As JohnK and FordPerfect have already said, your 1400 should have no problem with 6 or even 4 ohm speakers. I have used my 2400 with the impedance set to 8 ohm to drive 4 ohm Magnepans without any problems.

If you are still uncomfortable with it, go to www.audioholics.com and do a site search with the word "impedance". Lots of other great advice on that site as well.
