In a world of thousands of cable choices who can say? My own experience (40+ years) has been that single ended cables sound better in my reference system.
Should I upgrade to XLR interconnects?
I recently purchased a Marantz SA-11S3 SACD player to pair with my Marantz PM-11S3 integrated amp. The SA-11S3 has balanced outs and the PM-11S3 has balanced ins. Currently I am using RCA interconnects. Is there any benefit to upgrading to balanced for these particular units? I do not want to drop big bucks on new cables if the benefits are minimal.
