If I had to explain every technical detail behind some of some mods, my competitors would be able to build their DACs even better

so its worth doing.

thanks Stan.

I suspect that resistor behind the reg drops 12V (or 15V) to something like 8V for the 7805 so the 7805 doesn't have to burn off too many volts. As the Murata regs need more volts to work with there's a risk the reg will "drop out" and not regulate properly.

Just guessing....

Its one of those subtle but worthwhile free mods

Do i also have to replace another resistor when i put in the both the 5 and 12 volt Murata's?

. I repeat: remove the resistor behind the 5V reg if fitting the Murata reg.

has anyone tried using this ? http://www.ebay.com.au/itm/Burson-Au...item1c154d6a22
I can get them cheaper as they are an Australian company. I was thinking using this with my gatorized caiman. : )

I always wondered how this would work with Beresford DAC!

I am not only sure how will you conect especaly if you use Caiman and Gator.
Let's us now how it sounds in comparisson with stock Caiman.

i just read a post where Stan said it is not possible due to power mismatching.
