Tim,
I have no experience with any of the Rocket series cables. So I just don’t know. The Earth series cables i had been using (Volcano for Mid/Treble and Caldera for Bass) served me well for a long time. The mid bass once I got the Treo CTs was too thick and heavy thus obscuring details in the mid/treble that I wanted to hear. The Clear Days solved that problem for me.
