Good speakers to match with Spectral DMA-50


Almost have everything but the speakers - DMC-10 pre is in the works and the speakers are the last thing I'm getting. I've had a few suggestions. As this will be my first proper "audiophile" setup was hoping to get some more input. I have a pair of StraightWire Wave Guide 4's and have been offered a pair of Magnan signature speaker cables as well. Any reasons I should consider something different?

I appreciate the input and suggestions very much. As for the cables - any suggestions on which may be better? The Straightwire "Waveguide" 4's (which I can't find much info on) or the Magnan signature's? Only drawback with the Straightwire's is they are much longer then I will need.
