The metal walls which remain are 5\/16th of an inch thick. A top-plate of the same thickness is similarly produced, along with ½ inch thick end-plates to form the complete enclosure.

An integrated headphone system (DAC, amplifier\/energizer and open-backed headphone unit), the Sonoma M1 has been optimised from the ground up with one single minded goal. To deliver uncompromising, astonishing HiRes AudioTM performance in a truly exclusive package.\u003c\/p\u003e\n\u003ch2\u003eHPEL Transducers\u003c\/h2\u003e\n\u003cp\u003eThe ideal loudspeaker transducer would have zero mass, respond infinitely quickly to any signal, be perfectly damped, have no distortion and be perfectly linear. Until now, the technology that best exemplifies those characteristics is electrostatic. Introduced almost 60 years ago, electrostatic headphones have remained the choice of discerning listeners who demand the highest audio quality. Now, a revolutionary new electrostatic transducer, derived from the world of ultrasonics, has been developed in the UK by Warwick Acoustics. The patented High-Precision Electrostatic Laminate (HPEL) audio transducer ushers in a new paradigm in the field of electrostatic drivers, and the Sonoma M1 is the first headphone system in the world to use it.\u003c\/p\u003e\n\u003ch2\u003eInjected magnesium earcups\u003c\/h2\u003e\n\u003cp\u003eCompared to Aluminium, Magnesium is about ⅓ lighter and has superior acoustical damping. Combining excellent strength-to-weight ratio, high stiffness and outstanding EMI\/RFI shielding, Magnesium is the ideal material in which to house the HPEL transducer to ensure optimum performance. The ear-cups of the M1 are formed by precision injection moulding at very high pressure. The result is a weight of 10.7 ounces (303 grams) which contributes to outstanding headphone comfort. Only high-grade stainless steel screws and fasteners are used in the headphones for high strength and resistance to corrosion.\u003c\/p\u003e\n\u003ch2\u003eHandmade carbretta sheepskin ear-pads\u003c\/h2\u003e\n\u003cp\u003eComfort in a headphone is of paramount importance. We want you to enjoy the M1 for extended listening sessions. Producing an excellent sounding, lightweight design would all be for naught if the ear and headband pads induced any discomfort. So, to ensure maximum listening pleasure, the pads on the M1 are all handmade from top-grain Cabretta sheepskin leather. Cabretta leather is renowned for its light weight, smoothness, suppleness, and durability.\u003c\/p\u003e\n\u003cp\u003eThe leather used in the M1 is sourced from Ethiopia. The hides are then tanned by Pittards in the UK, who have been tanning leathers since 1826.

Starting with a solid billet of high purity Aluminium 6063, the material is first extruded, and then CNC-machined to produce a shallow U-shape comprising the base and side walls of the amplifier. The metal walls which remain are 5\/16th of an inch thick. A top-plate of the same thickness is similarly produced, along with ½ inch thick end-plates to form the complete enclosure. A special 3D-wave pattern is then cut into the base and top-plate by CNC-machine to facilitate heat dissipation\u003c\/p\u003e\n\u003ch2\u003eDiscrete Single-Ended Class-A Amplifier\u003c\/h2\u003e\n\u003cp\u003eLike all electrostatic transducers, the HPEL requires a high-voltage drive amplifier in order to function. In the case of the M1, the drive comes from a high-performance, single-ended, discrete FET Class-A amplifier with very low distortion and wide bandwidth which is optimally matched to the HPEL. The amplifier was designed and optimised to drive the inherent capacitive load of an electrostatic transducer, and the Class-A output stage is operated at a high bias level, and delivers a very high slew-rate. Operating at such high bias levels results in improved linearity.\u003c\/p\u003e\n\u003ch2\u003eCustom 64-bit Fixed-Point Digital Signal Processing\u003c\/h2\u003e\n\u003cp\u003eAnyone who is familiar with loudspeaker or amplifier measurements will undoubtedly have seen plots of flat frequency response from a few tens of Hz all the way up to 20+ kHz.

