Audioquest thunder vs tornado HC powercords

@milpai yes 100% system dependent. Yes give AQ a shot. I would bypass Thunder and start with Tornado or Hurricane. Be careful buying AQ on a used market. Too many fakes. I highly recommend TMR as they will have not only a genuine product but also a return policy. They have a good amount of used AQ power cords.

Although AQ Thunder, Tornado and Hurricane are made in China, they’re pretty high quality. 
 

Here’s a 1m used Frey 2 from TMR

My guess is that cables are system dependent. 

I've been saying no audio and cable company knows how to make the power cable properly, except me.

The synergy (system dependent) between cables and components is because the cable or component is not perfect. If a cable is complete, that cable sounds always similar and great with any component. Alex/Wavetouch audio

I am finding good success with Snake River Audio Signature Series, I have two and another one on the way. (Streamer, DAC and AMP)

Iam using tornado on my Marantz Ruby sacd player, its a well balanced sound on my system, iam using tube amp and tube preamp.

Milpai if you audition tornado let it settle for 50 hrs if used if new maybe more, I feel you will like it, Music direct has like summer sale pre pandemic, I grab 1 hurricane, 1 tornado, thunder as well without return policy. Knowing Audioquest pc storm series are good. For the price I took the risk. I was happy to let you know , my plinius sa 100 is happy with the HC hurricanes. My thunder is used on my conditioner. All work good.
