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.

Thx

Any given receiver will run cooler with 8-ohm (or "6-ohm") speakers than
with 4-ohm. This can be important in terms of the longevity and reliability
of the receiver.

Thanks to all of you who replied to my questions.

Answering to your comments:

- almost every Blu-Ray disk has either Dolby or DTS 7.1 sound track.
This addresses issue of 7.1 source.

- I already have 5.1 HT setup at home. So upgrading to 7.1 should not
be difficult with new AV receiver and additional pair of speakers.

From now on I will be looking AV receiver that exp[lisitely made
for 4ohm speakers.

Thanks again to everybody.
