The Musica and the Symphony are identical other than their HD size. Since both units have 2 USB ports and now allow your choice of outboard HD's (or PC) the Symphony seems the better deal to my thinking.
The Opus has 24 bit dac chips and a redesigned analog output stage which does away with the three 2134 opamps that are in the other units. That's about all I can contribute...