For the critical digital-to-analog conversion stage, we turned to an established leader in the field. ESS Technology is universally recognised as the world’s premier DAC chip manufacturer, and we have opted for their 32-bit Reference DAC. Two stereo DAC chips are used in a special mono mode to deliver a measured 129 dB signal-to-noise ratio (SNR).\u003c\/p\u003e\n\u003ch2\u003ePrecision CNC-machined aluminium case\u003c\/h2\u003e\n\u003cp\u003eIn contrast to the M1 headphones, where every effort was made to minimise weight, the M1 amplifier is a very substantial unit. Starting with a solid billet of high purity Aluminium 6063, the material is first extruded, and then CNC-machined to produce a shallow U-shape comprising the base and side walls of the amplifier. The metal walls which remain are 5\/16th of an inch thick. A top-plate of the same thickness is similarly produced, along with ½ inch thick end-plates to form the complete enclosure. A special 3D-wave pattern is then cut into the base and top-plate by CNC-machine to facilitate heat dissipation\u003c\/p\u003e\n\u003ch2\u003eDiscrete Single-Ended Class-A Amplifier\u003c\/h2\u003e\n\u003cp\u003eLike all electrostatic transducers, the HPEL requires a high-voltage drive amplifier in order to function. In the case of the M1, the drive comes from a high-performance, single-ended, discrete FET Class-A amplifier with very low distortion and wide bandwidth which is optimally matched to the HPEL.

An integrated headphone system (DAC, amplifier\/energizer and open-backed headphone unit), the Sonoma M1 has been optimised from the ground up with one single minded goal. To deliver uncompromising, astonishing HiRes AudioTM performance in a truly exclusive package.\u003c\/p\u003e\n\u003ch2\u003eHPEL Transducers\u003c\/h2\u003e\n\u003cp\u003eThe ideal loudspeaker transducer would have zero mass, respond infinitely quickly to any signal, be perfectly damped, have no distortion and be perfectly linear. Until now, the technology that best exemplifies those characteristics is electrostatic. Introduced almost 60 years ago, electrostatic headphones have remained the choice of discerning listeners who demand the highest audio quality. Now, a revolutionary new electrostatic transducer, derived from the world of ultrasonics, has been developed in the UK by Warwick Acoustics. The patented High-Precision Electrostatic Laminate (HPEL) audio transducer ushers in a new paradigm in the field of electrostatic drivers, and the Sonoma M1 is the first headphone system in the world to use it.\u003c\/p\u003e\n\u003ch2\u003eInjected magnesium earcups\u003c\/h2\u003e\n\u003cp\u003eCompared to Aluminium, Magnesium is about ⅓ lighter and has superior acoustical damping. Combining excellent strength-to-weight ratio, high stiffness and outstanding EMI\/RFI shielding, Magnesium is the ideal material in which to house the HPEL transducer to ensure optimum performance. The ear-cups of the M1 are formed by precision injection moulding at very high pressure. The result is a weight of 10.7 ounces (303 grams) which contributes to outstanding headphone comfort. Only high-grade stainless steel screws and fasteners are used in the headphones for high strength and resistance to corrosion.\u003c\/p\u003e\n\u003ch2\u003eHandmade carbretta sheepskin ear-pads\u003c\/h2\u003e\n\u003cp\u003eComfort in a headphone is of paramount importance. We want you to enjoy the M1 for extended listening sessions. Producing an excellent sounding, lightweight design would all be for naught if the ear and headband pads induced any discomfort. So, to ensure maximum listening pleasure, the pads on the M1 are all handmade from top-grain Cabretta sheepskin leather. Cabretta leather is renowned for its light weight, smoothness, suppleness, and durability.\u003c\/p\u003e\n\u003cp\u003eThe leather used in the M1 is sourced from Ethiopia. The hides are then tanned by Pittards in the UK, who have been tanning leathers since 1826.

