So I bought r820s for the front to replace my eosone e400s and picking up a rc35 today. Was wondering what's a good next step, I'm running a Onkyo rz-810 receiver so I was thinking of upgrading my Klipsch sub 12. It's been ok but wasn't sure if adding something like a line conditioner mine be better to spend money on first. Eventually I want something like rp 280s for the fronts but that's down the road. Also at what point do people generally consider adding amps . I mostly just use it for home theater. Thanks in advance
