One of the great CD/SACD Players (read Absolute Sound's stellar review), the SA-7s1 is part of Marantz' Reference Line of top quality components. This 50 pound beauty sounds as great as it looks. Metal casework throughout including the drawer mechanism (no cheap plastic). The nicely finished remote is also metal rather than plastic. The player is fully balanced and plays all CD formats. There are switches for inverting phase, dc filtering, upsampling as well as an assortment of filters to tailor the sound of your CD's and SACD's. You can turn off the display to improve the sound and add an external clock if you wish. It also has a digital out function to allow you to use the unit as a transport only. The unit is three years old, I am the original owner and it has always worked flawlessly. Contact me through Audiogon or at firstname.lastname@example.org.
