??? Which XLR Interconnect ???

For $349 you could do far worse than these Acoustic Zen Silver Refs, and seller offers a 30-day return period.  They’re very neutral/transparent but still offer very good tonality and excellent and expansive 3D soundstage.  Best of luck.

Thanks @soix ,I suppose I should have mentioned one of the reasons I chose the 3 I did(besides build quality,materials & cost)was because I need 3 meter cables & these are all available in that length...

I use DHLabs until my system if fully broken in and I completely understand what it sounds like. These are my goto budget wires. They are great for the money and very neutral. Only then do I try and choose cables and interconnects. The exact sonic characteristics / desired sonic character is dependent on the system / user. So, you need to completely understand how your system sounds before choosing the most complimentary wires. 

@freediver what are you using now?

If you really must use long interconnects I would say try Bluejeans XLRs. In my opinion cheap cables built by some of these manufacturers you listed want to  pretend to be what they’re not. This results in some sort of unwelcome coloration of sound almost always. Bluejeans don’t pretend to be anything special. They will give you honest view into what your components are doing without dirtying up the presentation with some emphasis in one region or another. 
No they’re not the best cables out there. But they’re not going to mess anything up for you. If anything use them to get a baseline. Long interconnects is not the best idea though. Hope there’s a good reason for this. 

I concur with others, start out low cost until you have a feel for your new system, then spend some cash to get the ones that complement it best. It is a pretty critical piece of the system.
