Use an isolation platform that has air in it. In addition I use cones from black diamond. As far as power cords go the Joule loves "FAT MAN" from Electraglide. As for tubes, you'll have to spend a LOT of money to buy better tube than Jud uses from the factory. Although the 100 and the 150 pre amps work well with almost all high quality power amps you must hear them with one of the amps from Joule Electra. Enjoy
