I am upgrading my system from a RCA HTIB. I am going with HK325 (569 CC) (is this enough receiver or do i need to step up to the 525, my room is about 12x15) but I need to add new front speakers and a sub. I have about 400 for the front speakers and 200 for a sub. I don't go for a lot a of bass but my current nonpowered sub is pretty nonexistent. I have looked at Athena AS-F1 (399/pair at BB)and Infinity Primus 250 (399/pair at CC. For subs I have looked at Sony SAWM500 (199 at BB). My plan is to use my current fronts and surrounds as part of my surround for 7.1 and upgrade as I collect some more cash. Any suggestions on the speakers I have looked at or any other speakers in my pricerange or atleast somewhere to get better prices. Another question- my original plan was to start by buying bookshelf speakers to use for my fronts and then later move them to surrounds when i upgraded to floors but the salesman at CC said that I could blow them out using the HK. Any truth to this.
