So I Got A Pioneer SX-218K Reciever/Surround Sound System For Christmas About 2 Years Ago And At That Time I Diddnt Care If It Was 2.1 Or 3.1 Or 4.1 Or 5.1 Or Whatever. And I Did A Google Search & I Cant Find ANY Info On It. So Is The Pioneer SX-218K Good Surround Sound For This Day In Age? Or Should I Upgrade To A 6.1 Or 7.1 Sony Etc? Thanks!
