ct like a nearby cricket quietly chirping will resolve clearly, while a lar=
ger sound object like some rocks falling in the midground will sound obscur=
ed?

Any thoughts on how a recording made with Jecklin's older OSS (Jecklin Disk=
)design specifying 16.5cm spacing might compare to a recording made with hi=
s later modified design specifying 36cm spacing?
