Its Class A circuit — the same DNA as the mono MPA-4 — runs warm and unhurried, rendering transients with authority rather than aggression. Where some solid-state amps impose a clinical edge on the midrange, the SPA-4 stays remarkably composed, coaxing texture from strings and breath from vocals. The fully balanced topology adds a low-noise foundation that lets the quieter passages emerge intact. Control is real here, not euphonic softening — bass lines stay articulate even as the soundstage opens wide.\u003c\/p\u003e","brand":"Sugden","offers":[{"title":"Default Title","offer_id":68438307963101,"sku":null,"price":7250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0478\/4884\/9576\/files\/Sugden_MasterclassSPA4_Front_001_5x4_a0b3f21b-8a58-475e-af4c-a875b86356b6.jpg?v=1793919039","url":"https:\/\/auralhifi.com\/products\/sugden-masterclass-spa-4-new-solid-state-stereo-power-amplifier-75wpc","provider":"Aural HiFi","version":"1.0","type":"link"}
