The SA-7S1 is Marantz's flagship SACD player, designed for two-channel music production and capable of playing CDs, CD-Rs, CD-RWs, and stereo SACDs. The SA-7S1's circuitry is housed in a double-layer, copper shielded chassis for dimensional stability and thorough isolation from external radio frequency (ERF) and electromagnetic (EM) interference. The rear panel is copper-plated steel. The SA-7S1 also features a segmented power supply that includes a high-capacity toroid transformer entirely shielded by an aluminum shorting ring and a copper-plated case, a design which helps keep magnetic radiation from affecting internal circuitry. A proprietary digital filter/DC filter/noise shaper with user-selectable options processes either PCM information from a CD or a DSD data stream from an SACD, and these circuits are controlled by a high-accuracy master clock designed for low jitter. Additionally, a Digital Isolator completely separates ground connections  between digital and analog circuitry for better isolation. Other features include two D/A converters providing 24-bit resolution for PCM and DSD signals, as well as fully balanced dual-differential circuits which benefit from multiple HDAM modules in the critical I/V and low pass filter sections, chosen for better speed and timbral accuracy. Available in a champagne gold finish.
