Thought that might grab some attention. I seem to be having a small problem with my m80's.... I think.
When I put my ear up to the tweeters on my m80's I hear a slight hissing noise coming from them. It kind of sounds like an air mattress with a very slight leak (hence the title). I put my spl meter right up to the tweeters and it does not pick up anything... so it is a very slight noise.
at first I thought that the noise was part of the recording... but it shows up as soon as I turn on my receiver.
I have to get pretty close to the speaker before I hear it...
The hissing is still audible with all of my other components turned off and unplugged.
Is this normal?
What is the cause?
Thanks guys!

It's your nice shiny new receiver Recheck all the wiring just incase there is a loose strand touching something it shouldn't be.

all the wiring looks good to me.
When you put your ear up to your tweeters is it completely silent?

This is normal, some power hiss is normal. I hear it also in my 80's.

No, I get some noise, but it's never really bothered me. It has been a minimal buzz or hum or white noise type thing. I have to put my ear right up to the tweeter to hear it, though. Virtually unnoticeable otherwise.

Phew. so you are telling me I don't need to spend $700 on a not home depot air dried maple wood power strip stand or some traids from shady maple? Seriously though, is this something a 'power conditioner' would cure? The sound is not audible from my seating area so it is not a big concern... I have to put my ear up to my M80's like they are telling my a secret. I just wonder if/how it can be eliminated and what the cause is. thanks, T

I have a tripplite power cond/surge HTPOWERBAR10 setup and it does not fix such an issue. Your mileage may vary. http://www.tripplite.com/products/product.cfm?productID=2812I asked the same question months ago when people thought I needed an exorcist in my basement as I was having weird things happen. JohnK, and others assured me this is fine. If you can't hear it unless you put your ears up to the speaker grill covers I would not sweat it. If I crank my Denon up to the MAX, with no music playing, I can barely hear the hiss/buzz from about 10" away.

T, most solid state amplifiers have an extremely low noise level which is inaudible in use, but there's always some. When I turn the receiver volume control to max and put my ear a few inches away(with no program being played, of course), there's a very faint hiss from the tweeter and hum from the midwoofers. This of course isn't normal use and isn't audible at all a few feet away anyway. So, what you've described wouldn't appear to be of any audible significance.

Enjoy the music, not the equipment.

Unless it is a lot worse than what JohnK has just described, it is a frequent thing that I usually refer to as the "space shuttle" syndrome. If lots and lots of top notch engineers cannot make a rocket that can't blow up once in a while, what is the probabily that regular engineers with create something totally perfect?
