Thanks for the question. Suggest you read through posts 1606 to 1611 in this
thread for some answers. But briefly, you size the power supply and design based on the needs of the design, whim, your budget, and chassis size. I am certainly not allergic to using large toroids and large filter caps, etc…but there are courses for horses.
Here is an
example of where I went nearly all out in the traditional sense, but then again, this is for a very different amplifier build.
You can certainly build Leo’s design using a toroid and large sets of capacitor banks, nothing wrong with that, whether it is needed is a very different question. Think about the PSRR‘s needs of the main amplifier design first and then redesign the power supply accordingly.
In example, I have a colleague of mine who has an excellent sounding Neurochrome Modulus 686 using switcher supplies. I am recasing my Neurochrome Modulus 686 at this time but using a linear supply. For sure mine will be heavier, bulkier, and more unwieldy. It won’t measure any different. But will it sound better? To be fair, we should put a couple of bricks on top of his as it weighs < 15 lbs!
Best,
Anand.
