I need advice on Dissimilar runs using XLR

The rule is always the same length. I have never broken it.

Cables can be looked at as having hundreds of small capacitors per inch where different electrons are detained by very slightly different amounts. Often why single crystal, or fancy metallurgies are employed in high quality cables. So by shortening a cable you are really compounding differences in arrival times.

Will you hear it? Hard to say.

Whether to do it or not depends on your goals. If it is to have a good sounding system, it may not matter. If you are going for the best possible you can achieve, then no. Really tiny things add up… always degrading the sound. Truly great sounding systems have no compromises on the little stuff as well as the big stuff.

Could you please relate your experiences that support your supposition. What brands, differential lengths, and components were involved in your testing?
 

I have always desired to take some shortcuts. Wasting money has never been something I like to do. 

Google is your friend. @ghdprentice 

So, you really have no experience. You are just parroting something you read online.

I have googled why smoking is good for you and discovered that doctors and religious people confirm smoking is good for your health. Also, that climate change is not real, despite the conclusion of dozens of peer reviewed scientific papers, dozens of statements issued by scores of scientific communities, as well as overwhelming heat waves and storms well far outside three standard deviations of normal. 
 

Maybe google is not always the right source for info, especially when you can research it yourself.
