Proceed AMP2 vs Acurus A250 change cables?


I rec4ently purchased a Proceed Amp 2 and ran it with my Classe CP-35 preamp. Previously I had been running the Classe with the Acurus A250 amp. I have Snell D series speakers. The Proceed seems to be more musical and open but lacking some in bass. Would a change to balanced interconnects improver the lower end?
