From your reports I know you as an experienced audio enthusiast. Still I'd like to add one remark, you'll probably be familiar with.
The cable itself does not make music, of course. But: the effect of capacitance may vary from slight high roll off to subjective low emphasis. If one is 'in need' of loud lows, one might favor the 'sound' of the lesser cable.

Experienced? Kind to say but I am in my early years of serious audio.

Of course the cable does not make the music, it can merely get in the way by subtly distorting it. When I heard the silver one my system was terrible compared to what it is now and maybe it just wasn't ready for it. Also the Neutrik Pro-fi plugs may have contributed to the poor result. At the time a good wire was a £30 coaxial with probably polyethylene dialectric. Now with this solid core and good plugs I can decipher lryics that were previously unintelligable. Very pleasing.

If I may say without "sucking up" you really seem to know your audio Jaap!

Simon

Can't you find any PPS caps? For bypassing polyester is not ideal.

Thanks Simon, you can wash your arm now

Really, the transport from source to amplifier gives birth to the most overrated products. It only needs three or four simple wires, no plugs and an old sock. Commercial products coming near are Vandenhull carbon cables because of their stiffness as movement of wires degrades reproduction slightly.

Be aware ultra low ESR brings instability for most three legs. For fast transcient response you might try bypassing the reg with solid Tantalum (20-30uF) but some reported extra noise... Have a try.
A fellow like this ?

The FC aren't ultra low, just low.

lol, erm, ok, arm washed. VDH seem ok (D102mk3 is smooth) and I was impressed by the lack of grain listening to Chord Signature (but I don't feel it's worth £500, very silly price). My Kimber Crystal-Cu is good, but probably not as good as this home-brew.. I will think about rewiring my preamp next, and possibly Vampire OFC copper RCA sockets on Marantz and preamp. Ok, no more wire talk from me now, I know it bores some people!!

Can't find anything when typing "0,1uf PPS" or such on farnell website, nothing looks close the red Wima you ever showed me on picture... :'(

On these pics, the red Wima cap is written "0,033, 63 A, Wima, V9". Does it mean anything to help me?

I think you'll bann me very soon for making HF noise in the topic...

edit: any ref for these ??

This is what I made for PSUs.
There's a 39mH common mode double inductor between the 1.000uF caps, Schottkies, Micrel 29302BU (Mouser USA).
For 29302 you better order the TO220 type, for fitting on a heatsink if you aquire larger currents than 50mA. It's a low drop low noise reg. I bought a bag a couple of years ago. Maybe the design is bettered these days.

Originally I designed them for the 1G4 tube setup, complete with handwound tranny.

This is a Tantalum electrolytic capacitor. Usefull for fast transient response noise filtering behind the reg. Black Gate 0.1uF NX series give even better results, imho.
