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. 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. 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":47692172361961,"sku":"Bravura SILVER Headphone \u0026 Sonoma M1 Amp (OB)","price":5945.75,"currency_code":"USD","in_stock":true},{"title":"Black Edition","offer_id":47692172394729,"sku":"Bravura BLACK Headphone \u0026 Sonoma M1 Amp (OB)","price":7015.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/products\/Silver-BRAVURA-M1-System_1200x1242jpg.jpg?v=1762461104","url":"https:\/\/audio46.mom\/products\/warwick-acoustics-bravura-electrostatic-system-open-box","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
