Suitable amplifier for ifi components

[StefanoFereri]

Hi,

I'm looking for a solution to stream music via wifi to some passive speakers in our office (Bose Acoustimass 5 Series III). ifi Zen stream and and ifi Zen DAC seems to be an excellent value for the money. But as far as I understand I need an additional component, an amplifier. I researched the ifi web site but to be honest I am not sure whether they offer an amplifier for connecting passive speakers. Can anyone help please (or recommend a mini-amplifier that is roughly in the same price and quality range)?

Thanks and regards
Stefano
