I'm with gamerwolff, Thread Heaven is a must-have, especially if you use metallic threads regularly.

Yes, go slowly and carefully. Use one strand of thread - sometimes I do use two but usually one is enough. And finally, keep the lengths of thread shorter than you would use for normal cotton thread.
And don't worry about the sound, although I would say that if you are hearing a sound you might have more than one strand of thread on your needle?
If you still can't manage with the DMC after all our tips, I've heard that Madeira metallics are very nice as well!
Hope we've been able to help you!
