Dreaming of a DIY 8W Class A amp designed by Nelson Pass?

@lewinskih01 - nope, I have not. It was just one of the few linear power supplies on ebay that did 24V at 5A (which is what the Amp Camp power switching supply is).  I have tried a few different Teradak power supplies.  I generally try to get a PS that has many smaller capacitors in the power supply to reduce ESR and provide a faster response to voltage draws.  These have been for transports and HDMI video processing devices (such as Lumagen Radiance and a HDMI KVM switcher).  The Teradak have done an excellent job at this.  I suppose for the Class A Amp Camp kit, two large caps in that power supply would be just fine.

@lewinskih01 dual mono is really the way to go if you can. Each channel/board performs so much better when it's got it's own power supply. In my chassis I've got an f4 board on one side and a sissy sit (diy sit3) on the other. Left them both powered and just shorted the input on one side to do evaluation. The SIT amp got so much better when I finally unpowered the F4. Shocking really how much just having an amp pulling unchanging idle current off the shared power supply could impact the sound. 

And I found the exact same thing with the F4. I had built full mono blocks and was paralleling my inputs and outputs to double the current available to my speakers. Again, the sound improved when I went back down to a single board with it's own power supply. Didn't need the extra power at all. 

thanks for the input  @cal3713  and  @auxinput
FWIW, I wasn't thinking about these for powering an amp. Actually to power an audio pc or a DAC. I have a lab lps and can use a relatively inexpensive, decent looking lps if it performs well. I also liked they have several voltages to choose from.

Which is Pass' whole point, simpler is better.

An approach others have taken one way or another. CJ with their PV preamps for instance, and single driver speaker designs.
