Just an FYI: I built a new system for a friend, and with a Gigabyte Z77 board paired with an i5-3570K, he now has a SCREAMING system that still works with his Echo Mona and Echo Layla24. Pretty amazing that these old interfaces can still be used in state-of-the-art systems, isn't it? Eat that Mac users! R

Interesting... I was thinking of retiring my Echo-Mona but maybe a system rebuild would be worth it.
 
What O/S are you running (Win 7/ Win 8) and is it 64-bit?
 

Windows 7 64-bit! The system runs great and those Mona interfaces kick ass! R
