noise ..noise..noise..

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

FWIW TWL and Gmood1's comments seem to be nearly on point....

However I cannot tell exactly what you is doing with this integrated unit when you say "I try using it as a direct amp.....try it as an int amp"..... Could you elaborate for me. Are you saying that you disconnected the amp section from the preamp section and drove the amp section with a source that had its own volume control?

Assuming that it is being used as it was intended, that is the pre-amplifier section connected to the amplifier section, what you are hearing is the residual noise level of the pre-amplifier section or the pre-amp section tubes. It doesn't make any difference whether or not the volume control is minimal or maximum as the VC preceeds the pre-amp output to the amp, in other words its out put is steady at all times. With very efficient speakers you will usually hear some hiss, especially when your ear is near the speaker. Power tubes generally do not hiss and the power section of the amp (or a seperate power amp) should be hiss/hum less under optimal circumstances.

If its a big deal for your sonically, you might try replacing the pre amp or driver tubes with some very quiet low noise tubes. It might help.
