I’ve looked over various cap labs, seems Mundorf offers at least 6+ lines of caps. Seems this lab has done its homework, and i am very impressed at their web site offerings.
I see a YT tech guy who offers mods, uses ~~Mundorf’s~~ as per clients request ,,of course,,,but i am confident he has no issues fufilling that order.
He posts YT vids on his mods,,and I can actually hear the huge sonic gains in his mods via my $10 comp speakers.
I just had some M SGO (6 white cap/not supremes + 2 Silver Supremes) and I can hear more dynamics which the cayin stock caps, Real caps , blocked via cheaply made 2 cent chinese caps.
I’ve had tech guys, Richard Grey in that group ~~Wasting your money on caps,,,a cap is a cap,,is a cap,,,so goes their mantra.
Well to my ears ~~~at least~~ I do believe i am hearing things not heard with cheap stock caps.
I still have 8 more small caps to employ,,just waiting on M to make that size, the Ebay seller says, will arrive any day,,,it is the .022 cap.
.
Now the mod charge was $250, as it was a pre fab board, and not a easy solder.
Richard Grey said he wouldn’t touch that type of mod..I am very glad I got it done.
Now opens the doors for further upgrades.
I would not be happy addinga new Class A preamp, the Cayin SC^ with cheap caps in the cayin cd17.mark1.
As mentioned I am going all M SGO caps in the
1) cayin SC6 Mark2
2) Jadis Defy(Not sure how many there, as it is quite a few caps,,have to talk with Richard and see where the critical caps are in that schematic).
3) all new M SGO + 2 Spremes Black casing SGO 10UF (they are huge and i picked up a pair at a good price on Ebay,,now i need to add another 8 UF to that point in the xover, so going witha 8uf SGO white casing.
All these mods will takea year,to complete,,as my tube flipping has beena financial disaster = taking a huge loss. That ~~Fiasco ~~ has set me back 6 months on the purchse of the Cayin preamp.
anyway,,back to M caps, I use them, as they seem to know what they are doing, and I am a believer a nice cap will cost ya.
I do not want to go with low priced caps, then years later change them out.
As I say, if we cut open one of the other caps mentioned,,then a M cap, the construction quality might be evident.
We are talking about nuances here, and i am aware a superior cap might sound ~~~similiar~~ toa lower budget cap,,,But think about it,,,folks were sucked into all sorts of ~~snakeoil~~~ past 10 yrs or so,,with ~~~high quality cables~~~ Pinched waist tubes,,,,,getter tubes, Holy Grail tubes,,and all such nonsense,,paying exhorbitant sums for these ~~gimicks~~
Caps are ~~the real deal~~~, Its my opinion, cap mods will become the next biggest thing in audiophile universe.
The old cliche which Richard Grey and other tech gurus *if it ain’t broke,,,don’t fix it*** is old school and that philosopy needs to be proven ~~~wrong~~~
I’ve had personal exp so far with the Cayin cd17,,and look for more huge gains with the other 3 components.
If Jadis installed M SGO caps, the Defy sale price would run in the $$$$$$$$.
Should mention,,,if you are considering going M Supreme’s, these caps are HUGE, and space constraint may be a issue. The lower priced white case caps, are ~~nearly as good~~ and far less expensive>
I think the Spremes are a ~~overkill~~ inspite ofa EU tech guy suggesting the Spremes are the better choise.
I just don’t see the justification spending that extra cash on a bigger cap,,,...
