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

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!

You could get the Lead-Free upgrade and Master RC Networks(Dueland caps), which have already being proven and go from there without any guess-work on your part.

clabe, oh yes i remeber you now.
happy new year!
what is it about the upper mids and lower treble that is bothering you?
and did you have this issue before you changed all the caps?
i want to hear what you say before i say anything more.
but i know this cap and its sound.
best regards,

Hi Bobby!
Did you get my e-mail regarding whether my VSM MX had X-over cryoed or not. Important if I have to upgrade with Mundorf S/O throuhgout whole X-over or not.There´s a considerate difference in price.
Like listening to clarinett a lot, especially to Mr Putte Wickman, world wide known. Unfortunately died last year in respectable age of, think it was, 82.
Sometimes I can find its sound a bit sharp, it doesn´t mean it have to be speakers. Upper treble I find a bit short, could be my phonostage or other equipment.
BUT, I´m willing to give it a try with other capacitors.
I noticed improvement with S/O in BAM + RC network.
Please I´d appreciate if you could tell cryoed or not.

Many Thanks!
