Hi all,
photos show was the ultimate ver.3 TDA1541a w/USB2.0 receiver.
ultra power supply with 9 section too. Very low noise, I use headphone & earphone to test already.
This is funish look, but all the parts was cheap one, when mass production will much better.

Hi all order diyers,
Before I post the dac, I will groups totally how many DIyers lov 627, how many diyers love 797.
don't worry for this.
U wll get this happy.
Pls all prepare one 16~0~16V 35Va power trans on hand, don't use round core, not good.
RS had some isolated small power transformer 110V X2 parallel two side
110~0 110~0
16~0 16~0
two winding was sperate two bobbin to isolated the noise.
I had try to ask for factory to produce. price is good for one USD 10.5 per one 40VA, but worse was the postage. so I forget this.
also use copper foil to double shielding is reeally good.
The sample I test was quite good. I use headphone & still hadn't heard any noise.
thx

That would be not easy 16V isn't a standart value here for secondary winding of R-core trafo. We have 0-15V than 0-18V for next step.....The only solution I see is to go for an extra trafo in a factory, and than it will be à EI trafo. Ring will not be suit has i read it.
Marc
hi marc,
U can try 15~0~15 first,thats enough. I was worry the input voltage of your home is really arrived the really voltage, such as 0~220, actuall is 0~207~210. so I choose 16~0~16 will better.
So not worry for this & ty the power trans in your hand first.
hi dw8083,
pls visit this line to take a full look of the ultimate ver.3, include USB receiver, the Balance input was seperate another pulse input trans exclude the other input such as rca & BNC, its a really balance input, not SE.
http://www.imagestation.com/album/pictures.html?id=2105567327
this is a full assemble kit.
Balance output looks must use transformer output or really parallel DAC with 4 IV will have real balance output stage.
thx

hi dw8083,
Are there balanced outputs in v3 or plans for balanced out in the future?
