From what I have read, the Vox AC30CC2 is better than the AC30C2. Conversely the Vox AC15C1, is generally viewed as an improvement over the AC15CC1.
I had a Vox AC30CC1, nice amp, after some tweaks.
If I bought another Vox it would be from the HW series, like the AC4HW1, Ac15HW1, or AC30HW1. I currently have a '66 Vox AC50.
