I have them, but can’t compare them to Rocket.
I was running very short Cardas Golden Reference from Bel Canto monoblocks to Audiophysics Tempo 6. I needed to move the monoblocks further away, but couldn’t stomach the $$ for longer runs of the Cardas. I sprung for the Audio Envy, and was pleasantly surprised. They appear to be very neutral. I honestly don’t hear a lot of difference between the AE and the Cardas. Cardas may be a tad warmer. Now I added the AE balanced interconnects, too.
Things sound “right”, so I’m not currently tempted to futz with it.
