From a DIY newbie: I am very interested in a DIY project to replace existing speakers (maybe a 2nd room HT). I currently have: Infinity Entra One's for front and back Entra Center 2 Entra Sub One I would love to replace or build a new HT setup if I could improve soundstage and clarity via higher-end components and design? Some of the designs I have seen appear to meet the "wife" criteria for appearance? I have been looking at Parts express. Their prices seem reasonable? How would I begin to choose high-end components outside of price or mimicing someone else's project? TIA, Dan.
