Default Mic preamp

Hello,
This is a superb preamp from Samuel Groner site.
http://www.sg-acoustics.ch/analogue_...eneroso_r1.pdf
I wonder about the size of the C105 and C106 capacitors.
I saw two huge size caps on implementations using this circuit where they are much larger than shown on Samuel Groner's PCB.
I mean physical size ( not the 33uF value ). They are 33uF 450V caps.
Because this implementation, is from a mic guru, I am sure there is a good reason.

Do you know the reason for these oversized capacitors ?
