Line Level\n\nI am using my Onkyo TXNR-906 as a pre\/pro and it only had 4\/6 ohm as a selection, 8 ohm wasn't an option. I agree that it does not matter since I am using a seperate amp. I tried to tell if there was a difference between 4\/6 ohm selection and there was no sound change. I am using a brand new Emotiva XPA-5. I have noticed a small volume impact with the Emotiva, but I thought it would have been louder and much more dynamic. I do here more detail but I expected much more. Any thoughts? \r\n\r\nIs it possible that another brand of receiver would have different or better line levels, causing the Emotiva amp to really shine?
