Hey thanks for the help guys. It has actually been a while since I have tried to use the 555mk2 but I did contact adcom at the time and they had mentioned about the dc offset. I did check with a multimeter at the time and was getting some offset on both channels. Adcom said if it was the same on each channel to not really worry about it. I would like to still use my adcom amp in my bedroom, if I open it up will I see leaking fluid?

Videodrome is correct, the kappa line is a difficult load on amps-the kappa 9 dips down below 1ohm! I had the adcom amp paired with an adcom 555mk2 preamp(both are 18yrs old) and the sound was awesome. Once I got into hometheater, the 2 channel setup was removed and replaced with the 990 and the parasound 1206. Again this is a great setup but the kappas need alot of current to do their thing. The 1206 has peak of 35 amps per channel and its bigger brother, the 2205 has a peak of 60. I think the extra current will give the speakers the steam they need. I am always open to others comments and opinions, so please if you have an idea about other amps or info on the adcom let me know. Thanks again, Brian
