Audioquest Robin Hood Zero

For sure the Robin Hood and William Tell outperform the former series. Though as Garth Powell enabled a major jump in performance withe the Storm series power cables, as big is this new generation of power cables. I truly understand that AudioQuest is very proud about it and it's amazing to see such a big difference between Castle Rock and Robin Hood for example. There is even another great improvement possible - if you go instead with the Robin Hood Zero with the Robin Hood Zero&Bass combo/bi-wiring version.

Stepped up to Robin Hoods from GO-4's last year - admittedly a wider jump than the OP is considering - but this was one of the most instantly, clearly audible upgrades I've ever made to my system. I was literally laughing at the difference.  Highly recommended.

I have audioquest Aspen. Tuesday my new Thunderbird zero cable comes in. Hoping to hear the same difference people have been saying. Both cables are the same gauge. Will be a good test. 

Apologies for bringing back an old thread.  However, I just made the jump To Robin Hood Zero/Bass cables this week and the difference between them and my outgoing Rocket 44 cables was astounding!  Stronger punch down low and the detail throughout is incredible.  Nearly purchased the William Tell cables but for flexibility sake, I am glad that I went with the Robin Hood.   

@rjtrout,
Glad they worked out for you. And Welcome to Audiogon.
