The power supply in the latest version is much simpler to save the space (CLC). I believe this resulted in a bit muddier bass. In the first version it was cLCLC. But the difference is very subtle I would say. Maybe as Salas said there were/are some parasitic capacitances.
I haven't done any testing yet btw.

There is always parasitic capacitance in layout styles but I wonder how different between each p2p build and the specific board.

It maybe changes the input capacitance or second stage's Miller effect a bit. If there is measurable difference in the response between p2p and board builds it can be adjusted by tweaking C3 value.

But that is in the same area of how much treble preference also. Other changes between builds like in the PSU configuration may bring differences of course.
