Pre-amp causing loud hiss from speakers

I have a BAT VK3i with Quicksilver Horn mono-blocks and Klipsch LaScala's. This setup is dead quiet, however when I recently hooked up Rogue Audio M-180 mono-blocks there was a loud hiss coming from the speakers well past the listening spot. This noise was constant even with the volume down to zero and occurred with either balanced or rca connectors.

When I took the BAT out of the equation there was now only a faint hiss coming from speakers but one had to put your ear to it to hear it. After disconnecting all components from the BAT and putting it back in - the noise returns. I tried a Conrad Johnson Classic and there was no noise.

So does anyone have any ideas as to why the BAK and Rogue Audios amps do not play nice together?

Thanks

I will experiment more with the IC's and binding posts,"

Just list your IC's. Someone here will know if they are balanced or not.

can't you just proceed with unhappy return after half-hour of listening?"

I agree. Any good dealer will try to do something for you.

The interconnects are from Transparent Audio probably about 10 years old. I really want to try to make this work before heading back to the dealer.

There is a benefit from getting all one's components from the same manufacturer....they play together well.

Well, I guess your run of the mill, 10 year old Transparent cables are probably internally balanced. Try new amps first and if they don't work out, you can always revisit the cable issue.

I suppose I could use the Conrad Johnson with the Rogue's as for whatever reason that combo producing no noise and leave the BAT's with the Quicksilvers and go back and forth as I wish....
