@oddiofyl that was it, I wasn't locking it; thanks!
@sfseay, my M3 had the MDx board in it from the factory. I find the ADI-2 to offer a little less resolution compared to the M3, and less drive and dynamics. The ADI is smooth and very easy to listen to. I found it lean sounding when I first hooked it up, but after running it 24/7 for a few days I feel like it has added a little more depth, although that might simply be related to me listening to the Topper D90 a lot recently which is very detailed and focused. I found the M3 a little thin sounding compared to my previous DAC (380DSD) so I could see some folks liking the ADI sound better if ultimate resolution and dynamics isn't their number one goal in a DAC. The ADI makes it very easy to listen to the music without having to focus on every little recording detail. On the same hand, on some high quality recordings I wish for a little more detail and jump similar to what the M3 and D90 offer.
For its 'relatively' modest asking price and throw in its many features, I think it is a great deal at 1/5 the cost of the M3. When you have settled in with it, please let me know your thoughts on it... I'm still tempted to try a M3 again but this time around get the integrated Ethernet board since I only stream; the big step up in price after hearing what is available for around $1K is making it hard on me to pull the trigger now though :)
