Cary SLI-80 with 4-ohm setting


Can I "break the rules" and use my Cary SLI-80 with a 4-ohm setting with 8-ohm Silverline Sonata-III speakers?

I tried to set the impedance at 4 ohms and found the sound to be more relaxed than with the 8 ohm setting, though with muddier bass.

I will appreciate any comments and opinions of Cary SLI-80 owners who had similar experience.
