noise ..noise..noise..

Maybe the amps just have a little too much noise for your very efficient speaker system.
With speakers like that, you need a very quiet amplifier.
With most other speakers, the noise might be buried and you wouldn't hear it.

try turning your amp power down slightly to compensate for the higher input power and if that doesn't work try disconnecting your cable for your tv because if your ground in your home is bad your system will ground itself through the cable. I had this same issue and both of these solutions worked well for me
I hope they help you Greg

thanks guy. i try using it as a direct amp with the pre-amp-no change... try it as an int amp-no change..i try disconnect all interconnect-no change.

TWL. this am supposely 11W/chanel and it should work fine with the uno,cuz i used a 22w int with my uno and it is dead quiet.

The watts have nothing to do with how quiet an amplfier is.
Some are just noisy no matter what you do.Especially on highly sensitive speakers like yours. I would really consider a battery based amplifier for that type of speaker.
It just doesn't get much quieter than a battery based power supply.

this is to adress the statement that Gmood1 posted wattage of an amplifier does not directly affect how quiet an amplifier is but common sense tells you that if there is a slight noise (hum, buzz, ect.) at lower volume levels that when you increase the signal strength (ie. crank the volume) the signal(that buzz, hum) increases in volume. And to further elaborate on his posting amps usually are not noisy unless they are hooked up improperly, are hooked up with subpar cables and interconnects, or there are wiring issues with your place of establishment (as I stated before possibly a bad ground) A battery power source would be a way to isolate the system but there are more effective ways to do this like an A/C line conditioner. One can be picked up relatively inexpensively. I hope you get the buzz out of your system Greg
