Software Updates for INVICTA

INVICTA has the ability to accept feature updates from Resonessence. For example, since initial release of INVICTA we have added many new capabilities, including SDXC Card reading, FLAC file types, advanced up sampling filters, and in a future release we will add DSD over USB and DSD from the SD Card.

No word yet on the exact timing of this update but Invicta owners are in for a real treat. You may want to pick up a few DSD Downloads in preparation.
