Yes, Chris VenHaus is very knowledgeable on the CAT 5.

I replaced AudioQuest Midnights with Cat 5.I used 4 runs of it 2 pos 2 neg. I use it in MY HT set up.
Economy of Scale. If I where to sell this CAT 5 Commercially, it would sell for over 300.00 Very labour intensive to make and I used Cardas Spades.

If you are a DIY and have 5/10 hours to kill go for it.

Single runs are better than average cables but if you double up twist them shrink wrap and use good connectors they are very good..
Plenum grade as a Minimum.
