Has anyone tried different coupling caps in the ZEN amp?

These are prob. the stock caps [the black ones are Solen], but I don't know for sure.
Who can shed some light on this?

There are a lot of "exotic caps" on the market, don't know where to begin actually if I want to try out other caps. I once read about V-caps....has someone tried these out? Thanks, Nico

After buying and installing the V-caps CUTF I only wish I done this earlier.
The difference may not be so audible in every setup, but in mine it is.
Since I like a "less is more" approach, my system is very simple and very sensible for small changes ; this is defenately one of them.
Regardless what is said about the long breaking-in time, already there is more air around voices and a more natural timbre with strings [for starters].
I had a lot of doubts about any "upgrade components" for my SE84C but it has been a good decision to go for this one IMO.

After two days of continous use, everything sounds more natural now then before.
From voices to drums, guitars, you name it; it sounds more like "actually the instruments and performers are there".
I know the normal [already very accurate] sound of the ZEN very well, so it's a surprise to discover that two caps can make such a positive contribution to the sound, instead of changing nothing [like many people tend to believe].
Just wanted to share.
