Default Polypropylene capacitors - axial or flat plate?

Hi all,

I'm just wondering whether it would be better to use axial (rolled) or stacked flat plate polypropylene capacitors for the output caps in the preamp I am making. All the "audiophile" caps out there appear to be axial capacitors, but I would have thought the low inductance of the stacked plate caps would be preferable. What the the advantages/disadvantages of both, if any, and does it really matter?

In case I am not making sense, here is a picture of the two types I am talking about:

Your advice is appreciated.

What I know is that the "stacked" Wima MKS2 sounded crappy compared to the "axial" Solen MKP, and even the stacked Wima MKP4 didn't sound as impressive. I'm talking of all-round transparency

I did wonder too

With extended foil construction, as in any modern cap, it doesn't really make a difference. The inductances will be pretty darn similar.

Foil versus metallized can be important, depending on the specific application.
