PS Audio AC-5 question

I recently bought PS Audio AC-5 power cord for my Parasound HCA-1205A amp. My pre is Anthem AVM-20 with Shunyata Diamondback power cord. My speakers are Paradigm Studio 60 v.3. When I changed the power cord of the amp from stock cable, I found that the overall sound is more forward than I would like. Also the top end has opened up, but I feel it to be a bit harsh - to the face. Not sure what is the issue. Is the PS Audio AC-5 a worng choice to Parasound amp?.
i agree. currently have ac10's and ac5's in my system and all required a long break in. mine didn't get sorted out until 200+ hours and sounded even better after 400 hours. give them a chance to loosen up and they'll do a wonderful job.
Thanks jdub and levy. After reading ur comments, i think I made a right decison in picking ac-5. Long wait ahead of me for cable break in. Also, i swapped out shunyata diamondback from my avm-20 to ac-5 cable.I loved the way the preamp sounded. So i have started to think diamondback to be a weak link. I have a good deal on audience powerchord(old version) and Shunyata Taipan Alpha(old version), will any of these better diamondback on preamp or power amp (ac-5 and powerchord/taipan alpha combo).
If your budget allows and If it where me, I would get another AC-5, works better in tandum ,in fact I'm going to sell my Statement SC in favor of an AC-5 or AC-12 if my budget allows (lol).
Thanks jdub, Iam holding off buying other cables. Iam nor looking for AC-10 for the amp and will move AC-5 to the preamp.
