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?.

As my Quintet is burning in and AC-12 is on the way, I tried the Hi-Fi Tuning fuse for my amp. I felt it adds a little of height and width to the imaging. Also there is a little bit of added realism, but at the expense of added brightness. I swapped back to the stock fuses. Do you have any experience with these fuses?

Not yet, I have been thinking about fuses though. I get to order my AC12 thursday. My Morrow Audio MA3 balanced should have about 360hrs on Saturday which should give me a good idea on the sound before adding the AC12.I'm using the stockcord on the amp at the moment. What IC's do you use? I have a mix of Morrow and AQ (Columbia and King Cobra). Speaker cables are Morrow's SP3 biwire.

I use Acoustic Zen Matrix Ref II from Pre to amp and Silver Ref II from CDP to pre. I cant use balanced ICs as my amp does not have balanced inputs. I think the HIFI fuses does bring in good improvement over the stock fuses. Parasound amp has 2 fuses for each channel. I only changed 1 fuse in each channel, which I think is not correct. I have to change both the fuses on each channel. BTW, I have not changed the mail AC fuse on the amp.

The fuse is driving me crazy!, Iam likely to return them and be content with the stock fuses as the Hi-Fi fuses is giving a negative impact on the system. I moved to Acoustic Zen ICs straight from Kimber PBJs. Happy with them.
