{"product_id":"rega-aos-mc-phono-preamplifier","title":"Rega AOS MC Phono Preamplifier","description":"Specs: Dedicated MC phono stage with Class A FET circuitry, selectable gain (63.5dB \/ 69.3dB), adjustable resistive loading (70Ω, 100Ω, 150Ω, 400Ω), capacitive loading (1000pF, 4300pF), frequency response 17.5Hz–100kHz, and RIAA accuracy within ±0.2dB. Housed in a half-width aluminum chassis to shield against RFI, the Rega AOS MC brings technology from Rega's reference Aura phono stage into a compact unit. It uses low-noise FETs in a compound pair to prevent bias current from entering cartridge coils, preserving pure signal integrity. Built with temperature-compensating servo control, an all-analog signal path, and selectable auto-standby, it offers precise cartridge matching.\n\nReviews praise the Rega AOS MC for delivering reference-level sound in a compact footprint. Critics highlight its speed, cohesion, and timing, noting that it renders music tangible and present. Audio reviewers commend its agile bass response and transparent micro-detail, celebrating its ability to convey the full emotional realism of low-output cartridges.\n\nVinyl lovers wanting to extract maximum performance from an MC cartridge will find this phono preamp a transformative addition. By bringing flagship circuit topology into a flexible, easy-to-load component, it offers the quiet gain and refined resolution needed to bring complex pressings to life, making it a worthy centerpiece for any serious analog setup.","brand":"The Music Room","offers":[{"title":"Default Title","offer_id":53197750010137,"sku":"99829","price":1829.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/99829-7.jpg?v=1789598860","url":"https:\/\/tmraudio.com\/products\/rega-aos-mc-phono-preamplifier","provider":"The Music Room","version":"1.0","type":"link"}
