The Infigo USB costs $1,600 so I guess it would fit the higher end systems. The Wireworld Platinum Starlight 8 USB at $600 is a fraction of the cost so I can understand the Infigo is better. Nevertheless, I am amazed and shocked that the difference with USB cables is noticeably huge, and the performance of the WW Platinum Starlight 8 can still be improved. My early experience with cheap USB cables around $100 and some $5 and below freebies, they all sound almost the same to me with negligible difference.
The WW platinum Starlight 8 replaced the Tellurium Q Ultra Silver that I was using for the past 2 years.
