v2500 6ohm 8ohm setting ??

[diggerdave]

I just unpacked my yammi v2500. evidently it has an 8ohm or 6ohm setting. my center, FL, and FR speakers are 8ohm my rear speakers are 6 ohms. I am thinking of leaving the setting at 8 ohms. Is this correct? should I replace my rear speakers with 8ohm speakers? How critical is this??

TIA,
dave

Feel free to use 8ohm setting.