As a result, it is impossible to use just any cable to connect amplifier to headphone. Therefore, in collaboration with Straight Wire Inc., a totally new, ground-up design was done for the M1. The goal was to meet the following criteria:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eCapacitance had to be minimised;\u003c\/li\u003e\n\u003cli\u003eMechanical noise pick up had to be minimised;\u003c\/li\u003e\n\u003cli\u003eSignal purity had to be maximised;\u003c\/li\u003e\n\u003cli\u003eThe cable had to be thin, flexible and light weight.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eDiscrete Single-Ended Class-A Amplifier\u003c\/h2\u003e\n\u003cp\u003eLike all electrostatic transducers, the HPEL requires a high-voltage drive amplifier in order to function.

A flat frequency response is the ultimate goal for those components, and is quite easily achieved in an amplifier, but more difficult to achieve in a loudspeaker, especially in a real-world listening room (as opposed to an anechoic chamber).\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eUSB Input\u003c\/th\u003e\n\u003ctd\u003eUSB 2.0, type B; accepts digital audio formats up to 32‑bit\/384 kHz PCM and DSD via DoP (DSD64\/DSD128)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDigital Coaxial Input\u003c\/th\u003e\n\u003ctd\u003eS\/PDIF; accepts digital audio formats up to 24‑bit\/192 kHz PCM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAnalog Input (High Level)\u003c\/th\u003e\n\u003ctd\u003eDual RCA; 2.1 Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAnalog Input (Low Level)\u003c\/th\u003e\n\u003ctd\u003e3.5 mm; 850 mVrms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDAC\u003c\/th\u003e\n\u003ctd\u003eDual mono, 32-bit\/384 kHz DACs with balanced outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eADC\u003c\/th\u003e\n\u003ctd\u003e32-bit\/384 kHz multi-channel ADC with balanced input buffers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDigital Signal Processing (DSP)\u003c\/th\u003e\n\u003ctd\u003e64-bit (double-precision) fixed-point processing at native sample rates\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAmplifier\/Energizer\u003c\/th\u003e\n\u003ctd\u003eDiscrete FET, single-ended, high-bias Class-A output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDistortion + Noise\u003c\/th\u003e\n\u003ctd\u003e\u0026lt; 0.05%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBandwidth\u003c\/th\u003e\n\u003ctd\u003e\u0026gt; 65 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEnclosure\u003c\/th\u003e\n\u003ctd\u003eCNC-machined 6063 aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Supply\u003c\/th\u003e\n\u003ctd\u003eExternal: 24 VDC, 60 VA, fixed frequency, class B-compliant SMPS; Internal: fully isolated, ultra-low noise linear regulation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAC Mains\u003c\/th\u003e\n\u003ctd\u003eWorld voltage compatible (90-264 V, 50-60 Hz); IEC-60320 C14, earth-grounded power cable; 1.5 meter length\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003eH x W x D: 57 mm (2.24 in) x 190 mm (7.48 in) x 290 mm (11.42 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e2.45 kg (5.40 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Warwick Acoustics","offers":[{"title":"silver","offer_id":48254984847593,"sku":"Sonoma M1 AMP Silver (OB)","price":3910.0,"currency_code":"USD","in_stock":true},{"title":"black edition","offer_id":48254984880361,"sku":"Sonoma M1 AMP Black (OB)","price":4500.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/products\/sonoma-amp-silver.jpg?v=1762461083"},{"product_id":"warwick-acoustics-aperio-goldensound-edition-electrostatic-system","title":"Warwick Acoustics APERIO GoldenSound Edition Electrostatic Reference System","description":"\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAvailable for demo at Audio46 until the end of 2025\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eAperio Headphone System GoldenSound\u003c\/h2\u003e\n\u003cp\u003eFrom the Latin meaning to uncover or open, the critically acclaimed APERIO headphone system reveals the true beauty of recorded sound.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSame excellence.
