Just bought the VC1000 as my first entry into Dual BA territory, and it is a great sounding piece of kit. Depending on the tips used it can be quite bright and cold, or with my Klipsch S4 oval tips with very narrow bore, a bit fuller, not to GR07 levels but not too far off.
Great detailing and cold, crisp, prickly treble, snappy dynamics and well-extended, tight bass. Very good decay aswell, really picks apart the midrange of songs, snare drums attack well and disappear very quickly aswell, nothing really smears one bit. Very tight and fast. For $100 I'm very happy.
EDIT: If you have them, definitely try the Oval Klipsch tips instead of the Sony hybrids. The hybrids for me give a peak in the upper treble which stands out noticeably. The Klipsch, despite having a very small soundhole, preserves the dynamics well, keeps the lower treble crisp and snappy, but also gives the treble a very even extension. Loving this sound, going back and forth between this setup and the GR07 with wide bore tips, they really complement each other well. The GR07 is like a more brutal, grandiose big brother.
