Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

This is kinda of an important question, so hopefully it can be answered before the product launches. Answering something so important about the product specifications only after the drop ends is not an honest way to sell a product. Serial resistors will need a lot of clock cycles to output all the data. Parallel can output all the data in 1 cycle.
Also does this have an FGPA doing resistance correction of the ladder? Or are you relying on the resistors entirely?
The core of the conversion is a resistor ladder with 24 rungs, corresponding to the 24 bits of each sample. The entire sample is converted at once. In a sign-magnitude design like this, there are two such ladders per channel (four total in this DAC) operating simultaneously.
Here's a basic tutorial on R-2R DACs if you'd like to learn more:
