Hi OCAU I'm coming from an epic Emotiva + Adelaide Speakers (Timberwolfs) HTPC 2 channel setup. This came on OCAU recommendations and I couldn't be happier. Since deploying this, I realize I spend a lot of my time on my PC and my crappy Logitechs need to go. Now I'm looking to upgrade my home office PC to a proper Sound card, Amp and bookshelf speakers. Any improvements/suggestions to the below? $190 - Xonar Essence STX $220 - Emotiva Mini-X a-100 $595 - Adelaide Speakers Firesprite 502SV Total: $1005 (+ shipping) Thanks!
