Hello,
I looked at the specs for the 6240 and it certainly is full featured. The one thing I was not thrilled about is the receivers weight, 18 pounds. When a receiver weighs that little, it brings into question the power supply and the amount of filter capacitance.

When a receiver has a relatively small power supply, continuous high volume listening can be problematic. Much of this depends on the size of your room, the efficiency of your speakers, and preferred listening volume.

The good thing is you bought it at Costco so if it does not meet your needs, there will not be an issue in returning it. I would run it through its paces and see if it meets your needs.

Polk Audio, while quality speakers, are not super efficient. That is they require a bit of current to sound their best and play loud. Now, if you were running Klipsch's which are ultra efficient, this would not even be a concern.
Cheers,
JJ

Hello,
I definitely agree about the 706. Sadly, the vast majority of AV Receivers sold at Big Box Stores have wildly overrated power specifications. A good example of this is Pioneer's VSX-1019. I believe it is rated at 100 watts per channel. When tested by Home Theater Magazine, it output around 30 watts per channels when all channels were driven.

Sadly, this is more the norm than the exception. An excellent indicator is the weight of the receiver. Unless a Class D or similar digital amp design, a 25 pound AVR is simply not going to come close to meeting its rated power. One of the things I love about Onkyo's upper range is that they actually output over 100 WPC all channels driven.
Cheers,
JJ
