I think the Kickstarter scenario is a good way to get this going.
However, $1,500 is above the price that I can afford to spend right now. At that price, I would want to hear it first to make sure I can hear a difference.
My other concern is the battery. I know it is included because it helps with the sonic qualities, but what happens down the road when it needs replacing. Do we know that replacements will be available? If for some reason a suitable replacement can't be found for whatever reason, could the DAC run without a battery installed? I apologize if any of those battery questions have been previously answered. I must have missed them.
