Hi there I have the brand new Sony STR-DA5200ES receiver and will be getting some Martin Logan Speakers. The speakers I am looking at are rated at 4 ohms and my receiver can be set at either 8 or 4 ohms. I know it all has to do with how much electrical resistance there is on the amp of the receiver. But every site I have tried to read about it they all get very technical and don't give basic answers. Well I have a few questions about this. 1. Would I actually get better performance out of the receiver and speakers if I do set it to 4 ohms. 2. What is the main advantage to setting it to 4 or 8 ohms in terms that the average person would understand. 3. A friend told me if I have 4 ohm speakers and can set my receiver also to 4 ohms that I would be able to be able to run my speakers louder and put less wear and tear on my receiver is this true? 4. Also what would be the best way to hook up a speaker than can be bi-wired in this circumstance would it be best to do 1 of the following and please explain why. single wire 4 ohms single wire 8 ohms bi-wire 4 ohms bi-wire 8 ohms Thank you to anyone who can answer any of these question and I will admit I do work in the home theater industry as an installer and I am not a moron but the whole ohms thing just confuses me.
