Studios were around before Cube so if one is derivative.... Regardless, they won't sound the same as not even all the HiSounds sound the same. Studio V, A3, Rocoo-p and Rocoo-ba all have noticeable differences with the same SOC. They also measure flat so the differences aren't EQ. Doesn't mean the c30 may not be a great deal at it's price but it will be different. Using EQ would not be my way of equalizing the differences.
