can we lower C2 value to 470 uF If we use to supply analogue loads
My subjective best choice for analog was useing Mundorf 4pin AG+ 1000uf cap. In the post I described how to connect it. For digital I used Nichicon FPCAP 1000uf.
I experiment with lowering the value of C2 down to 100uf and using polypropylene cap, however results were not satisfactory for me.

Yes if your CCS sink does not get too hot

Has any one tried 2SK880GR instead of 117GR? Any difference in performance? Thanks.

I tried 2SK880-GR but in BiB. They are OK performance-wise and I did not notice any sound degradation. If you are wondering just go for them

Hi, Tio

I am thinking to use Mundorf Mlytic AG+ in C2.

I suppose in your connection, you lift the LEDs off ground by employing Mylytic's separate charging / discharging circuit (kind of decoupling). However, it looks like we should use in+ and in- to form a loop and then out+ and out- to form the other (decoupled) loop. Your connection seems to be different than Mundorf's description and than the connection on Salas' flexy. Could you double check?

Thanks.

Among many caps I tried here (elna silmic II, black gate Std, Elna Silmic ARS, Nichicon FPCAP, Nichicon muse BP non polar ...) Mundorf 4 pin are of the widest audio bandwidth (especially high frequencies are very clear and deep bass), best resolution and clarity. You connect your LEDs between Out(-) and In(+) pins then In(-) to GND in PCB and Out(+) to PCB + trace. You would have to just modify/destroy your board in good way to fit this cap or you could wait until Salas releases Reflector-D Mini Flexy version, some day, maybe . Anyways it is really worth mod.
And as you already mentioned give some time to burn in.

So, for digital part of chips (DVDDs) I am using Nichicon FPCAP on C2 position (best 1/f filtering, but terrible tone). However for AVDDs, analog Vrefs or powering resistor ladders dac directly (Soekris R2R), generally places from where audio signal is produced from, Mundorf 4 pin I found to excel any other cap in this position.

The description you provide is for case when 4pin cap is used in PSU application.
The one I described is for LEDs filtering. It is tested and works. I got few reflectors working like that. I cannot imagine connect it any other way for LEDs.

Does anyone have spare regular (not mini) Salas Reflector D board to sell? Please PM me if so.
