@npdang You're not experiencing what the JCAT is capable of because you're not using a linear power supply. You can buy a budget LPS from Ebay which ship from China or get a high end power supply like the Illuminati V3 from Mojo Audio or a Farad Super3.
I also highly recommend that you purchase or make a high quality DC cable. Cerious Technologies made me an excellent Graphene Matrix DC cable. Zenwave and Verastarr can make custom DC cables as well.
