Can Quads be directly hooked up to an amp?

I have a pair of Quad esl 57's. My source is a Shanling t200a sacd player. I am going to purchase an amplifier. I have been told I can hook the Shanling with its own power source and remote directly to an amp and the speakers directly to the amp without a need for a preamp. Having never done this before I am leary of causing damage to the quads. Can this be done? What should I be cautious about? Thank You
