Caps upgrade in the NAF amplifier

I am contemplating an upgrade to my NAF Legend-II amplifier (replacement of 0.47uf coupling caps).
1. Are V-Caps and Mundorf caps similar (in terms of dynamics, transparency, sonic signature, etc.) or they have nothing in common?
2. The NAF amplifier has PCBs inside. Is it a problem for a newbee to mess with the soldering iron when caps are mounted to a PCB? Is it a problem in general to unsolder the stock caps from a PCB and to solder replacement caps to a PCB?

Thanks for recommendations.
