What is the difference between SuperCat and SuperCat 7 cables?

Both cables are the same diameter. SuperCat is more flexible and has an overall braid shield. The twisted pairs offer excellent crosstalk rejection and is an excellent choice for stage cables and applications where a durable flexible Cat cable is needed. SuperCat 7 is double shielded Cat7 grade. SuperCat 7 is slightly less flexible and an excellent choice for high noise applications and analog applications where high level and low level signals will run down the same Cat cable.
