Updating my receiver. What should I check to know if my current speakers & subwoofer will work?

I could help you out with this question as it's right down my alley. I would need a bit more info. Is it possible to get the make and model of your speakers and a budget to see what kind of receiver I can find for you.

Make sure the speakers' impedance match the

new receiver. If your speakers are rated at 6-8

Ohms, you're ok, but if your speakers are rated

at 4 Ohms, then this narrows your choices in a

receiver considerably.

Regarding power, unless your speakers are

rated to handle 50 watts max or less, you will

be fine unless you like to crank your system...

My recommendations for a receiver are Onkyo

or Pioneer Elite, or step up to Arcam which is

quite a bit more expensive and harder to find.

any specs, really should work, since the only difference would be the amps, or power as you described it. That won't be much of a limiting factor, just that you wouldn't turn the volume all the way up.

The other spec is that if it is a 1000 watt reciever, and seven speakers, then your speakers only need to be able to handle >142 watts.
