Benfits of upgraded connectors


I've been looking into upgrading/changing my ic's and of course have noticed that many mfg's offer and charge for "premium" connectors.
Is there a sonic benefit with these connectors? For example, will an upgraded Cardas connector sound better than a standard RCA connector on the same cable?

I removed the connectors from my speaker cables and can tell you I was extremely dissapointed with the change in performance. Even my 10 year old daughter could her the difference. She immediately commented - Dad, where did the music go?

I put the connectors back on the cable and connected them again to my speakers - low and behold - music started playing again.
Well... I took the plunge and replaced the terminations on the Kubala-Sosna Expression power cord that runs to my amp. I replaced them with Oyaide M1 / F1 terminations. The difference is impressive.

One of my reference CD’s is the first cut on the Chris Rice album “What A Heart Is Beating For” (So Much For My Sad Song). On that song there’s a rhythm guitar that comes in on the right channel that either gets more or less pronounced as I make changes to my system. With the Oyaide M1 / F1 terminations, the rhythm guitar is much more pronounced.
