Product Infomation  
There are a few common questions being asked about the INVICTA and this note will try to explain the philosophy behind various design aspects and answer some of them.

The INVICTA, like all complex machines of this era, consists of three essential parts: the hardware that is shipped to our customers, the firmware that can be upgraded from time to time and the software that operates the machine and provides its essential functionality.
Within these three elements is embedded our expertise – the best we know how to do from our collective experience – directed towards making an audio DAC.
 
The hardware once committed is unchangeable, and many iterations of hardware were prototyped before the final hardware of the INVICTA was decided. That hardware implements all the firmware and software we currently have to offer, but we know very well that over time we will have more software to offer.
 
Consequently, we have taken our best estimate of what the market wants, what companies like Apple and Microsoft (not to mention excellent Open Source teams) will produce, what industry insiders tell us will be the foreseeable future of a product like the INVICTA, and we have added to this hardware base all the support for these features. A fine example of this is our ability to deliver the user a choice of seven different filter types, even though this feature was not envisaged in our original design.
 
Every aspect of the INVICTA is programmable to some degree:
the IO ports meet or exceed the physical layer specifications, so that for example, the three rear BNC connectors are electrically isolated, capable of 75 ohm impedance match, two are programmable as input or output, and currently configured as two selectable SPDIF inputs.
(Because that is what our selected reviewers agreed made sense – if it turns out customers want Word Sync, Clock and Data – which we initially considered – then a simple software upgrade will create that).
Furthermore the HDMI interface allows users to display files stored on the SD card and in future it will be possible to implement I2S over HDMI, HD OSD output, even ultimately HDMI Audio input if technology moves in this direction.
 
Even though the INVICTA is a complex, highly reconfigurable product that may please your intellect, remember that this is secondary: it is first a machine to move you emotionally with superb sound.
