i currently have a 811s pioneer that I have paired with some mediocre 3-way sony speakers. I want to get the ascends cbm 170 (l/r) and 340(c). I don't plan on upgrading my receiver in the next year because I bought it a few months ago. Will I be doing myself any justice pairing this receiver with these speakers? Should I just wait down to road to purchase the speakers when I'm ready to get a new receiver?
