Platinum upgrades by SMC, including upgraded Plitron transformer, and Jupiter bypass caps. Freshened up by SMC in 2016.
Full range signal fed directly from DS2 to McCormack, which then feeds the modified H3 passive crossover.
Best SS I've owned. Mid-highs would rather be tubed, but large room + low 2.7 ohm dip in H3 impedance prevents their use.
