What are the top 3 USB cables being used today in reference systems?

The new Curious Evolved is a lot more expensive.

Was not a “cable guy”. Just didn’t believe that cables could make that much of a difference, especially a usb. It’s just 1’s and zeroes, right ?
A local dealer gave me a Kubala-Sosna emotion usb to try out at home. I was truly amazed at how it opened up my streaming front end. Not joining in on what’s better, but in my case there’s a great improvement with my kubala usb. (Yes, I did order one)

I have heard a lot of cables and owned many usb cables  
the Final Touch Audio Callisto  USB cable is very reasonable at retail $850 
is a Great cable Never have I ever put a usb cable in that was like a good component upgrade against the wire world platinum 7, and Lightspeed 
neither had the realism soundstage width and depth and rich realism .
Lampizator US is the distributor.  Read the reviews online ,and then check it out 
 they may even give you a week to audition it , a They don’t tell you what makes it special but  to my knowledge the Only ones Thst sourse a special Copper 
with a minimum of both Silver,and a Gold content  which is very limited
then Hammered to the diameter which also changes the grain structure like a Katana sword, nothing else is disclosed . This in my opinion is why it sounds so 
special from Any other USB  cable I have Ever heard .Well worth  checking out.

To those who do not believe a cable makes a difference, I ask you what properties make any component better than another?

Or I ask you to describe the difference you hear between one component and another?

For the engineers I ask how far can you see into an electric current to tell if it is good or not? If you say oscilloscope, then I say look at your zeros and ones and notice if there are 90 degree angles. 

Also Lampizator are great DACs. Maybe not for a system that already has a bunch of tube components, but for a solid state system like mine I like them a lot and I have had more than my fair share of DACs over the years. 
Rob from Lampizator North America is great to work with and he will even see to it that a DAC you order is customized to your specifications too. Plus, what other DAC company will take one of their own as trade at full retail price?

I can vouch for and highly recommend the original Curious.
Have used it with a Chord Qutest first with a Melco N1A and more recently with a Roon Nucleus.
Been well reviewed from the likes of Darko, HIFI-Advice and Audio Bacon.
