So, it's been a while. I ended up going with the JDS EL Amp II/DAC stack for a while. Changed my whole desk layout so I could have easy access to the volume control, and really enjoyed it.... for a while.... A friend also hooked me up with a modius and an Asgard 3 for cheap, unfortunately he needed to sell due to lack of employment. And I actually enjoyed using both stacks, aside from some small quirks with the Asgard and the Modius, everything worked great.
Then one day something popped up on my Amazon recommended deals for a really, really nice price... so I am now a proud owner of the RME ADI-2 DAC FS. I waited 3 days for it to get here, so I downloaded the manual, got familiar with the settings and layout, had the new firmware downloaded ready to go, and of course, went through these forums to see if there might be anything of interest to me regarding the unit.
Needless to say, setup took about 10-15 mins, and I am currently listening to my Sundara's as I type this, and enjoying the features I get to play with, the desk space I got back, and of course, the music. Just as an aside, according to my serial number, I have actually received the AKM 4493, and not the ESS version, RME have said there is a letter following the serial number that will indicate which unit is which, A - for 4490, B - for 4493, and C - for ESS, if anyone was curious.
