Those of us who have these superb machines know how good they truly are. Genesis, I agree that they keep getting better. I'm probably at around 1000-1500 hrs and it keeps getting better, more resolving, more timbral accuracy, instrument and vocal location, etc.My DA2i now has over 5000+ hours. Sounds crazy… believe it or not but around 4000+ hours everything just snapped in. If you thought your units sounds great now what till it hits 4000 hour milestone.
