{"product_id":"jeff-rowland-coherence-one","title":"Jeff Rowland Coherence One","description":"\u003cp\u003eThis preamplifier combined technical innovation with unmatched beauty and ergonomics back in the day and is still considered highly sought after by many audiophiles. Advances in field-effect transistor technology and research into low-level signal recognition and resolution have positioned the Coherence One preamplifier as a standard by which other units will be compared. It is powered by a companion power supply that eliminates the possibility of hum field contamination in the low-level circuitry. In addition, extra care was taken with the overall power supply design, based on the understanding that an audio amplifier is simply a modulated power supply.   This unit has a built-in MM\/MC phono preamp.\u003c\/p\u003e\n\n\u003cp\u003eFrequency response: 5Hz to 160kHz Total harmonic distortion: 0.0016% Gain: 20dB (line) Signal to noise ratio: 96dB (line) Channel separation: 110dB (line) Output: 13V (Pre out Max) Dimensions: 445 x 309 x 94mm Weight: 18kg\u003c\/p\u003e","brand":"Jeff Rowland","offers":[{"title":"Default Title","offer_id":59370664493401,"sku":"2105","price":2290.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/5721\/8905\/files\/jeff-rowland-coherence-one-1.jpg?v=1789118755","url":"https:\/\/wenwaudio.com\/en-eu\/products\/jeff-rowland-coherence-one","provider":"W\u0026WAudio","version":"1.0","type":"link"}
