@toolbox149 : I posted something on this back on my 11/5/2021 post. Copy / paste a portion of it:
I touched upon this briefly on my previous (long-ish) post above, but a to expand a bit further:
The only cables I was able to compare (and own) direct between Prima MKII and Silver Darts are power cords and speaker cables. Interconnects --- I only own the Silver Darts which I bought from the start.
Silver Darts are NOT a huge improvement over Prima MKII, and Prima is definitely better value for the money. Of course, this is only valid for me, my equipment, my ears, my room. Other people with more elaborate systems and better trained ears may think otherwise.
If someone forces me to "quantify", Silver Darts are perhaps 5-10% better than Prima MKII. Same overall tonality and timbre, but maybe a bit more coherent / focused, and a bit more "airy".
My advise, if someone is looking at Zavfino: if in budget - you are better off doing a full loom of "lesser" tiers (i.e. Prima, majestic, Fusion, etc.), than buying one or two silver darts.
