Garebear, keep them both if you can swing it. Because if you are like me and I suspect a lot of audiophiles switching things around on occasion is not only interesting but could possibly save you $$$ in the long run keeping audio nervosa in check. It also takes more than 10 days of audition to really to get to know how something really works in your own system, for me at least.
A hated question - Purist 20th Anniversay and the Cardas Clear Rev 1 interconnects
........I like them both in my set up ; Esoteric cd, amp and per-amp / Sonus Faber Olympica III's / Silver Circle 5.0 SE conditioner / Purist Audio 20th Anniversary cabling - interconnects and Limited Edition power cords / Cardas Clear Beyond Speaker cables. I added a Cardas Clear Rev 1 interconnect from the Esoteric K-03x to the pre-amp. I liked the way it sounds - clear ( ha ) focused and improved rhythm and pace.......added a nice warm sound. The Cardas was what $2,500 ...and the PAD 20th Anniversary retailed at $8,000. Okay why am I nuts here ...and any thoughts to those who have listened. I might ...might I say add another Cards between the amp and pre-amp. I borrowed one from the Cable Company and I am telling you the Cardas are very honest almost ruthless to the source. The last time I heard that was from Nordost - but the Cardas is just that , but adds a nice touch and I mean a touch of warmth.
