Original ProAc Response 2 vs. Gibbon Super 8

I have a pair of the original ProAc Response 2 with stands and am thinking of replacing them with the Super 8. Could anyone who has experienced both speakers tell me if this would be an upward move. The following components will be connected:

Quicksilver KT88 monos (60watts)
Reference Line Preeminence - Dual mono passive
CEC TL2 transport / DIY DAC
Merrill/Scillia MS2 TT
Michael Yee phono
