I use the Mundorf 4-Poles all the time.

Joachim said he likes Mundorf AG 4pole. Used Sikorels in second build for brother and noticed change over Nichicon KG, but we are getting into the black.

DDR (Diode Diode Resistance)... a FdW terminology... the two diodes are in reverse.

Black ? What do you mean ?

The simplistic is prone to be affected by the simplest of things.... Even caps in the rectifier board can produce outstanding differences... this is not new to some of us.

Do you need Sikorels ?
I have access to 1000nds, NOS.
I did not say that i like the Mundorf 4 poles, i said that i use them all the time.
I do not " like " parts in general. It is the way i use them and how i try to get the benefits that particular part has to offer. I know, this is hair splitting.

I agree with you.... we do not need to "like" parts.... we need to know how they behave so we can "cook" the right sound in the end.


I am quite pleased how the NOS CCCP teflon caps perform in this last build

My apologies. I should have said you mentioned them. I would love some, but price has gone through the roof. I got the 3.3mF that I currently have at a reasonable rate. A guy on Ebay bought he rest of the sellers stock and tripled the price.

@RCruz
When I say black, I mean the subjective end of audio. I agree with you as to the effect of parts, especially in a design such as this.

With the Sikorels you can do a little trick. Take two of them and put a 0.22 Ohm ( that is for a 10.000uF cap ) resistor between. That way you can roll your own " 4 pole ", not really, but it helps the ripple rejection quite a lot. For smaller cap values you can use bigger size resistors. Make sure that the resistor does not burn too much voltage and has enough wattage that it does not get too hot.

That is a very good tip regarding ripple supression... but in this case, and using this type of shunts, I found that CRC somehow muffles the sound.... similar to using a mains filter (well not so much)....

Good rectifiers followed by simple caps always produced the best results for me... Once I put two 4 poles in series and the result was really bad....

I only use CRC when I need to drop some voltage.... but I really do not like the result
