I look forward to seeing this product develop. Will be great to have a power supply for the Bitzie.

It's great to see things are moving on. Looks good to me.

And now....

Populating the board and starting with the surface mount power management stage which is ridiculously difficult to see without my eyeglass (used to have 3 but can't find one...)

power-supply-management-ic

The small one is the IC and the big one a 9 Amp MOSFET!

Length of IC is 2.9mm, less than one eighth of an inch, and a complete ******* to solder.

PCB artworked and now awaiting the prototype board(s) from the UK manufacturer. As good old Kirchhoff recognised that signal current flows in circles I thought it advantageous to squeeze in the highest voltage reservoir capacitors as possible. The reason being that low voltage capacitors don't have the capacitance stability that high voltage ones have. This means that high signal frequencies see a different capacitance to low signal frequencies, and certainly in analogue the difference can be heard. Digital may be different, but we'll see (erm, hear).

From your comments Phil, it sounds as though you're ahead of the game.
As Graham notes in his introduction, one thing that we here should all have come to know is that a good robust power supply lies at the heart of any decent audio device, whether it be digital or analogue.
Just listen, if it sounds good to you, enjoy it.
