Default self professed newbie with LM4651/2's

hey guys.

a while ago i saw product descriptions for LM4651 / LM4652 setup on NSC's sites. i currentl have 5 pairs of said devices and am thinking about building them up into an amp..

my question to you guys is have any of ya's had much experience with these chips and have a design that use these chips which include a preamp / filter which is a bit more straightforward than the circuit in the datasheet, and is known to produce okay-ish results.

i also read something about connecting multiple 4652's to a single 4651 to increase power.. is this possible?

first post, so i better wrap it up.

regards glenneaux
