Alright. Will be interesting subjective consistency if Alex will say the same.
I will like to try some big 10000uf Kemit rifa caps in first part of the Salas supply ,,and place some 150nf foliecaps on output of the supply (i have this parts)
will this in any way be a bad idea

It can turn out to be a bad idea if your diodes are not strong TO-220 and the fuses may need upgrade due to stronger charge inrush. For 150nF shunting caps don't know, sometimes they create a peak with other caps. This PSU ain't reactive, has no error feedback loop amp, that's a major difference from other really active regs you may try there, its also very low noise and has hundreds of kHz bandwidth flat Z out. Thus it will not react and oscillate but maybe bypassing is not the same in effect like in other situations. But this one you will evaluate for yourself.
Ok i see the point....may need some slow start to work,,,i will think about it,,have no slow start on hand
In all accounts don't try two changes or additions at the same time when you evaluate mod parts ideas subjectively. They will mix and you will not learn their individual utility.
I am buying load resistors to test my SSR3 PSU-pcb before live operation.
When the DCG03 is ready, I want to test it, too. What resistance values ( r, watt) are meaningful parameters?

That answer was for double mono. If with a common supply for stereo you will need two 120 Ohm 5W dummy load resistors in parallel per rail to test it before live operation as you wished.
Hallo Salas
I will use 1x DCG03 and 2x SSR-3 PSU to deliver a stereo Headphone and RCA signal.
If I get you right the Requirements for the power supply unit are 10W per channel with 100mA bias and less with 150mA bias. Is that correct?
Two test the DCB03 I need a 120 ohm, 5W resistor for each channel, right?

just now tried some rolling opamp...ad823 opa2134 TLE2072
for now i prefer the opa2134,,,give something to the sound i like,,will play some more hours to see if it stay that way
the ad823 and the TLE2072 is more or less the same,,there are some difference..
will tell more when i have played much more on them

That's double mono PSU configuration then. 10W per channel peak power draw with 150mA bias and 7W with 100mA bias. Because it can swing double its bias current before pushing hard on a heavy load clips the negative portion of the sine wave. So one 120 Ohm for each rail on each PSU when you want to set them and test them before going live with the preamp as load, yes.
I know of one guy with big speakers and rather heavy room sound that the 2134 in the DCG3's servo gave him what he wanted that is why I urged you to try it too. Makes more tonal contrast and a spicier top. But in my experience when the transducers are allowed to come across neutral enough the 823 is the more naturally refined and spacious one. The TLE2072/82 made the more forward presentation with impressive slam but it also had the less refined treble among those three.
funny, by me is the opa2134 the most spacious..and with very good tonal contrast
just heard Buddy Guy live Montreux on dvd...he started with playing alone on his guitar-
just about the best sound i have ever heard,,,

System's synergy. That's why I left a window for you guys to roll. The 2134 fulfills all the technical requirements for that position, no danger precaution flag raised by me. Happy to know that I helped you go on right track by recommending it for a test.
Others hear nothing or almost nothing between different chips in the servo as repeatedly stated here, one other went full circle back to the 823 even after a much expensive discrete op-amp test also. Just keep whatever technically correct type makes you happy in your own system with your own ears.

i have heard that discrete opamp not are the best in servo,,,is it something with the use of jfet in normally opamp ?
sometime in next week i get my trafoes,,,maybe 2 trafoes also make a diffence..
many things can be done to change sound,,,cable from usb ..signal and so on
