{"product_id":"ma2375-vacuum-tube-integrated-amplifier","title":"MA2375 Vacuum Tube Integrated Amplifier","description":"\u003cp\u003eMcIntosh returns to vacuum tube integrated amplification with the MA2375, an all-analog design that unites a tube preamplifier and tube power amplifier on a single polished stainless-steel chassis. Four KT88 output tubes and a complement of 12AT7 and 12AX7A small-signal tubes deliver 75 watts per channel through the company’s Unity Coupled Circuit Output Transformers, preserving the rich, continuous harmonic texture that defines classic tube performance while providing the load tolerance to drive virtually any loudspeaker with composure.\u003c\/p\u003e\u003cp\u003eThoughtful engineering extends well beyond the signal path. Power Guard Screen Grid Sensor technology continuously monitors output-tube current and gently reins in the input signal when necessary, protecting the KT88s without audible artifacts, while Sentry Monitor provides fuse-less short-circuit protection. A configurable phono stage accommodates both moving-magnet and moving-coil cartridges with adjustable gain, capacitance, and resistance loading, and the High Drive headphone amplifier with Headphone Crossfeed Director lends spatial dimensionality to private listening. A five-band analog equalizer, dual blue watt meters, and a full suite of analog inputs—including balanced connections and a subwoofer output—make the MA2375 a versatile, enduring centerpiece for a music-first system.\u003c\/p\u003e\n\u003ctable class=\"pu-table\" style=\"width:100%;border-collapse:separate;border-spacing:0;border:0;box-shadow:none;outline:none;background:none;table-layout:fixed;margin:0\"\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd style=\"border:0;padding:0\"\u003e\n\u003ch3 style=\"margin:1.25em 0 0.5em\"\u003e\n\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewbox=\"0 0 24 24\" width=\"18\" height=\"18\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.75\" stroke-linecap=\"round\" stroke-linejoin=\"round\" style=\"display:inline-block;width:1.1em;height:1.1em;vertical-align:-0.18em;margin-right:0.45em\" aria-hidden=\"true\"\u003e\u003cpath d=\"M4 7h3a1 1 0 0 0 1 -1v-1a2 2 0 0 1 4 0v1a1 1 0 0 0 1 1h3a1 1 0 0 1 1 1v3a1 1 0 0 0 1 1h1a2 2 0 0 1 0 4h-1a1 1 0 0 0 -1 1v3a1 1 0 0 1 -1 1h-3a1 1 0 0 1 -1 -1v-1a2 2 0 0 0 -4 0v1a1 1 0 0 1 -1 1h-3a1 1 0 0 1 -1 -1v-3a1 1 0 0 1 1 -1h1a2 2 0 0 0 0 -4h-1a1 1 0 0 1 -1 -1v-3a1 1 0 0 1 1 -1\"\u003e\u003c\/path\u003e\u003c\/svg\u003eCompatibility\u003c\/h3\u003e\nThe MA2375 offers an array of analog inputs, including two balanced and three unbalanced connections, to connect music streamers with analog outputs, CD players, tuners, and D\/A converters. Connecting a turntable is an easy task via the configurable phono input that can accommodate both Moving Coil and Moving Magnet cartridges. The phono stage includes adjustable Gain, Capacitance, Resistance Loading, and RIAA equalization for optimal vinyl playback. A subwoofer output enables the addition of a powered subwoofer to extend low-frequency performance. Gold-plated Solid Cinch™ speaker binding posts ensure a secure and corrosion-resistant connection for speaker cables, while an unbalanced preamp output supports the addition of a second amplifier in advanced multi-zone audio systems.\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ctable class=\"pu-table\" style=\"width:100%;border-collapse:separate;border-spacing:0;border:0;box-shadow:none;outline:none;background:none;table-layout:fixed;margin:0\"\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd style=\"border:0;padding:0\"\u003e\n\u003ch3 style=\"margin:1.25em 0 0.5em\"\u003e\n\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewbox=\"0 0 24 24\" width=\"18\" height=\"18\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.75\" stroke-linecap=\"round\" stroke-linejoin=\"round\" style=\"display:inline-block;width:1.1em;height:1.1em;vertical-align:-0.18em;margin-right:0.45em\" aria-hidden=\"true\"\u003e\u003cpath d=\"M4 17v2a2 2 0 0 0 2 2h12a2 2 0 0 0 2 -2v-2\"\u003e\u003c\/path\u003e\u003cpath d=\"M7 11l5 5l5 -5\"\u003e\u003c\/path\u003e\u003cpath d=\"M12 4l0 12\"\u003e\u003c\/path\u003e\u003c\/svg\u003eDownloads\u003c\/h3\u003e\n\u003cul\u003e\u003cli style=\"margin:0 0 0.35em\"\u003e\u003ca href=\"https:\/\/pdf-upload.local\/MA2375%20Brochure%2000-2.pdf?storage=10594%2F3f688363-3af9-4ce7-9f13-aedbe5bf65a8.pdf\" target=\"_blank\" rel=\"noopener nofollow\"\u003eMA2375 Brochure\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e","brand":"McIntosh Labs","offers":[{"title":"Default Title","offer_id":43182957887586,"sku":null,"price":18000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2475\/2780\/files\/mcintosh-ma-2375-tube-integrated.png?v=1786069898","url":"https:\/\/pearlaudio.com\/products\/ma2375-vacuum-tube-integrated-amplifier","provider":"Pearl Audio","version":"1.0","type":"link"}
