I cannot remember how many times I have said you don't necessarily buy speakers to match an amp, unless you have some very low output valve device, you get speakers that work with you room.
The Cambridge has enough power to drive most....
You don't mention your room size so cannot help here. Go out and audition would be my advice. If you are spending this sort of money you have to. Buy local, by that I mean don't pay over inflated import duties on foreign speakers and the like, a nd certainly not those you cannot return to a local dealer should the y go wrong......
Can you audition any where you live?
Speakers, room, and your hearing are so individual that you have to audition yourself. Sure I could recommend my usual go-to speakers in this price bracket but there is never any guarantee they are going to work for you, unfortunately it's not that easy.
