I'm considering a regulated power supply for whatever my next amplifier ultimately turns out to be. My last amplifier (early JLH 10 watt SE) had a small buzz in the speakers which i reckoned could be removed with a regulated power supply - this became an "accredited" solution to the later revisions to the amplifier.
I have heard that regulated power supplies tend to reduce bass extension and generally strangle the soundstage a bit, but after reading Nelson Pass power supply article i thought about how this might be eradicated with some over-speccing of the supply.
I'm contemplating using multiple LT1084 regulators, each preceded by a 58,000uf capacitor (because i have lots available) and another 58,000uf capacitor connected to the output closeby the output transistor array.
I'm hoping that the capacitors downstream of the regulators will be safely charged via a current limited supply (max 5A) without the regulators shutting down (anyone have any experience of this?), not decided on how to limit the current surge to the pre-regulation capacitors, possibly a relay/timer/surge resistor combo.
Is this worth doing or pointless given that class A SE amplifiers are fed from a CCS anyway?
