Hi Simon,

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! :cool:

Thanks Simon, you can wash your arm now :D

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.

I really mean MILLI (1/1000) Henry. The purpose is to filter the ripple and mains pollution. You'll find them in old computer PSU's, mostly Murata dual coils with iron center. If you order new they are less than 1 euro each.

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!!

diélectrique:polyester

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


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.

Look for the brand name Rifa. It's carried by Farnell.

While you are at it, order four 39mH double coil Murata inductors (je ne connais pas le vrais nom en Francais).

Thanks for answering!
but...
I think I've just discovered that PPS stands for "Polyphenylene sulphide"... wich are out of stock with no offered alternative!
This is my fate...
http://fr.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=3891010&N=0

And what is the Murata stuff for?
For 39mH inductance they only have a Toko one... out of stock!
http://fr.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=148875&N=401

Maybe tonight is the night I suicide! ( I know many wants it so much!! ;) )

... maybe the 36 or the 43mH dbl Coil Murata http://fr.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=9528504&N=401 will fit? What for? A chimney? :)

et ton français me semble très correct !

Merci. (not hinting at killing yourself :D)

To answer your what question: it would save you some time getting the components, as it seemed you were ordering :whazzat:

Honestly, the PSU quality is important for good reproduction. You might experience it in a later stadium after doing the mods you are planning. 36mH will be fine too, look for the least resistance but current capability of at least 150mA. 1.000uF Rubycon ZLH are also sold by Farnell. Get some stock, they're good caps and not too expensive.

It's a good thing you search for yourself. If Farnell is out of stock, they might receive the items within days, just ask.

I have acd67 & some nx 0.1 cap can you tell me the exact plce to put on the player because I have no electrical knowlege

[this calls for a silly joke but I can't think of one]

Amigo,

Without knowlegde it's very hard to complete any modification whatsoever. The players electronics is delicate and can be ####-up in no time from the heat you apply. Furthermore, adding a single 100nF bypass cap makes no major improvement.
