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.

 Will try Blue Jeans Cable but wondering if there are other companies that can do that length. I suppose I can also try DIY.

I have purchased all of my Canare L-4E6S RCA interconnects from Redco.  Just order what you want on their online order system and wait a few weeks for the build.  Very reasonably priced and high-quality workmanship (I know, it's just an interconnect).

 

 

 

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.

@dougthebiker for the win on solving the hum.  Thanks!  One of my amps - Schiit Vidar - was in the system after swapping out the monoblocks. When I disconnected everything from the amp except speakers and power, there was still that hum.  Couldn’t find my cheater plug to float the ground so switched back to the Belles Aria Monoblocks, which I just bought.   No hum at all. Dead quiet. Plugged in the 15’ interconnects from Schiit Freya + and still silent. Music sounds great!  Success!  
Thanks, all, for the recommendations on interconnects. Moving up to 25’ and just have to pick the right one for budget and SQ. 

… so switched back to the Belles Aria Monoblocks, which I just bought.

The gear shaming is getting a bit difficult.
