Suggestions for interconnects and speaker cables.

I need some recommendations for cabling in my system. Here's a list of what I'm using now:

Speakers: Wilson Audio Sophia's
Amp: Mark Levinson No. 383
CDP: Sony CDP-XA7ES

The current cables I am using are Acoustic Zen Holograms Mark 1. Interconnects are Luminous Audio Synchestra's. Power cord for the amp is Custom Power Cord Company Model 11. Stock power cord for the Sony unit. My room dimensions are approximately 13x15x8. I know its on the smallish side but things do sound pretty good :)

My music preferences include jazz, classical and acoustic rock. I do like a more "forward" sound also. The thing I've noticed so far is that there is a slight pronounced midbass hump that I would like to tame. I do enjoy what I have now but feel things could improve with "better" cables.

I know that cables are a personal preference and are definitely system and room dependent but any suggestions and comments would be greatly appreciated! Thanks!
