Thinking outside of the box

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

I have a long held tenet and feel very strongly, that revisions, improvement and address of the certain and fundamental limits of the stock power supplies, warrants and very much needs attention. The multitudinous implementations (several dozen) each have show improvement... are all worthwhile. That said I have stuck with beefy, expensive, large, heavy linear supplies.
I am not trying to build to a budget, or even constraints of the chassis. I am trying to advance the performance capabilities to the very highest order possible... comparing (my modest home build) results to inordinately expensive solid state and even vacuum tube gear... OTL amps. This is how I spend my time in retirement.
(at this point) these are using Hafler heatsinks / output configuration (for proof of concept testing) it has been easy to scale each step and compare the evolution along the way, staying with the basic amplifier modules that I have been using for many years.
I continue to hear notable improvements with each progressive step... I cannot encourage enough, the level of attention to the power supply, regardless of whether Linear or SMPS... the circuit will respond, merit the work [if implemented well]
At present, I have 2 supplies, using the Mundorf MLytic HC and *traditional* United Chemi-Con electrolytic. The Mundorfs are .so expensive. However, they are nearly a break through in performance... the best caps, I have tested or heard.

My (stock Hafler chassis) P230 has evolved into the test chassis which is mocked up on plywood (do not ridicule me;) as I wanted to test concept on cheaper material than 1/8" sheet aluminum, as there is a great likelihood of changes in the layout as I evolve with this project...
The choice of 8020 extrusion for mocking up my proof of concept CLC power supplies permit unlimited flexibility to change and easily adapt. The open chassis also permit easy access to work on the piece from any angle, versus being confined to a box.
The choice to test with Musical Concepts PA7 driver PCB / Hafler power modules allowed me to test the CLC supplies, side-by-side the "stock chassis" and amps that I have been using. Working with a known quantity. Admittedly, it may look funky, ill-chosen... It is effective and planned.
