Jadis JP30

Does anyone have experience with the Jadis JP30 preamp? I like the JP80 but it’s almost double the price of the JP30. Trying to decide if the JP30 is good enough. As far as I can tell the JP30 has similar layout to the JP80 but it’s missing the point to point wiring, smaller power supply, volume pot vs resister ladder volume, and probably missing the CD output tube buffer. 
 

i think dealers carry the Jp80 but I don’t see them having the JP30 for demo. Any feedback would be useful. Thanks.
