One thing I would note about Zavfino is they sell direct at low margins, so without the massive distributor/dealer mark-ups they do represent very good value for the money.
Like any brand they get better as you move up the line.
Their Fusion interconnects are much better than Arcadia (I use both but the Arcadia is in a CD player I rarely use)
The Nova speaker cables are very good for the money but I recently replaced them with Acoustic Zen Hologram II’s which I’m much happier with.
I ordered the AZ’s with spades (first time using spades) and connecting them was a bit of a challenge because these cables are really stiff, but I made it work, so all good but just be aware of that.
I’m also a fan of DH Labs, I have their ethernet cable and just ordered a USB cable to replace the Zavfino USB.
