Really Long XLR

Moving your equipment can from between your speakers can have a very positive effect. I think mine are 25 feet or so. Depending on your system the quality of the interconnects are important. Fortunately this time I was able to buy the same quality level that the rest of my system has.

I would recommend looking for a used set on used cables and Audiogon. Granted the probability is not that high… but something of that length is going to stay on the market for a long time. I think I have seen some in the past.

OP,

You have a very nice system. I don’t recommend going bottom tier stuff like Blue Jeans, Belkin,, etc or lower tier like Mogami. My experience with these have been they are no better than what you get free. Maybe do it yourself… but consider saving up. You are talking about a critical run, with very sensitive speakers. 
 

Consider the tonal balance and detail of your system. Research and maybe save a liitle. 

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.
