please, don't take my nonsense (believes) that seriously... just take it as some sort of "war report"...
there are so many things unexplored in HiFi, and especially within the digital area, that we here practically learn "more" from day to day, and as it comes out, to our ears mostly to the better...
but what is really "new" to us, is - while exploring and researching - the absolutely unexpected addition to face and to get used to and to understand (if possible) and to handle "mathematically-physically impossible-" and "nonsense"-phenomenons within the Os and 1s-area which have (so far uncontrolled) influence on our sound...
it is not at all my intention to generate, spread and/or bother anybody with my "personal belief", but I have to face exactly these facts just as they are, and just like everybody else...
"Informations are prerequisite for qualified decisions", so, if one makes use of them to take advantage of, is strictly personally and up to anybody, but anyway, being "informed" is much better than not being informed with the need to believe, if one is interested...
and it's further up to you to take "quoted" results of qualified persons with a scientific education as physician and/or electronics engineer as a "belief" or not, but at least this opens the possibilities for you, if you should want to, to try out certain things for your own purpose, and I always will be glad to "offer" our results and to get to know the ones from others...
regarding belief, to illustrate precisely what I mean, here is an example, someone on the DIY-site wrote:
"Come on - do people really believe that data can be delivered very good or not so good through an USB data cable?? That is complete nonsense in my world.
Either they come through the cable intact, or they dont. "

"I thought the same till I really compared. Has mostly to do with grounding I believe"
http://www.diyaudio.com/forums/digital-line-level/224108-nos-192-24-dac-pcm1794-waveio-usb-input-91.htmlas I happened to be part of exactly that specific experience this, for me, is not a "belief" but a result, no matter what caused it... and as hardly anybody can tell us about these phenomenons, we, wherever we can, try it out for ourselves just not to believe but to establish...
...
and when it is written like that, then I have to "believe" at first sight, but in a second step I try to "verify" for myself resp. ourselves (because I am not alone, I am mostly in a "group"), and so I invited that guy to share and show and make us listen to his (presumably fantastic) results with the shunt regulators, Tantalums and so on...:
"Hoi Doede,
This is something that has been tested and measured by Guido Tent.
We have done this before on other dac units.
I have not done A-B testing on this detail.
It makes sense though; the sunt regulator is much faster than an electrolytic.
The shunt acts as a very fast capacitor with high bandwith and large current capability; that is a combination you cannot find in capacitors.
So you do not need the capacitors any more, they only give more work to the shunts with their interaction.
In comparison to a series regulator the shunt does not only source current, it will also sink current. That makes the power lines much more silent. Imagine all the current that is bounced back from a consumer when the impedance rises, this current will stay on the power lines and can dissapear only in heat........
Regarding the wima at the dac pins and the one on the shunt: yes it is better not to use two wimas and mount the shunt directly at the dac pins. But as for this design the shunts do have some distance from the dac so it is better to keep the extra wima..."

or other things, where we came from an idea/belief/presumption or a simple wish to try something out to concrete results when testing practically
"...this told us again, that BIG power supplies do make a difference...
also, that paralleling DAC chips seems to have no limit..."
http://www.diyaudio.com/forums/digital-line-level/224108-nos-192-24-dac-pcm1794-waveio-usb-input-108.htmlso, this clearly shows that even the professionals have to experiment and listen for themselves, even if they have to overcome with what they have studied and have to face to try out practically...
...
most of that what I read on the DIY-sites I have to "believe", and in some cases we will be able to "verify" the results for ourselves (or not)
well, on April 5th we will see/hear what it is all about regarding specifically that topic with all those shunts and Tantalums, and if their results and our "believes" come true...
presenting and discussing all the results of all DIYers in the net all around the globe to me is one of the best things that could ever happen in our time...
...but I learn to get the results "neutral" it might perhaps be "better" to leave future reports then to our guests...
aaahhh, lastly there is some good news, a "fact", not a belief:
"384kHz with waveIO Runs without Problems on the dddac..."
