I am in the market of getting new speakers and most of the kind I like are 4 ohm. Now my reciever I have now is about 4 years old and I think it can go to 6 ohm. Its a pioneer vsx 1017... So I wanted to get the new reciever so it's up to date and able to play the new speakers I want. Now when I get the new reciever I will only be getting two speakers at first, maybe a center too, so I will have at minimum two of the 8 ohm speakers I have now, so would the new reciever destroy the 8 ohm speakers? And is it able to even play with two ohm levels because even with expensive speaker sets some of the surrounds are 6 ohm.
