Notes:  

There is a debate on Teflon and Twisted-Pair cables. Some people think Teflon cables are superior while others think twisted-pair cables are the best. We don't have an answer to this debate. Our experience is that: if there is a difference, the difference is not big enough to tell. These DPT cables are the highest quality Teflon cables. These cables are marked Ultra160. But they are tested supporting Ultra320 well.
