Dave Smith Instruments SYNTHESIZERS

IMO the PEK is a better build quality, so I think design choices were  
made with P08 to keep the cost down so they could include more voices.
In the end only Dave can answer why certain choices were made in the  
production of the PEK/PER & P08

My own take is that the voice structure and resulting complexity of  
the evolver sounds often makes more than 4 voices overkill.
If you need more voices, pick up a PEK, MED or PER to augment -
I think It's great that DSI offered these various models. - ( I wish  
moog would offer a 4 voice voyager expansion like the PER)

That being said, an internal voice board upgrade would be a cool option.
I might not get one because I already have a PEK & PER though.

PS: The recent  ebay prices on PEKs have been *ridiculously* low (~ 
$1000)
truly great deals for an awesome synth.
