Low Volume Listening - XLR Cables ??

My Wywires and Clear Day balances cables do very well at lower volume levels. I’d say stay away from warmer sounding cables that aren’t revealing. I’ve found over the years as my components and cables have improved and my system has become more revealing I listen at much lower levels.

The concept that a cable has an optimized volume level is somewhat strange to me.  Are you suggesting that a cable can mimic the Fletcher-Munson curves?

If the Bel Canto utilize a true Balanced protocol, then distance should have no effect on sound reproduction. That's why they are used in recording studios.
In fact, if the Bel Canto is true balanced, then any decent XLR cable should not offer much difference in sound quality, despite the cost.

Yes.. the theory vs real world...I can guarantee some XLR ARE BETTER at low level detail than others. Theory or no theory. And it has zero to do with 'not meeting specs'.   
I have no fish to fry on XLR brand. so not recommendations since how long is not given. Though the extra meters usually cost less than the first for many cables.            
My Kimber KS1116 first meter costs $900 or so. But the seven meter pair I bought total cost was $3,200. instead of 7 times $900. ($6300)

Thanks for the feedback all; appreciate the mention of Fletcher-Munson.

I had to Google and read-up on that..!

Length is .5m to 1m.
