Hi, I have some older Yamaha speakers and I was considering replacing them because I don't have a full set. I currently run the system with a Yamaha v671 reciever. I have 2 Yamaha ns-2hx bookshelves running as my fronts, a ns-c5hx as the center, a set of Bose (I know) 161's as the surround, and a certain vega subwoofer. I was trying to make a complete set by adding the 8hx's but they were a little out of reach due to cost. They are incredible speakers but since they are discontinued, I kinda screwed. Should I keep the hx's I have and add some other fronts or would I be better off replacing everything. Thanks for the help.
