Big‑system muscle in a half‑size chassis.
The Rialto 400 packs a 100 W‑per‑channel Class AB amp, a Wolfson® hi‑fi DAC, and Audiocontrol’s AccuBASS® processing into a case small enough to hide behind a bookshelf speaker. Whether you’re juicing a pair of towers, driving outdoor speakers, or giving your Sonos/HEOS zone a serious upgrade, Rialto delivers velvet mids, iron‑fisted bass, and 24‑bit/192 kHz clarity—all backed by Skadi’s 1‑year warranty.

Key reasons you’ll love it

  • Wolfson WM8740 DAC handles 16/24‑bit PCM up to 192 kHz for ultra‑low noise. AudioControl Pro

  • Dedicated subwoofer pre‑out plus AccuBASS® to restore low‑end punch at low volume. AudioControl Pro

  • Tiny footprint – only 8.5 ″ W × 5.4 ″ D × 2.9 ″ H, weighs 2.7 kg. AudioControl Pro

  • Built in the USA & designed for 24/7 custom‑install reliability; 5‑year manufacturer warranty (Skadi adds 1 year on refurbished units). AudioControl Pro
