Your Symphonic Line integrated is wired with Groneberg cable, why not call Odyssey Audio (no affiliation) and order a pair of their Quattro Reference cable? I bought a 20 foot pair for a grand about 3 years ago. I am using an Odyssey amp which is a clone of the Symphonic Line equipment and the results are amazing. It's like your amp extending all the way to your speakers.
Prior to that I had an expensive pair of Audioquest and a pair of MIT cables. The Gronebergs blow them all away. The music flows so easily with these cables.
