At the studio today i decided to do an experiment to check how much a source is degraded upon continuous ad/da conversion. I took a sample of work i had and went out via the Digi 192's DA and back in through its AD's. On my first trial i sample aligned up the original and then converted to see if i could identify differences in the wave and i was just shocked to see how on some transients there were immense differences. I flipped the phase to see how much they would cancel and obviously the difference was quite noticable . I then decided to keep on reconverting and on each step i could not believe how much the wave was changing when you zoomed down to sample level. What a shock this was!!! I expected change but not this obvious. On latter conversion stages audible differences became much more noticable that even a client started to recognise.

I then decided to change to my lavry blues to see how much difference this made. The difference was there but not as huge as the 192's but nevertheless it was audibly obvious after a few re-conversions.I started to think how much this degradation must affect mixing during a typical project that uses outboard. What a bummer! Just wanted to see any opinions or other experiences on this matter....
