MOTM

I am at the point where I should consider buying a another power
supply for my modular.  At the this point in time, I don't have any
modules that require 5V, nor are there any MOTM modules currently
available that I am considering that require 5V (I already have a
MIDI-to-CV converter).  I'm wondering if I should get a triple supply
that provides 5V or another supply that only provides -15/15+??

Is there any disadvantage in adding a separate 5V supply at a later
time??   Further, since it isn't used to power the signal path,
is there a disadvantage in using a 5V switching supply??  They are
much less expensive than 5V linear supplies.


Also, while I'm typing, does anyone know why the Blacet modules use
such a massive amount of bypass capacitance??  The MiniWave and
TimeMachine have ~270uF and ~320uF respectively, using two 100uF caps
and a bunch of 10uF caps, with very few smaller caps.  Does anyone
know why that is??
