The short answer is "yes." 

In the K4 it takes the form of distributed processing, including multiple high-speed FPGAs in the demodulation path, a new DSP that's twice as fast any we've used before, and virtually unlimited resources in our main processor. 

It's also a very modular radio. For example, if a higher-performance A-to-D converter becomes available in the future, we'll be able to offer an upgraded digital downconversion module.
