Here's a confusing post for you.
I sold my 1010 and bought an 1820m.
Now that the Emu drivers are fairly stable, its cool. However, that took a while.
I did notice a "better" sound to the converters - crisper, you might say, or more natural sounding to my ear.
I actually really like the emu patchmix application - way more flexible than the Delta mixer - which is nearly useless by comparison. Also, the built-in effects in patchmix allowed me to sell my outboard reverb unit. Its good enough to send a little reverb to singers monitors during vocal takes, but not for final mixes.
All that being said, the 1820m has been discontinued.
