DAC with programmable chip(s)

Your looking for a DAC like the PS Audio Direct Stream, look for DAC's with FPGA. JUst FYI, I went with a FPGA DAC since it can be upgraded for many years as the designer works to improve it.

Thanks guys for your replies...YES, an FPGA DAC was exactly what I was reading about.   Given the ever-evolving digital space, this concept made (makes) sense to me -- as long as the engineer/designer and the company are long-term players in the industry, else those periodic software upgrades/updates cease to come.   Maybe not that big a deal unless a new digital format comes about or something similar.    I'm going to check out the 2 videos (above) next.

is the PS Audio Direct Stream the most common example of an FPGA DAC ?

 Thanks, Jim
