SI-300.2d versus DMS-300A
Two integrated amplifiers with digital section: high power without streaming versus complete DMS platform.
Both feature in integrated amplifiers and digital sources, yet they address opposing needs: the SI-300.2d prioritises power and home cinema bypass; the DMS-300A focuses on network playback.
The SI-300.2d is not a network player: Ethernet/Wi-Fi is solely for app control. The DMS-300A includes full Connect services.
