{"product_id":"mastersound-box-integrated-tube-amplifier-mm-phono","title":"MastersounD Box Integrated Tube Amplifier; MM Phono","description":"The MastersounD Box is a pure Class A tube integrated amplifier delivering 35 watts per channel into 4 or 8 ohms with an integrated MM phono stage. Built as the musical heart of a discerning two-channel setup, this Italian centerpiece pairs three line inputs with a line output and speaker taps. Its parallel single-ended circuit runs with zero negative feedback, driving six EL34 power tubes and two ECC802 signal tubes with automatic biasing. Hand-wound proprietary output transformers, Swiss copper-silver internal wiring, and billet aluminum knobs sit atop a 52-pound antimagnetic stainless steel chassis.\n\nReviews from Stereo Times and Zero Fidelity praise the amplifier for delivering linear speed, holographic soundstage depth, and lush vocal intimacy without syrupy coloration. Critics note that its conservative 35-watt rating commands complex orchestral dynamics and low-end grip with surprising authority. While reviewers mention that the hefty, handle-free 52-pound chassis requires careful rack placement, they widely regard its zero-feedback presentation as a benchmark in single-ended realism.\n\nBringing this handcrafted Italian engineering into your home means choosing emotional immediacy and harmonic richness over sterile power. Its self-biasing tube circuit and built-in phono stage simplify analog ownership while preserving pure Class A musicality. For listeners seeking an heirloom-grade integrated amplifier that breathes lifelike presence into every recording, it offers a rewarding foundation.","brand":"MastersounD","offers":[{"title":"Default Title","offer_id":68690960580889,"sku":"102203","price":1899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/102203-9.jpg?v=1794613796","url":"https:\/\/tmraudio.com\/products\/mastersound-box-integrated-tube-amplifier-mm-phono","provider":"The Music Room","version":"1.0","type":"link"}
