A Joule Electra LA 200 replaced my CAT Sig MKII (I have two systems, one with Joule, the other with Supratek Syrah). Tube regulated power supply on board (as opposed to CAT SS with umbilical), easily superior harmonics, voice etc. CAT had horseshoe-shaped soundstage beginning at speakers and extending back; Joule extends wider and envelope of sound reaches out to listener. Put an NBS IC on it with a big PC (Electraglide, BMI Whale) and save yourself a good chunk of change. (Joule goes for $1500-2000 used. Get the MkIII)
