To wire or to not wire power supply sensing terminals???

2008-10-01 by JohnLeightonRice

In a DIY power supply thread on MUFF's forum here 
http://www.muffwiggler.com/forum/viewtopic.php?
t=1200&postdays=0&postorder=asc&start=30 (look for matthias' first 
post about half way down) it was suggested that power supplies like 
the PowerOne models that have remote sensing terminals should have 
those sensing terminals wired up to the appropriate output terminals 
to make sure the output voltage is always the same when the load 
changes (adding or subtracting modules from the system would cause 
this I guess?) That way you don't need to readjust the ps trimmers 
after each change?

I'm looking for second opinoins before I go ahead and do this. 
Someone said that MOTM power supplies don't have the sensing 
terminals connected and I also noticed on Richard Brewster's site 
here http://pugix.com/synth/portable-rack-cabinets/ that his DIY 
power supply doesn't have the sensing terminals connected either.

If you look at the power supply pictures on the Synthesizers.com site 
it looks like they wire up the sensing terminals.

So, is one way better than the other? Are both equally 'good'? 
Thoughts and recommendations appreciated! ;-)
