Power cord choice?

Triode Wire Labs make great cables at reasonable prices. Maybe contact Pete and ask his opinion.
Pete uses very good connectors and his wiring is very good as well.

A CD player has a constant (low)current so you don't need a cable that can deal with high current transient spikes.

A Straight Wire Black Thunder II would also be a good choice and is around $500 I believe for a 1.5m length.

Power cords are really pretty simple.
They are filters.  If you can't hear any difference between power cords, you either are 1) blessed with pristine power, due principally to your location in the world, or 2) are cursed with some component(s) in your stereo that is such an underperformer that it masks the improvement the power cord brings.
I just switched from a $160 Pangea power cord on my Innuos Zen Mk III streamer to a $260 GR Research cord.  At first, I was shocked.  The soundstage collapsed from wider and deeper than my room to about 3' wide!  It sounded like the music was in a tunnel.  About 2 hours later (I'd left it playing), I was shocked again.  The soundstage was back to it's original size and I suddenly had the most dynamic and tightly controlled bass I'd ever heard.  It was not subtle.  Better than much more expensive systems I've heard elsewhere.  I couldn't stop listening for hours.

GR Researches power cords are returnable for a full refund for 30 days.

I haven't noticed any difference in my system. I did go with a power conditioner but the pcs did not appear to add or remove anything after that. I continued to replace the stock pcs with fancy ones but just to pimp the system a bit.

If you are curious about a new power conditioner, take a look at PI Audio's UberBuss. Very reasonably priced and as good or better as much more expensive PWC's.

Also, the power cable to the power conditioner is the most important PC in the chain.

If you are able to get a 20A or 30A dedicated line installed from your breaker box to your equipment receptacle, you will notice a big sonic improvement.

Being conditioned to first check Amazon for what they offer in terms of brands, I recently searched for power cables. I had just come from a showroom demo of McIntosh offerings, which included an unexpected, eye-opening demonstration of why they were using a $1,000 power cable. I had never heard or even seen a modern McIntosh component and was impressed by the beautiful power cable I assumed was native to McIntosh. I learned it was a special cable because it "sounded better". I was a bit put off that I was potentially not hearing the true sound of what I was there to purchase, the MA-9000. It still bothers me a bit that maybe it’s assumed at this level(?) that you either already have a "worthy" power cable will be leaving with the cabling heard in the sound room. Anyway, I asked that the stock cord be fetched so I could AB them. In the end I was shocked, awed, educated and disappointed. Yes, disappointed. I now had to have worthy cable. After all, we all want perfection, right? We all want to not be responsible for holding back our big investments, right? It’s how I’m built, so I was off to Amazon. The MA-9000 was home and needed to "properly" tap the wall. It took two days of endless research and I decided to roll the dice on the following:

I was sold on the image of how the cable is built / shielded, especially vs so many others. I have zero affiliation with Viborg or any other company in this industry. I’m simply a noob audiophile who recently dove into the hifi waters.

Realizing I’ve written a wall of text, I’ll cut to the chase. The difference at my home between the stock cord and this were exponentially more significant than the store demo. The difference was not eye-opening, it was jaw-dropping in terms of better dynamics, power, volume and detail. It’s something I now show friends and I love seeing their reaction! This is the best purchase I’ve made for so little money. I do not need to hear another cable because I’m happy.

The moral here is not to get a Viborg, but to test the waters before you spend big. There are diamonds in the rough. Best of luck.
