In Reply to: RE: TOO MANY Elna Silmic II caps?... posted by Baki on June 15, 2016 at 02:20:45
Well, when I recapped my Revox CD player, it was my first recap job, I didn't want to mess around with the design..; there was electrolytic caps as output coupling caps, so I put Elna Silmic II in that location as well.
I left them for a while but there was something not quite as clean as I wanted in the treble; following some forum tips I then replaced the single silmic cap with two of the same value in back-to-back disposition (-++-) to simulate a bipolar cap and got some noticeable improvement; I didn't compare with big expensive film caps but to my ears it sounds really great, better in fact that my other CD player wich uses small film caps as output coupling caps.
Follow Ups:
That small film caps are most probably polyester ones and they are average sound wise.
Two typical representatives of metal film caps are polyester (often labeled as MKT) and polypropylene (MKP).
Rule of thumb IME is that MKP is (much) better than MKT but it is also relatively bigger in size.
You don't have to spend too much in order to acquire a good MKP capacitor.
I have already mentioned WIMA MKP10 as an relatively compact radial cap.
An affordable and relatively compact representative of an axial cap could be Mundorf Evo Aluminum+Oil (2.2uF - 25mm W x 21mm L). You can find it inside Rogue Audio Pharaoh much praised amplifier.
Even back to back elco could not compete with some good MKP cap.
But, YMMV.
In the case of this preamplifier, I doubt there are any elco caps as signal couplng caps; I don't have the schematics, but I see many red Wima caps on the board, I suppose those are the ones the signal goes trough. But without the schematics I cannot be sure.
