Of course any educated HT enthusiast knows that the rule of thumb is to match speakers all around (timbre match) with the same brand of speakers for a more coherant sound stage and 5.1 experience. I am wondering if there is anyone unable to do this or doesn't go by this guideline for their HT/music systems. I was at a flag football teammate of mines house the other day and notice that he had mix-matched gear all around. He asked me what I thought of his "system". Of course I was polite but schooled him on what I know w/o making him feel like I was an "audio snob" Here's what he had: Mains were some Phase Tech bookshelves not sure the model. Center was a NHT Super Zero set ontop the RPTV. Surrounds were Paradigm Titans. AS you can see, not bad speakers but I dont think these have any of the same drivers or even driver types to be anything close to matching timbre..he got all these speakers from "good deals" so they came in at different times when his wife gave him the nod to buy em. (poor guy). Using a Denon 2800, it only sounded good to my ears in stereo (of course!) It goes to show you that many people out there may have the same type of unmatched 5.1 setups. Any of you with better results. Oh, he likes it that way, and that's just fine. He has to no one else afterall.
