Experience of Mundorf S/O or S/G/O in Merlins VSM

You might ask Dgarretson or Sns they should have some imput for you.

Here is a site that gives a mine of info on caps and other things.

Thanks guys!
Dgarretson use Clariry Cap MR in his speakers, know him since earlier.
Humble Homemade, I´ve read the Cap Test but can´t make up my mind.

i responded to this yesterday but for some reason it did not get posted.
depending on the version of the vsm you have (which is?), it may not be good to mix the capacitors. the later vsms use cryoed hovlands and the use of a non cryoed cap in the hf may make the speaker sound incoherent and lacking continuity.
you will certainly make the vsm sound different but not necessarily better.
changing the caps in the rc network or super bam may proove to be a better way to go because these caps affect the entire bandwidth.
i am not advocating the changing of the caps but we are using the duelunds in the master bam and master rcs with to great effect.
thank you,

Thanks Bobby!
My VSM MX I believe is made 2004, serial no. 3468. My BAM- RCA was made 2007.
If possible I would propably change to S/O that would make it easier (read cheaper) if I have to change the rest.
I will also use Duelund resistors instead of MKP, already use them in RC network together with Mundorf S/O.
Already have S/O in BAM together with Vishay bulk foil resistors (0.01%). To be honest I´m pleased with sound but I want to know if it can be improved in especially upper midrange and treble. Beeing a bit of an "audiogreed" I search challenge for improvement it´s part of enjoyment.

Kindly Regards & Happy New Year!
