kHz.
ESS SABRE Reference DAC
ESS is universally recognized as the world's premium DAC chip manufacturer, and Sonoma Acoustics has opted for their 32-bit Reference DAC. Each stereo DAC chip is operated in mono mode to provide a measured 129 dB signal-to-noise ratio.
Custom 64-Bit Douple-Precision Fixed-Point DSP
In order to obtain the desired response at the output of the headphones, Sonoma digitally processes all signals using custom 64-bit double-precision fixed-point arithmetic. Fixed-point is known to be superior in the world of audio processing, and their 64-bit arithmetic exceeds even the performance of professional audio workstations.
AKM Premium ADC
All incoming analog signals must be converted to digital ahead of the DSP, and for this they use a multi-channel 32-bit/384 kHz AKM Premium ADC to deliver a measured signal-to-noise ratio in excess of 120 dB.
Superior USB Data Cable
With gold-plated connectors and a silver-plated data path, the supplied USB cable, co-developed with Straight Wire, is the perfect connection between your digital music source and the Sonoma M1 system.
Custom Universal Voltage PSU
Sonoma's custom-designed, universal voltage switch-mode power supply utilizes a fixed frequency design optimized for low noise within the audio bandwidth. To ensure a good connection with the amplifier unit, they use high-performance, locking DC power connectors. All audio circuitry within the amplifier is supplied by a secondary stage of ultra-low noise, high current linear regulation.
Thank You.
