Thanks for your comments.Glad you love your system. My first PA 7 power supply capacitors were upgradedĀ to 4x72000uf of capacitance.then the second one to 4x 42000uf capacitance. A lot of reserve.The inductors were also .upgraded as for the resistors.Even if my room is small this system outperform many systems much more expensive.
The power lock also helps to the performance of my system.
