JG,
In case the comments about going against the grain with the switch setting are confusing, here is a
good explanation of why everyone is recommending that you not change the switch from the 8-ohm setting.
NOTE: Some Receivers have an impedance selector switch. DON'T USE THEM! The manufacturer puts them there for UL approvals as well as easing consumer concerns about driving low impedance loads. These switches step down voltage feed to the power sections which will limit dynamics and overall fidelity. Keep the switch set for 8 ohms regardless of the impedance of your speakers and ensure proper ventilation of the Receiver.
While it seems counterintuitive, it is in fact good advice.
