Hi: Cables are a tough one! Everyone seems to have a favorite? Mine are mostly Purist Audio Design. I lucked into a "stash of them" at almost yard sale prices! I plugged in a pair of Proteus between my Old Audio Research SP5 and D100A...and they came ALIVE!!! The Proteus was missing a tooth, so I got them free. The Retail was $2495.00.SCORE! I had Kimber PBJ in there before( Still a very good cable). I am always on the hunt for cable? You never know what someone else has given up on? Great and very expensive cable can sometimes push your system towards Brightness or Analytical sound. Cable seems to be a QUEST for what sounds good to you, what you can find and afford now and the future; plus what matches with your equipment in your acoustic environment. Experimentation I believe is key. If you have a "static" situation, replace one set of cables to see how it affects (YOUR) sound. There is so much information on forums that can help. Proteus is a keeper! Go to the next need and build brick by brick; keeping a solid foundation, so you always know where you are at in your system process. Who thinks they will get a $2495.00 RCA cable for free. It turned out to be the foundation of my whole system. I bought Purist IEC's, XLRs more Proteus RCAs and several speaker cables( Venustas) and all at Best Buy cable prices; from that same source. I got more equipment to utilize the cable! Backwards compatible way of building a system? The cable was older, so there were reviews and information to avoid common pitfalls of mismatched equipment. Stranger than fiction? I bought an Audio Research PH3 just to utilize the two pair of longer Proteus and they retailed at +$5,000.00 each. My Phono section retails in at $12,000.00 list? My cost around $1,000.00! That is how I ended up improving and upgrading my system. I like the sound, I am very happy. I dreamed big but was still budget minded. Just something to think about on your (Neverending?) Quest for cable. Your whole Life is in front of you! Enjoy the Quest.
