BAT VK-55: cap upgrade

Hello,
I have a BAT VK-55 power amp and it is a very good amp. I've read about a very positive upgrade changing the original caps with V-Cap or Mundorf. I would like to know if anyone made this modification, which type of caps used and the result obtained.
I'm new on this forum and have limited experience with equipment modification, so I really appreciate your support.
MANY THANKS

I have no experience with BAT amps, however I have upgraded many coupling caps in tube amps and preamps.
Vcap or Mundorf Silver/Oil caps will sound much more transparent than BAT's paper-in-oil (PIO) caps.
If you like your amp's tonal balance and transparency, I do not recommend changing the caps.
If you could use more see-through transparency and midrange/treble refinement, Vcaps and Mundorf are excellent choices.
Another option that will not change drastically the tonal balance but will certainly improve refinement and timbre are the new Vcap copper/teflon caps.
i hope this helps
