I have a surround 5.1 setup consisting of 4ohm speakers. Now I need to
upgrade to 7.1. So I am on the market for new 7.1 AV receiver with
full alphabet soup of sound protocols.
I pretty much narrowed on Denon, Marantz and Integra brands.

In relations with this I have two questions:

1. Looking in specs of new receivers I noticed that they quote their
power ratings for 8ohms without mentioning 4ohms without mention if I
can plug in 4ohms speakers. So is it safe to assume that modern AV
solid state receiver can handle 4ohm?

2. I need to buy new pair of surrounds. Should they be too 4ohms. Can
I mix 4ohms and 8 ohms?

I would appreciate any technical advise on this matter. You can send
responses directly to my e-mail address.

IIRC, Impedance should be equal or greater if you're going to drive
the system. Presumably an 8 ohm 7.1 system will be wanting at least
that much per channel...you can always add a 4 ohm resistor to each 4
ohm speaker to match the requisite resistance...or double the number
of speakers (chain them) on each channel...assuming you buy two new 8
ohms, you'll need 5 more 4 ohm speakers and one more 4 ohm sub to
double up...uhm...I think that'll make you a 12.2 system...ready for
the future ;-)
