I believe this should be the right place to put this, but I am not entirely sure. I have a Kenwood HTB205 system, and I want to upgrade slowly to a whole new system. I have already replaced the mains with an older Kenwood floor speaker, but would like to eventually replace those as well. My question is, if it is not feasible to replace the whole system all at once, which route should I take if I want the best immediate results that will only get better as I continue replacing things? Would a reciever be the best replacement? The mains first? Sub? I want my overall budget for the system to be $1000 at the absolute max, and this will be spread out over months and months. Any comments will be appreciated.
