Rec'vr thats 8 ohm but can handle 4ohm speaker
Just recently purchase a 4 ohm speaker on e-bay(polk lsi7 series). Not knowing the difference I was told that my lowly STR-de895 is not capable of powering this speaker. Any suggestion on a reasonable receiver (NTE $500) that will be compatible or at least be able to handle this 4ohm.
Thx. for info.

Purchase a modest priced amp. I wouldn't count on any receiver to be adiquate with most 4 ohm's. Although there may be receivers that can handle your new speakers, why bother when you can get an amp new or used for less than $500. Outlaw mono's for $400 a pair new and saw a pair of MB 100's (Nohr) used for $200 yesterday.

Give www.yawaonline.com a call and see what their price is for the NAD T743. MSRP ($699, shown on their site) is above your budget, but their pricing is usually lower than what they list for legal reasons. They are an authorized dealer. This receiver is 4 Ohm stable and will sound better than the Sony DE line.
A used amp will likely run you less, and is not a bad idea because you can still use it if/when you decide to upgrade the receiver (though I'd opt to get away from the Sony DE line).

His receiver does not have pre-outs, so a seperate amp will not work for him.
The only way to safely double your money is to fold it over once and place it back in your pocket.

A receiver isn't "8ohm" or "4ohm" but either supports those impedances or doesn't. Most modestly priced receivers can't handle 4ohm loads. If you're looking for the same functionality as your current receiver but upgraded amps and build quality I would look at some of the NAD stuff from the past couple of years used. Here's an auction for a T751 that would work very well...

I could have sworn that reciever had a switch in the back. Check again and make sure.

have you tried the speakers yet? my receiver is rated at 8 ohms, but i am running 4 ohm pairs all around: double advents across the front, double radio shack minimus-7s on the sides and rear. all speakers are rated at 8 ohms, but the individual pairs are wired in parallel, giving 4 ohms per channel. actually, the double advents are running closer to 3 ohms. the system plays perfectly. 110db peaks are no problem, except for the wife 
ag.
Enjoy the Toys!

Running 4 ohm nominal speakers on a receiver that is 8 Ohm nominal will always WORK, but it will also stress the amp considerably more than with an 8 Ohm speaker. That means less current overall available, running a much higher risk of clipping. Without sufficient power, you will reach distortion levels quickly and lose a fair amount of imaging and clarity. My receiver is rated at 120wpc and there was just a hint of compression at higher volume, so I added monoblocks (180wpc @4 Ohms) for my mains. The result was a very noticable improvement in detail and depth.
I'm surprised you haven't blown tweeters or shut down the receiver in your setup Andy, sounds very risky to me. I have done crazy things like that too in the past, but when I look back, I wonder how I never fried anything either.

Won't Sony ES receivers handle 4ohms? My 8yr old has a little set up in his room that I put together using an old Kenwood hatchback car audio full range box that is 4ohms per side, (makes for a nice compact setup under a rack for video gaming, movies, etc). Anyway, he blew up an old Tecnics "DD-ready" surround sound receiver playing AC/DC too loud, (chip off the old block). I picked up a used Sony ES reciver on ebay, and it shows no sign of stress at all. Barely gets warm, in fact.
My local A/V store was blowing out "5" series ES receivers for around $600 a couple of months ago.
