Hi Martin,

You will hear an improvement with the SR7EHD compared to your SR5. It’s not just the transformer that has been increased in size. The rectification has been altered to a balanced arrangement allowing the transformer secondary to retain it’s ground reference even when the rectifiers are not conducting. The energy storage capacitor bank has been increased and the supply rail for the output stage control circuitry has been improved.

Marco heard a substantial improvement with the SR7 over the SR5. You should hear this upgrade with your power supply even though the internal regulators have been applied. It might not be to the same degree but it will be significant.

Regards
Paul
