Marantz SA-7S1 vs SA-1

Marantz SA-7S1 compare to SA-1?
anyone hear them both? especially on red book CD?
which one is more musical?

The Marantz SA1 has more bass.But the SA7-1 more reliable unit. There are all kind of problems with SA-1 .If the Optical Machanicsm go out you throw away the unit .They don't have the part any more
