I own a Luxman 590 AXII however I have only used RCA interconnects. With that said (due to my experimentation with my Plinius SA reference amp and Audio Research REF 5SE) I did not find a difference using RCA vs XLR interconnects using 1/M and/or 1.5/M interconnects of the exact same type. The confusing glitch when listening between RCA and XLR is the XLR will sound approximately 3db louder with the volume knob set at the same level. It's my opinion that a regular length interconnect does not need to be balanced unless you are running long distances. Regardless which way you decide to go, depending on the dollar amount you want to spend, I recommend the Zivfino Fusion Interconnect, I'm currently using the Grand Lavricable 5/N silver interconnect, and/or the Infigo Sparkle or Signature interconnect, which I've read very good comments about and should receive a demo Signature interconnect today.
High Quality Interconnects for Luxman L-590AXII
I would like to seek experiences from current owners of the Luxman L-590AXII (or other Luxman models). Have you tried different interconnects particularly the balanced XLR versions and heard a profound difference with the cables? I only compared a $1,500 balanced XLR to a $500 single-ended RCA and so far the balanced XLR sounded superior. I believe the balanced connection of the Luxman is capable of producing better results when compared to single-ended.
Has anyone compared different balanced interconnects on the Luxman and noticed a difference in sound quality between the cables?
