Thats true, but we are at  a point where a fast cpu, coupled with a fast 
GPU, is up to the challenge.
Back in the day, when CDs first came out, they said DACs couldn't do the 
job, and early CD technology
did lack some quality.  But today, your home theater DTS/Dolby is all 
digital. Most movies are digital from camera to
theater.  I've run my DFC system side by side with my K3, and receive is 
typically as good, or better, on the SDR.
