We are still working on the 2nd generation prototype. There are a lot of updates to the original design. The amp modules are higher quality, the audio interface/soundcard section is going to be much improved and we hope to have a new power section. The main things holding us up are:
- The audio interface/soundcard section still uses a FireWire (IEEE1394a) interface. Although, this still seems to be the best solution for multichannel sound, we are searching for a good multichannel USB2 solution. In either case (FireWire or USB2), we have a lot of work to do before completing the drivers and the control panel applet.
- We are still waiting for a couple of key vendors to finish the development of their high quality (audiophile grade) switch-mode power supplies (SMPS). A SMPS will be a much more practical solution for a multichannel system. Linear supplies with adequate power will be very large and heavy and we'd like to design chassis' that weigh a lot less than 40 lbs and are smaller than a 1 drawer filing cabinet.
