Perhaps interesting to report Mr. Jung's new shunt regulator, there is a book released where about 13 well-known regulators are tested measuring and listening test, someone already read this book?

If it was in prototype and not in realeased version, I am to assume you did not think it added anything to the sound to have seperates?
In fact it adds, but I had to jump from a 3400euro (Vienna-Acoustics) speaker set, to a 9000euro (Triangle Magellan) to get the difference.
So far the biggest Shiga improvements I found are:
- Tentlabs clock
- separate power supply for Tentlabs clock
- changing S/PDIF output resistors to Vishay VAR-Series "naked" Z-FOIL
- replacing L7808 reg with LT1086-adj. Please add a 47uF tantalum over R50
- add C11 - 1nF silver-mica

I have same ESR meter and for organic semiconductor cap over 100uF/50V I get 0.00
Blue ESR is working at 100KHz.
With advancedevices smat tweezers I get other results, but this is working at 10KHz.

Tibi, you know we all have the greatest respect for what you've done 
, but in the items you've listed which have improved the Shoga, can you describe "how" it has improved in terms of its sound qualities, soundtsgaing, articulation, smoothness etc?
I'm worried that at some point this thing is going to get so good that improvements may become subjective.

I said once and I repeat, I´m not the man to comment my own design/product. Sorry, I´m not a marketing man.
Beside this, all improvements are highly related to the system each of us is using and of course, personal taste.
What I can tell you is that I´m usualy looking for better instruments separation, body and clarity, while keeping musicality. I´m also paying very close attention to attack and decay.

That sir, is a good set of standards. Enough to put your comments into some perspective. Thank you.
The cap forming started last night at 8 PM. I was happy to see that it did not explode when I walked away. Voltage across the 100 KOhm resistor went down as expected. It went down to less than ~200 mV within 1 hour. As of this morning it was down to 11 mV. Wondering how far to push it before I say the first phase is done.
Tony,
I didn´t say that BG are not good in this regard. I just only wanted to highlight what specs are relevant and you should look for in case of upgrade.
C62 don´t need to be so fancy. MKP was a handy and pricewise solution. A better cap in that position may by a PIO, same value, but substantially bigger in size.
Also a 100nF/400V PIO in primary side of the trafo can have a great effect. Just try and you´ll be surprised.
C66 can be any value between 1nF - 22nF and I know only few manufacturers - one is Cornell Dubilier.

Tibi, with regard to C66, on the schematic you have it listed as a NPO. Is a silver mica better in this position than the NPO?
Also a 100nF/400V PIO in primary side of the trafo can have a great effect. Just try and you´ll be surprised.
Hi Tibi,
How do you connect the 100nF to the primary side of the transformer? Is it just connect the PIO to the 0V and 220V on the primary AC input of the transformer?
Thanks
