Using a bryston 4b 4b stereo amp with an intg. amp

I have a bryston 4b 4b and would like to use it for additional power with a musical fidelity elektra E100. How would I connect the two - I think the bryston has XLR outputs - not RCA, if I'm right - where do I find an adaptor?

I had a similiar setup - you can get leads with balanced connections at one end 1/4 phone-jacks or XLR feeding into phono leads ends on the pre-amp.
