I just finished reworking this system (again). Let me know if you have any suggestions or comments.
System edited: Haven't updated in a while, I've changed almost the whole system in the last few months. New denon AH-D7000 and Lorelei speakers most importantly. Also got a new headphone amp, tube preamp, and Audiophilleo converter
I wouldn't go for power conditioning because of the expense, but rather dedicated lines for your analog and digital. Seperating the two will give you an audible difference. Though power conditioning will raise your electric to another level, I don't know if you will (considering you're "pushing the envelope") want to spring for the $$, for what quality power conditioning will cost. I'm an Audio Magic fan. Have been extremely happy with their line, but even the Mini Stealths are perhaps a little more than you want to go for. If not, jump in. There's an Audio Magic Stealth for sale on the 'gon for a great price. You can plug your entire system into it.
