No one talks about Purist Audio Design cables.

I have Neptune Luminist Revision RCA interconnects and like them a lot. But it is not exactly neutral cable. Wywires Diamond is overall  better but Neptune has its charm. Huge soundstage and tube like qualities.

If I remember right, Aqueous uses Contego which is sort of a mixture of fluid and Ferox. Never tried them, though.

I use old Dominus Ferox power cord with the VAC Avatar SE tube integrated amp with great results.

And believe it or not, I still use the original Purist Colossus fluid speaker cables. They are probably over 30 years old, I had them refilled with the fluid twice by Purist, more than 10 years ago the last time, I think, and they are an excellent match for my warm sounding speakers. Colossus used to be Purist's best value cable, no wonder you can't find it. I mean with fluid, at some point Purist stopped refilling old cables with fluid and offered to fill them with Ferox. I tried it with RCA interconnects and Ferox completely screwed up this cable.

sns, what do you use now ?

Never tried Audience cables but heard many good things about them.

Currently I see no reason to upgrade any cable or power cord that I have.

Anyone familiar with Echole cables ?

ohlala,

Did you compare old Dominus with newer Neptune ? Is your Dominus filled with fluid or Ferox ?

Old Dominus is almost impossible to find, either interconnects or speaker cables.

Dominus fluid cable will remain a classic, and Colossus fluid was their best value cable.
