How's about a huge bump, but seriously, I want some new updated bookshelf speakers, and wanting to have them join my bose 201 8 ohm pair(which I love) I also have a pair of less expensive outdoor speakers under our carport for like grilling out, etc. which are 4 ohm (but rarely have them on at the same time as my inside speakers, and my research includes maybe using a speaker switch with ohm protection feature which says will protect the power source (reciever), in case all were used at the same time, the new speakers I'm looking at are 8 ohm. Ant opinions are welcome.
