Lessloss DFPC Signature VS Sablon Gran Carona

I use the Lessloss origonals and Sablon Robusto as my main power cords. They are more different than one better than the other. The Robusto's are on the rich side of neutral, I believe Mark partly produced the Grand Corona, to get nearer neutrality. Both are truly excellent and great value. I have'nt heard the signatures

Rgwrjs If you have heard the Robusto's, did you hear a lot of difference between them and the Gran Corona. Mark lent me a Uber Robusto, the prototype of the Gran Corona and I have to say I did'nt hear an enormous difference. I am interested in other peoples views on this.
