Ok, we're getting a little ot from pics of home studios, but here we go...
The actual AD/DA converter chip in the Emu's & MOTU's is the same as the high end PT interface, so they're not lying.
On the otherhand they're not telling you that their analog circuitry and clocking is to put it bluntly, crap. AD/DA converter chips are pretty cheap, but good clocking and prisine analog design is not.
Now, the digi 192 interface, whilst very good is pretty expensive for what it actually is.
There are people out there who will take a stock motu interface, and graft in some improved electronics and a much better clocking. The difference is like a summer's day to a winter' night. The motu clock as standard has a jitter around 120uS, post mod that's reduced to under 10uS, which is seriously high end territory.
