Feedback from Dealer:

The specifications are the same and the circuit designs are almost identical.

There are quite a few differences in the choice of components used. The S02 uses higher quality components throughout when compared with the S03. The S03 is considered a cut-down version of the S02 as it is the same design but using more affordable components. The binding posts and connectors on the S02 are better quality and the chassis of the S02 features a larger power button with dimmable led illumination similar to the Grandioso products.

This results in the S02 performing better than the S03. It is more musical, has greater detail and is a tonally richer sound.

Same design, same internal components, but chassis and binding posts allow it to perform better and have a better sound @ a price of 35% more
