Need 25 foot interconnects

I just moved around my equipment so that the rack with the preamp and digital sources is on the left side of the room and the monoblock amps are just behind the left speaker on a short platform on the floor.  I’m using a 15’ RCA interconnect right now, but want to move each monoblock to just behind each speaker — which means I need a longer cable.  The monoblocks are unbalanced RCA input only but my preamp can do balanced XLR or unbalanced RCA out.  Would a balanced XLR cable plus an XLR to RCA adapter work for this setup and be my best option?  Or should I just get a Belden (or similar) 25’ unbalanced RCA interconnect?  Or is there a better option?

Hum is more frequently a grounding issue than noise picked up by shielded interconnects in my experience.

A quick test is to float the ground on your components, particularly the amps, and see if it goes away.  If it does, it’s not your interconnects.

Just use ungrounded adapter plugs or pull the ground pins temporarily.

You’re getting some bad advice here.  As one respondent correctly said, unless the amp and preamp are both fully balanced, XLR’s do you no good.

 

For DIY, I recommend NeoTech NEMOI 3220.  Single crystal. OFC.  Can’t be beat at the price.  Not cheap but cheaper than finished cables of that quality.
 

Cables are VERY important if you’ve got anything better than entry level equipment.  Put some quality RCA’s on them and you’ll thank yourself later.

The NeoTech I referenced above is Ohno Continuous Cast, single crystal copper.  Far superior to Mogami and Canare - I’ve tried both - and MUCH better SQ than Blue Jeans.
