Marantz PM-15S1 2007 Reference Catalog - Page 8

Source Components Since the beginning of Compact Disc, Marantz has been a leader in digital source components. Marantz introduced the very first CD player ever, and has continued to be the benchmark against which all others are measured. Marantz was also at the forefront in Super Audio Compact Disc development and continues to support this top shelf format. All Marantz Reference disc players support 2 channel SACD as well as standard CD. Often noted for bringing out more in standard CDs, helping them sound more like SACDs, Marantz has meticulously focused on this segment for years and has developed numerous innovations and refinements. From the quality of our custom designed and built transports, to our use of grossly oversized power supplies, to our copper chassis and shielding, the Reference line of SACD players are truly second to none. Reference SACD Players incorporate the following: HDAM-High Definition Amplifier Modules-HDAMS take the place of the integrated circuit chip or op amp gain stages that many "high end" amplifiers implement. Replacing all these devices in the pre driver stages of our amplifiers with hand selected discrete components are a primary factor in our success in amplifier technology, and the heart of "The Marantz Sound" To ensure optimum sound with the least amount of noise, Marantz uses magnecoupling to keep the analog and digital sections of the SA-7S1 completely isolated, without the use of jitter causing opticouplers. Toroidal Power Supplies Nearly all Marantz Reference source components use over sized copper encased Toroidal power supplies. This allows tremendous amounts of current capabilities with minimal noise and outstanding stability
