recommends for interconnects?

The new Wireworld 10. Eclipse, 

Is it possible? Only you can determine whether a cable swap will change (good or bad) the sound of your system regardless of product accolades and claims.

If I wanted my system to sound better, I would by a better speakers, DAC, amp, or preamp and use my same cables, but that is just me.

But this hypothesis can be easily tested with a cheap pair of Mogami 2549 or Belden 1800F cables before investing in a more expensive set.

If your system is fully balanced source to output, I would say no, not much possibility but further investigation is required. Have fun :)

@derbim on a used market for under $2k you can try Nordost Tyr 2 XLRs. Excellent cables. Kimber KS series is very nice. If you’re looking for a more detailed sound try Kimber KS1126. 
But…you will disrupt the synergy between interconnects and speaker cables. With McIntosh you may be ok as it tends to homogenize things to a certain degree but you never know until you tried.

Again, if it ain’t broke, don’t fix it. 

Mogami Platinum XLR. 

Not as exciting a purchase as the boutique or underground cable makers but a fantastic balanced cable nonetheless. $2-$300 for a single pair.
