Your jaw dropping cables

So far, in my system the most dramatically positive cord changes I have made were the Elrod EPS 3 Signature AC cord on my Ayon Amp, and on the other end of the price scale it was the J W Audio speaker cables, which replaced many sets I have tried at 15 times their price. Both cables gave me a lot more dynamic energy, clarity and detail with no negative colorations. Both were very welcome changes for the better, one at a big price, and the other got me enough money back after selling my previous speaker cables to by the Elrod!

I guess jaw dropping could be good or bad. Went from Purist Audio Aqueous to Audience Au24e (speaker and interconnect) - WOW talk about extremes.

Ended up selling both and going to Kubala Sosna Fascination - the prefect balance in my system.

Morrow MA-3's!
Have had a number of various cables in my systems including Cardas, A'quest, Tara, Tributaries, Goertz, AudioStream, et al.
Read good things about Morrow here on A'gon. Bought my first pair 6 mos ago.
I have since replaced every interconnect in my systems to Morrow.

Van den hull works with any system, neither adds anything nor substracts anything, the way it should be. Currently using Integration Hybrid.

Probably the most jaw dropping expeience I've ever had with cables were the Nordost Valhalla. Stunning cables, though after time I found them too difficult to live with long term. They were so revealing that I found my listening sessions growing shorter due to listening fatigue. I still say they are the best demo cables in the world, but I wanted cables that I could listen to for hours everyday.

I found two other cables that I would say tie for the best for long term listening, IMHO. The Jade Audio Hybrid Gold and Stealth Indra, They are very different, the Stealth being almost as transparent as the Valhalla, but a bit more musical. The Jade being probably the most musical cable I've ever heard with incredible dimensionality.

Competitors? Far too many to even think about listing, sorry.
