Speakers I have Two in mine??

Hello FriendsYou a problem sick of my post's!!I have a pair of Zu Souls MK11, I like them, but wish, I have more bass slam, and a slight reduction in the treble, only just!! I live in a part of Aust, where there is no hi fi shopsFriends, I have been offered a pair of Gallo Reference 3.1's with a SA bass amp, at 2,000.00 Au, rare in AustI notice from my last post, that many people, had different views, thanksI own the Zu'sBut the Gallos, have come on the market, I'm very happy with all of my audio gear, except the speaker's, which will be powered by my Channel Islands mono blocks!!I wan't  your thoughts, should I stick with the ZU's, or should I go with the Gallo Reference 3.1's with SA Bass Amp??I just want options between the above, I have 48 hours, to make up my mind!!Many ThanksDavid
