I have my entire system wired with DH Labs BL-1 and D-75 interconnects and couldn't be happier.
The T-14 speaker cables are excellent also but there are more to choose from here too, namely Audioquest type 4 and Canare 4S11 starquad.
Don't buy into the hyper-priced cables... I won't say any more on that.
If you want to save even more money, buy it in bulk (Audio Concepts inc (ACI) and Blue Jeans Cables (BJC) have it), then get your favorite connector (I think the connector can have VERY significant influence). In fact I believe what many people "hear" is the quality of the connection as much as the cable so choose this carefully but, again, don't go crazy!!!
