PC suggestions for a Gryphon Diablo 300

Thanks for all of the advice williewonka!   Especially, the speaker cable comments.  I had no idea on that. 

Interesting comments on powercords having less of an impact on amplifiers versus other system components.     
I currently have an Ayre KX-5 Twenty preamp and VX-5 Twenty amp.   I've noticed that while the KX-5 is definitely affected by powercord changes(the Cerious GE sounded the best), with the VX-5 I noticed little if any change at all between powercords.  (My Gryphon is due to arrive in a couple of weeks.)

With that said it may make more sense for me to save my money on the powercord and use it toward Speaker and IC cables.   This may have more of an impact.   Currently I have Wireworld Eclipse 7 throughout my system.

Appreciate the comments!

Thanks lak.   Robert at Cerious Technologies has always treated me really well.   I may give his SC and XLRs a try.  I've been impressed with his GE Powercords.    
I've also always wanted to try Nordost as well....Pretty pricey though.
