I purchased a set of the Aqueous 20th Anniv. Interconnects about a month ago. At first, I was concerned that I had made a mistake with this purchase. The interconnects (between my Audio Aero Capitole MkII CDP and my Audio Research VT100 MkII) at first sounded a bit strident. Not really harsh, just a bit tipped up for my taste. Being a HUGE believer in breakin, I reserved any final thoughts until I put the required 120 hours of breakin on the interconnects. My cables are 1.5mtr. so they probably needed a little more time, but, I can tell you, without any doubt, that after having them in my system for the required breakin, they are absolutely wonderful. I am, as they say, a happy camper, with no reservations about these interconnects (can you tell that I like them?).
What the Aqueous 20th Anniversary interconnects do for my system is all good. The tonality (to me, the most important aspect of a cables sound..or for that matter the most important aspect being able to enjoy an audio system) is neither bright, or dark, soft or edgy. The soundstage is as open as the recording allows it to be. They are extended on top without the edge (unless on the recording) and the bottom has nice weight (without being boomy) and definition. All of this, and they exhibit natural, rich sounding detail. They just sound, well, very, very good, and very, very right!
I now plan on upgrading my Musaeus speaker cables (talk about an over-achiever) to either the Aqueous or the Venustas. From what I read above, it'll probably be the Venustas. But, before I purchase anything, I plan on calling Purist to see what they recommend. Plus, I'll keep reading this thread for other peoples experiences with the new Aqueous.
Bottom line, for me, you can't go wrong with any of the Purist cables.
