+1 for DH Labs cables on a budget for sure.
Used them myself before upgrading.
One way to get a lot more cable for your money though is once you have semi decided what you might like to buy, go look for them used here or on eBay.
That way you get a lot more bang for your buck.
For example if you had a budget of 125 for a pair of interconnects you most likely will get a used pair that originaly cost at least 250 for your 125.
And they should be nicely broken in to boot!
I have only ever bought one new pair of speaker cables in my life, and they ended up being returned...lol.
All my cables and subsequent upgrades have all been purchased used but not abused!
Good luck and welcome to the ever maddening group of "cableguys"
