Gsself - great looking gear list and nice room picture too. You are where I want to be - namely, using the LIO-8 with Apple Mac Mini as music server. When did you buy your Metric Halo as you list your price as $2995 and I think it's now closer to $4K . . ugh.
For a person comfortable on Windows and having never touched a Mac, have the Mac and LIO-8 got steep learning curves?
Are you using the LIO-8 for any kind of parametric eq or high-pass or low-pass filtering?
Lastly, you wouldn't be located near Toronto would you as I'd love to hear the system?
