I'm thinking of purchasing some Polk RT55i bookshelf speakers. These would run me around $400 plus shipping. They would replace some old Eosone RSF400 speakers. My system as it is now consists of: Onkyo 595 Polk CS400i Center Energy eXL:15 surrounds Should I upgrade the mains now to get a little bit more enjoyment out of my current system, or just start saving up for my future upgrade. This upgrade will not take place for at least a year. When it does happen I will be looking at the Polk LSi line and Swan Divas. I'll cross that bridge when I come to it. So should I shell out some money now for a quick improvement or wait for the long hall? I can't decide because I'd like some better sound now, but I want to save up for those future upgrades.
