Audio compatability and testing

I was combining a Musical fidelity electra 100 integrated, carve pre amp and proac tablette speakers for a small bedroom system.   i heard what i can describe as short sqacky sound.   now no out put.   First Is the MF 100 an amp the can function without a pre amp,  if not how can i test both pieces to see which one has the output problem.  Thanks
I don't see that you need to test both pieces, the MF is an integrated amp, if it has no output its the problem, if the output is fine, it's the preamp. Seems pretty simple and straightforward.
Don't use 2 preamps. Just use the MF 100 and it should sound fine.
short sqacky sound
?? Just off the top of my head, the sounds like the speakers might have been toasted.
