IC to mate with oppo 105: mostly 2 channel

recently bought an oppo 105 and one thing I notice for certain is the depth of the soundstage. I am looking for an excellent interconnect to match it. very open to some suggestions. I know that I should have a price range but I am taking a backward approach hoping i can read some reviews and pick one that I can afford. I may splurge and spend more than i can afford if I am somewhat convince. I do have an older SR kaleidoscope and i am considering another SR or cardas....Thanks
