{"product_id":"allnic-audio-h5500-mm-mc-phono-preamplifier","title":"Allnic Audio H5500 MM\/MC Phono Preamplifier","description":"Allnic Audio H5500 features pure Class A zero-feedback circuitry, custom Permalloy-core step-up transformers, and four NOS E180CC twin triodes protected by anti-resonant chimneys. An automatic vacuum-tube voltage regulation stage utilizing 7233 and 5654 tubes ensures steady operational performance, while Mu-metal shielding isolates delicate audio signals from outside interference. Housed in an anti-vibration CNC-machined aluminum chassis, this phono preamplifier provides two moving magnet and two moving coil inputs, adjustable gain up to +32dB, and a front-panel current meter for real-time tube monitoring, creating a versatile hub capable of driving multiple tonearms with pristine analog purity.\n\nCritical consensus from professional reviewers and audiophiles highlights the H5500 for its remarkably black background, holographic soundstage, and dynamic rhythmic drive. Rather than presenting overly romantic or veiled tube sound, the preamplifier is widely praised for its deep bass authority, natural midrange texture, and transparent high frequencies. Listeners consistently commend Allnic for exemplary build quality and long-term reliability, noting that the intuitive tube meter offers peace of mind while the design delivers effortless, fatigue-free musicality across all vinyl genres.\n\nWelcoming the H5500 into a high-end audio system unlocks the full expressive potential of any turntable and cartridge combination. Its rare blend of step-up transformer versatility, quiet operation, and harmonic richness turns record playback into a vivid, lifelike performance, making it a compelling centerpiece for collectors who demand uncompromising fidelity from their vinyl libraries.","brand":"Allnic Audio","offers":[{"title":"Default Title","offer_id":67874832843033,"sku":"100414","price":3899.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/100414-6.jpg?v=1792783817","url":"https:\/\/tmraudio.com\/products\/allnic-audio-h5500-mm-mc-phono-preamplifier","provider":"The Music Room","version":"1.0","type":"link"}
