It's a big enough difference for me to spend $500 more on the CPU. I would only recommend it for those who were already in the process of building a computer may it be for games or software editing. The XTR filter offers more detail and linearity of sound. After having a chance to listen to it I wouldn't go back. That's how much I prefer it over the two stage version. Probably would spend up to $1000 just for it.
