I don't have any experience with the Water interconnects but I do have the Earth interconnects in XLR. They are very good and I highly recommend them. Looking to get a pair in RCA as well. I wrote a review on them in this forum. Feel free to look it up for more details.
Audioquest Water
I heard through the grapevines that Audioquest discontinued the Columbia and replace it with a new interconnect named Water. Does any one know anything about this Water interconnect? I tried to Google it but could not get any info. Maybe Bo1972, our resident expert on Audioquest, can chyme in.
