I have a McIntosh C220 preamp/MC402 power amp driving Magnepan MG1.6 speakers, with a Bluenote Stibbert CD player. Tried various combinations of cables and interconnects over a year, and then, I used MIT CVT Terminator 2 right through (source-pre, balanced; pre-to-power, balanced; single wire to the speakers). That settled it for me once and for all! To think I never used to like MIT cables in the past ... I used Furutech power cords on the pre and power.
Another good single-brand system would be the Excalibur II from Audio Magic.
