guarneri memento vs olymica 3

Hello all members !
I consider buying a pair of sonus faber speakers.
Narrowed my search down to guarneri memento and olymica 3.

Olympica’s i can get almost new but guarneri’s are few years old.( almost same price )
I understand they’re different kind of speakers but i could always use a sub with mementos.

Still dont’ know witch amp i would use. For now i only have ps audio DirectStream DAC.

Whats your opinion? Full range or monitors with sub ?
Witch of them get better soundstage and will sound more natural?
Any amp recommendations ?

Thanks in advance !!!
