Rilou, I am unaware of the total cost of both alternatives. For the sake of argument, let's suppose they are equivalent.
If you are planning to go for a matching new set of IC and SC, then, my preference would go to Argento Flow. I repeat my previous statement: it is a combination "made in heaven"
To be sure, that is not a judgement on the intrinsic value of other products, but Tidal and Argento are completely symbiotic and therefore "a sure bet" that will probably not be topped.
