86-87 dB sensitivity speakers

[HC515]

Will a 35W amp be enough to play these? I bought a Cambridge AXA35 thinking I was going buy high sensitivity speakers but now I'm leaning towards speakers in 86-87 range. Wonders if the Cambridge is going to struggle with those speakers. The speakers I want are the Elac Debut Reference which will probably be 6 ohms.

I asked Elac and speaker specs have not been released yet. Speaker is due for release in November but I'm guessing specs will be similar to previous models in the Debut bookshelf line which had sensitivity ratings around 86-87.
