No one talks about Purist Audio Design cables.

I had Purist Colosus .....it sounded too much like tubes.....too colored, but in the right system a great cable

At the time I ran PAD cables was running push pull EL34 and 845SET amps with modified Merlin VSM and various Alon open baffle speakers, also loved Kimber Tri Focal XL with the Alons. Then I got the Klipschorns, more sympathetic with Cardas Golden Refernce which I've always maintained in my speaker and IC collection. Cardas  GR has always been my workhorse IC cable, tried many others, just a damn nice cable. Issue with Dominus was overly resonant bass wiith Khorns, especially the liquid, Ferox better but then lost some of the lushness in mids. Kimber was a tri wired cable, only need single wire with Khorns. Generally, I like to stick with a single type cable in all uses, voice with things other than cables, exception is power cords.

Have had Elementa and Aqueous speaker cables for decades; Aqueous still in use in my living room system; Elementa in storage (replaced by much more flexible Morrow SP-4 cables).

FWIW, which may be very little, I had a negative reaction to a pair of Purist Audio Design Aqueous 20th Anniversary speaker cables that I purchased (and quickly re-sold) on the used market. It may have had something to do with system, but I went back to Audience cables, which had been my choice for years.

I was using a (high-quality) GATO integrated amp, and Harbeth 30.1 speakers.

I frankly can't recall the details, but I know that I much preferred the Audience AU24e that I had used previously.

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 ?
