Denon recommends you use 8ohm speakers with your receiver but it will run 6ohm units without any problems. 4ohm speakers MAY tax the receiver to a point of overheating.

I looked at the Denon's manual and that is exactly what it says. I then looked at Dynaudio's Audience series and I think I am more confused....can someone explain the following from dynaudio's website:
Can I connect my Dynaudio speakers without problems at 4 Ohms / 8 Ohms with my amplifier?
Yes. Many loudspeakers available on the market are designated as 4 or 8 Ohms, but most exhibit a fluctuating impedance curve that swings from very high to very low levels - often dipping below Ohms.
These fluctuations and the low impedance dips burden the amplifier as it is faced with a very difficult, resistive load, which degrades the sound quality.
The impedance of a Dynaudio loudspeaker is perfectly linear, which means that the speaker provides a stable load for the amplifier to drive, while never reaching to low impedance levels. The value, for example, of a 4 Ohm impedance rating on a Dynaudio speaker is to be considered a minimum value, and one that will not swing lower.
Thus, the amplifier sees a very easy to drive, stable load, which allows the full potential of power delivery and sound quality of the amp to be realized.
