I think the multi-channel is not for HT but for active crossovers.

Tranquility Bass,

I hope you'll wait for the new ADC chip. Take your time and get it right. Everyone can wait. It'll be better in the end.

I don't care for Indiegogo. They never resolve problems. Have used Kickstarter without problems though. I like the idea of a group buy and save the fees.

2nd on group buy. Save the fees.

I doubt kickstarter will broaden your exposure to achieve more sales. After all the best suited target (diy community + many manufacturers) does visit diyaudio.com on a regular basis. In my opinion this is where the magic happens.

Reaching the rest of the manufacturers will definitely not be achieved by kickstarter.

Cant wait for the GB list to open! I hope the project doesn't exceed 2k USD tho..

Will it be possible to implement a loudness control for the DSP?

The joy is that the fir is low latency fir.
This will be some soundprocessor with the highend DSP inside. Power to the user!

Default Audioweaver would be an ideal match

Audioweaver seems to be a great solution to make this kit flexible for all sorts of uses, but I am not sure if Audioweaver use is constrained by the developer in any way. I gather the use of this software would not be marketed or sold with the unit?

Just found this thread while looking for a winter project. I LIKE IT!

Tranquility Bass,

Have you considered design/construction options to reduce the number of PCBs?
?? Second release after debug and user feedback ??

I was looking at the Gustard X20 8 channel dac packaging which appears to have:
-large analog board with both analog RCA and XLR inputs, DAC chip, and analog power supply regulators;
----the PCB layout can solder down either RCA or XLR output jacks. (not both)
-a medium size daughter PCB with XMOS chip and rear USB socket plugs into the analog PCB;
----a digital ribbon cable connects USB data to the digital PCB
-large digital board with digital inputs, USB, and digital power regulator;
----a coaxial cable connects the digital data to the analog DAC PCB
-front panel LCD PCB
-front panel input selector PCB
-two power transformers are in a separate chamber.
