I've been making sounds for the benedini - ibu2 -ibu3 and the latest Clark TK60 . Atm I have not owned ore made sets for the ASP ore the Elmod Board .
So , and even if video's don't do the Boards any justice , I'll include a few of my sound video's first.
Benedini.

I don't do batteling and mostly I'm a backyard driver . for me pri1 is how well the Board is on transitions on each soundstep , it has in a way become a hobby within the hobby for me to fiddel with makin soundset's
Other , is the ease of setup , and that it suports the use of the PDSG gearbox .
By now all the boards mentioned have support for this gearbox ( elmod is soon, ore is allready ? )
as I dont own the asp ore the elmod , but I have several of the IBU3 and even more clark's tk 60 , I will say that on setup IBU3 wins( with pc software and setup guide as you go along) both uses USB to pc setup , on footprint, the clark wins, on sound, tricky as they are are both really good, but the clark have a hair' better transition on the revup-engine step , but overall pritty much alike . Both are continuously updated , and updates via usb to pc
