Help Please With A Replacement For Old Aragon Amp.

Thanks adg, It's not on a dedicated circuit but I do have an Isotek Aquarius power component that is connected to the wall by an Audioquest Thunder cable with a 20 amp female receptacle. The Aragon is connected to one of the Isotek's  high current outlets with an Audioquest Tornado power cable.

Thanks for your reply. My Aragon was serviced recently for a runaway bias issue.  I bought the pre amp from a friend I had bought a turntable from. He had it tuned up by First Sound. I spoke to Emmanuel Go of First Sound, and he suggested some further upgrades.  Wondering hard about that.  I have spoken to an ATC dealer and he suggested I change speaker cables. They're Cardas Clear Cygnus, well thought of and not cheap. He said any "average" 12 gauge speaker cable would suit the ATC speakers better as he stated Cardas cable "has a dark sound"  Any comments?  I tried to test his theory but my cables from my second system won't allow to me to try. The Z style banana plugs won't fit in the amps binding posts.

Thanks guys, will do. Is the Isotek ok for the source components?
Due to an odd configuration of the outlets in my listening room, I'll need  to set up a quality power strip so I can have the Aragon run into the wall. I do have a Furutech eTP66. I can connect it to an Audioquest Blizzard PC and plug the Tornado PC into it.  My Tornado is only 1 meter and no way can reach the wall outlet.

Csm, was thinking that.  
Smrex, relatively new.
