I'm considering replacing the power cords with something better on my pt1 and a2 combo. Has anybody had any luck with better sound quality doing this?

Might I suggest an inexpensive and intuitively "non-audiophile" option?
Try using no-name 18AWG computer wires.
If you want to know what I think of them (and why), you'll have to try them yourself and share what you think of them here.

Take your power cord(any power cord) to your local electrical supply house where licensed electricians are in and out of there every single day…… Put the wire on the counter and tell them what you’ve got in mind and see what they say… more importantly, see if they’ll look you right in the eye, without cracking a smile

“Licensed electricians” have NO training on how ANY wire might sound in audio use, and are therefore TOTALLY incompetent to tell you ANYTHING about wires except for:
1. What is the maximum current this wire will carry without overheating?
2. What is the resistance of this wire (for a known length & AWG?
3. What will the project cost of wire be for my intended job?
Beyond this, you might as well ask your mailman what SHE/HE thinks of the wire. Don’t ask a chef about particle physics; don’t ask a licensed electrician about audio wire.

Part of the reason I'm asking is because I feel I might want a shielded cable between my power conditioner and components? Any serious thoughts on this? I could do without the smartass comments from keyboard warriors with no personal lives.
I replaced a power cord on my main system with emotiva's 3 prong power cable, which was an improvement.
I have minimal experience with c7 cables

The only advantage of replacing the power cords is to prevent EMF from entering the cable so less noise. You just need to be sure that the cable is shielded to drain off any EMF that might try to get in. Here are some really good cables - gr-research.com/product/b16-power-cable/ |

What a prospect indeed to have to invest another $400?!?!?! in the plug after the fact I’m sorry I just don’t think so. |

You couldn’t be more wrong about that and clearly you haven’t spent much time around electricians….some that I know have some pretty serious audio gear The fact that you know some electricians who also like audio does not matter. Show me any ABET-accredited electrical engineering program in the country that has any mandatory course about audio wiring. Anyone? Anyone? That said, 405x5 is absolutely correct about audio equipment having EMF rejection built in. The ONLY place where shielded AC cords would be needed would be in stage, church, and/or auditorium wiring where there is a LOT of EMF from unshielded lighting equipment. |

It’s OK, boom but you’re cherry picking! Electricians worth their salt know exactly what’s going on and if a problem comes up after the fact that’s generating noise they know how to deal with it. it’s all just part of the job, although in commercial electrical, which is what I was involved in, stuff like this rarely ever came up. |

I have minimal experience with c7 cables If you replaced a power cord with an Emo cord and heard an improvement, then the original cord must have been defective. If you're using Emo gear (the PT1 you mentioned), then they supply a cord that is sufficient for the electronics they're selling and replacing it won't make any audible difference. That said, here's something that should inspire confidence if you don't mind paying more than 2x the cost of the amp itself: www.amazon.com/AudioQuest-NRG-Thunder-15A-1-0m/dp/B077J98CJ4/ |

Wow, I found shielded cables from $30 to $50. No wonder some of you get so butt-hurt over the topic. I would never consider such ridiculous cables.
