Ldworet, I dont think I will be posting a video of a "how to build an economy QX4", but will be making them for a priveleged few for now. Who knows maybe a board and parts kit, or a complete unit might be something that could be cooking?? ;)
The way I see it is I spent almost $3K for a schematic and pictures. So I would like to show Nordost my appeciation for their business conduct and the let the audio community know just how wonderful they are.
I have seen the inside of the Symphony Pro and it is very similar to the QX4, power supply differences mostly.
