Power Cables
@spipa, I just received the Synergistic Research Black PC from the Cable Company and it is amazing. If you are looking for an upgrade for your Adcom, this may be it.Deep, tight bass, excellent imaging and a soundstage that extends beyond the speak...

You could try Synergistic Research's new RED or BLACK PC. I haven't heard them yet, but they have similar attributes as their highly regarded fuses. Very affordable with a 30 day trial offer. 
Isolating Digital Noise, need help.
You're right, my tests indictate that the chassis is not grounded. He said the grounds should meet at a certain point and he will need to look at it. Also do to age it should be serviced, so I've packed it up to ship to him.Will discuss grounding ...

UPDATE...I spoke to the owner/tech of the only authorized Sunfire service center regarding the grounding design of their amps. He said in a Sunfire amplifier that the chassis, power and signal ground are connected together.  We discussed my ground... 
Speaker recommendations
An amp will seldom overpower a speaker. In fact, blown speakers or poor speaker performance is usually the result of underpowering them. More power is always a good thing.If the sound is not as bright as you would like, then it is the speaker... 
Help! My system is very bright it hurts my ear
terry, don’t you think it would be better to find the root cause of the problem, rather than apply band-aids or work-arounds?  @onhwy61, good question. @fatgosil , are you aware of these tone controls and how to use them? 
Help! My system is very bright it hurts my ear
Thanks for the reply, Al. This difference in gain shows that the OP's passive biamp is not an optimal setup. All the more reason to use one amp during this troubleshooting process as you stated earlier. 
Help! My system is very bright it hurts my ear
Do you have a source other than your CD player, such as a tuner or TT? You have a good CDP, but Amperex tubes can have an "edge" or sound bright with some CDs.Also, if the gain of the CDP is too high for the preamp, it will sound bright.@almarg,Al...

@fatgosil, there are ways to improve the acoustics of your room. Use several throw rugs in your listening area, or an oriental rug. You need wall-hangings, or better yet, some acoustic panels for sound absorption. Don't try to fill the entire room... 
Skyline Diffuser
http://redspade-audio.blogspot.com/2011/04/diffuser-panels-why-you-need-them-and.html?m=1Typically some absorbtion or simple diffusion panels are used on the wall between the speakers to improve imaging. A skyline panel in that position may break ...

I agree with losing the biamp for now; simplify your system and use one amp until you stop the offending brightness.  Then address treating your room for best sound. Can you answer these questions, please...- What are the dimensions of the room? W...

@czarivey, I also heard there was something odd about that place and that it was expensive.Rita's (Bob Carver, partner) is closed and Vintage HiFi of Pittsburgh (Carver sales and service) is out of business.Anyway, I think my amp needs a routine r...

Many thanks, guys. I'll contact Approved Audio first since they list Carver as one of their supported brands. 
Blue Circle's PLC -2 Thingee conditioner versus Transparent Audio PLC 6 conditioner???:
+1 lak. XOe is a significant upgrade. 
Blue Circle's PLC -2 Thingee conditioner versus Transparent Audio PLC 6 conditioner???:
You're most welcome, nonoise. When I got my Thingee, I plugged everything into it, including my high-current amp, due to it being called a "non-current-limiting" device. Sure, the noise-floor was lower, but there was a loss of dynamics and "air." ...
