Argento cables - any experience?

I have the Argento Serenity Reference interconnects and sp. wires. I find them very detailed and any high freq. harshness ime has been my room. One acoustical panel behind listening position tamed it right off. I personally really like these Argentos. Bettered Shunyata Python that I had on hand to compare. Wonder how much better the newer Flow is? Audioexotics rave about the Flow Master REf power cord....I'd love to try one.

I bought two of the latest Flow interconnects (the speaker cable will follow soon). and had the chance to compare it with the Serenity Master Reference. I can assure you that the previous flagship doesn't even come close to the performance of the Flow. The difference is dramatic. It is like you could hear the cables before and now you feel that there is no cable anymore. The Serenity Master Reference sounds compressed compared to the Flow. I cannot even imagine how the Flow Master Reference would perform...

Geopolitis, I see that Tidal is wiring at least the Contriva Discera SE with Argento Flow Power cable and that they are the importer for Scandinavia. I can only assume that the Contrivas I heard at CES were wired with Argento wire and they sounded great after the Ypsilons had some time on them. They other wires were the Stage Threes.

The system I am planning to build will combine the Tidal Piano Cera with the Argento Flow cables. I believe they are perfect partners and these are the combinations that both Tidal and Argento use for their own reference systems...

Geopolitis:
Just curious if you had a listen to the Piano Diacera as well? If so, what were the differences both in sound and price?
