Powered by an outboard linear power supply, it uses two 12AT7 and two 12SN7 (or 6SN7) tubes without output transformers for quick transients and cooler operation. Features include a 100-step relay attenuator with Vishay Dale resistors, LED display, balance control, home theater bypass, three RCA inputs, two RCA preamp outputs, a 1\/4\" headphone jack, speaker terminals, and remote control.\n\nReviewers praise the MZ3 for its dead-silent background, holographic soundstage, and transparent playback. Critics highlight how it blends the natural warmth and liquidity of tubes with the tight bass, speed, and precision of solid-state gear. Audio enthusiasts applaud its tactile relay attenuator, preamplifier flexibility, and ability to extract effortless dynamic realism without harshness or tube bloat.\n\nFor audio enthusiasts seeking an end-game component to drive high-performance headphones or serve as a reference preamp, the MZ3 is a transformative centerpiece. David Berning's ZOTL circuit eliminates tube maintenance hassles while revealing stunning musical detail. Adding this level of dual-chassis engineering to your signal chain elevates everyday listening into an intimate, live-sounding experience.","brand":"The Music Room","offers":[{"title":"Default Title","offer_id":53133902446873,"sku":"98841","price":2599.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/98841-6.jpg?v=1789092362","url":"https:\/\/tmraudio.com\/products\/linear-tube-audio-microzotl-mz3-dual-chassis-tube-headphone-amplifier","provider":"The Music Room","version":"1.0","type":"link"}
