Simply one pair of interconnects from Silnote. But that will complete all ICs being switched over to Silnotes. I am always on an extremely strict budget and as I swapped in each Silnote IC over time the sound became more and more organic, to my liking. Hoping this will continue that improvement. If I had the scratch I'd love to compare my current speaker cables, Harmonic Tech Pro-9 Plus, to new Silnotes, but unfortunately I don't see that kind of dough in my near future. Maybe next Christmas?
