@audphile1 I think you’ll find that Zavfino cables have an exceptionally linear frequency response, particularly compared to pretty much any cable near their price, once they are fully broken in, perhaps closer to 300 hours than 200. When mine were new, they were more forward sounding, slightly less transparent, and highs were not as extended. Give them time.
My experience is very similar to how Juan Manuel described them. I really wouldn’t change much of anything he described.
The only thing I would add is that even though they are quite open and extended on the top end, I hear the lowest sub-bass region is being very slightly rolled off, including the all copper cables. This may just be my preference speaking, as I like to have a sound signature which has above average sub-bass energy. I’m using a non-Zavfino power cable on my DAC to achieve the sub-bass energy level I want, along with a couple other sonic qualities. However, I’m very picky about bass presentation, and the Zavfino cables are super transparent and fast throughout the entire bass region.
I found that for my subwoofer, this desirable quality of bass response can be brought forth even more by using multiple Zavfino all-copper cables in the signal path closest to my subwoofer. Specifically, a power cable on my preamp, an interconnect from there to my sub (an Arcadia), and a power cable on my sub.
Overall, I’m very happy with them now that they are well broken-in. Five of my eight power cables are Zavfino, and two of the five interconnects that I currently use are Zavfino.
