I've been experimenting with power cords and interconnect cables lately. Several manufacturers told me the most impact will "usually " be found by upgrading the power cords at the source and using the best interconnect at the source.

I have ref1000m amps. These draw a lot of current when powered up not so much after. I use basic cords on those. Higher grade shielded cords on source gear. The amps power supply seems designed well to have power in reserve when needed. So I have not felt a need for beefier power cords. The amps are very efficient sound great and never break a sweat. Beefier cords not needed as much in some cases compared to others. Devil is always in the details.
i have 3 ref 1000m amps across my front in a HT configuration. I have used Crystal Cable, Siltech and now Purist Audio Designs (Neptune). I can def attest to a change in the tonality as i moved across the power cords.
it may be that the power cords you have chosen actually sound similar and therefore you didnt hear much difference.
@thomaswv - Like you, I found good PC’s on my NAIM amp did not make an immediate noticeable difference - I had to find the right track that made the improvements more noticeable.
Those improvements are the micro details of the venue acoustics - now I know what improvement power cables make it is easy to hear and noticeable when you change back to a cable of a lessor ability.
I use the following DIY cables that I have compared to a few high priced products and found the others lacked the bass dynamics (slam) and very fine details of these
Check them out - despite their apparent complexity, they are pretty easy to build
