Really Long XLR

Once again, thanks to everyone for your comments and suggestions, One thing I do find surprising is the strong support for cables costing $1 - $2 per foot. Don’t get me wrong, I’m not looking for a reason to spend more than required, but for the main cable carrying the signal from preamp to power amp, I am truly surprised there is anyone suggesting this is the place where a $50 - $100 cable is the appropriate choice. This is going to be way more difficult that I thought. Luckily, I don’t need to make the decision for several months. I do like the specs and cost of Audio Envy O’nestian Matched pair.  OCC copper. They will build a 45 foot pair for $1200. For the DIY, so many to choose from.  And of course there is the Nordost Odin knock off from China.  🤣🤣🤣

Rather than a counterfeit from China, buy lamp cord from Home Depot. 

Even Home Depot has a much better sounding solution than lamp cord… not high end audio level, but much better. 
 

You buy their 12 gauge 3 conductor extension cord and cut off the ends. Obviously you don’t use the ground. This stuff is actually better than bottom tier / no  name… like Monster, Belkin, etc. Additionally it comes in that decor compatible orange / black stripes, so you don’t trip over it.

You do realize we are talking about signal wire?

Consider Blue Jeans Cable. They will run you about $250 for the pair.

I've used Blue Jeans interconnects, speaker cable and XLRs. The quality of construction is first rate. (Ultimately I replace the speaker cables with Kimber 12tc)

I run a BJC Belkin 15 foot XLR from pre to power and I am satisfied. Worth a try, I think.

Before you spend $$$$, anyway.
