I was wondering if I could get some advice with my current and hopefully future setup. Right now I am running a LSi center channel and older Bose 701/161 with a built in sub. This is all running off of an Onko 701 AVR. I want to eventually replace my speakers with the other LSi series (possibly 9's-front and dipole/bipole-rear). I was also wondering about getting an amp for this setup and whether or not my center channel woould currently sound much bettter with the added power. I was hoping to get away with only one amp due to the money issue. I will not be able to do all of it at once and was wondering what would be the best thing to start with. This is just in the makings right now and I was looking for some professional advice.
