BAT VK-55: cap upgrade

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

Huge difference in my Thor t1000 linestage..Much more transparent and inner detail,along with a more upfront and lively presentation.. Mundorf Cap upgrade details @ Thoraudio.com ....

I put the new V-CAP CuTF caps in my 150SE monoblocks (total of 8 caps) (previously had the TFTF caps). Oh my........!!

I recently used Sonic Cap Platinum(teflon) caps in a preamp upgrade, it was a big difference over the Auricaps that were previously installed.

Thank you for your opinions; is there anybody that has direct experience with BAT VK-55?
