Hello,
According to my information, the Mundorf MCap Supreme Silver Gold Oil Cap takes 3-400 hours to arrive, which is a long journey.
Similar to the Vcaps and probably also Milfex.
Just as a tip, if you have new tubes, take the opportunity to burn in the tubes for 100 hours and then return when the amplifier and the caps have reached the required running time.
My Ultigreg now has just under 60 hours on it and the sound is not bad for now.
For most people who don't play with these things much, it's probably not noticeable.
But for me personally it is a bit.
I can hear from memory that the Vcap is what I want.
But I will tell you that it has been a similar rollercoaster ride.
Especially with the Odam, the first 200 hours were up and down, but it also showed where it was going.
Overall, you really have to be patient.
The vcaps were never annoying at any time, I must say.
The Mundorf, on the other hand, and that's just a personal side note that doesn't have to concern you.
Is that it can be a bit listener-fatiguing.
I changed the pads on the Atrium and it became more pleasant.
Keep in mind that the rest of the content is also new, as are the tubes, so the final sound is not what you hear in the Ultimate.
Another tip for the burn in, don't get the idea of running the amp for 24 hours to speed up the process because of its excellent temperature characteristics.
For the capacitors it is better to let them run for 12 hours and then give them a break and again 12 hours and so on.
This gives the oil enough time to flow back.
This was a personal tip that Vcap gave me at the time.
You will notice that it gets better with time.
Especially calmer and smoother.
After receiving the amp and waiting a long time, the burn in is the last annoying thing until it is final.
That is the only thing I can say at the moment and tips I am happy to share with you.
So patience patience patience....
