What was the first power cable that you noticed a difference in the sound?

For me it was Shunyata power cords.  75% of both my systems are wired with Shunyata interconnects.

I can’t find the A/C Master Coupler on SR’s website.  When did it come out and what was the price then?

Thanks!

Could you hear differences immediately when you plugged them in?  What are you using now?

Are you talking about the Audience F3’s?  I bought one for $300 when they first came out and ended up buying two more for $300 total about a year later.

I'll have to go with Lessloss. Made be a believer.

Going from supplied cables to a BLE Design (on Ebay from Florida) 10 gauge OFC with rhodium plated contacts yielded darker background and a slightly more neutral color. $35. Using them on phono, pre, and subs. I’m good.
