PAD Aqueous 20th Anniv. vs Cardas Golden Ref. IC's

Would you consider an upgrade moving from Cardas G.Ref. to Purist Aqueous 20th Anniversary XLR interconnects?

I had all Cardas Golden Reference cables in my system before, then I upgraded power cords purchasing Kubala Sosna Emotion for the Accuphase DP700 and Purist Aqueous 20th Anniversary for the Luxman 509u.
Speaker cabkes (double pair-biwiring), balanced interconnects and 20A power cord for Purepower 3000 AC regenerator are still Cardas Golden Reference (I am planning to te-terminate the 20A p.c. with Oyaide P079-C279 gold plated plugs like those on the Purist power cords).

My system is solid state with (wonderful but still) digital source and B&W 803D speakers, so IMHO cables should stay on the warm side to avoid any coldness/hardness/edginess/forwardness/listening fatigue.

My aim is a full bodied sound with rich, natural tone and sweet but still extended, not veiled highs, I think I am very near to my "perfect sound".

I tried K/S Emotion XLR IC's but compared to my Cardas G.Ref. they sounded too much "neutral" to my ears; now I can purchase a pair of used Purist Aqueous 20th Anniversary XLR interconnects without auditioning them in my system.

I guess the Aqueous IC's sound like the power cord I use on my integated amp, but it would be better if I had some opinions of people who compared them with my Cardas Golden Reference.

If it can be considered a side-grade (expecially if I'd lose bass weight) I would save my money and keep my Cardas.

Many thanks
