key here is compression i find.... do as above, find a couple nice sounding snares, (using FL as example).
Route each snare drum to a seperate mixer channel, and EQ as above... or sometimes if u find sum good quality samples eq all from the same channel.
If you send them all to different channels, then send all them seperate channels to a "send" channel (again using fruity as an example) and put a compressor on it. I usually take the threshold down to about -15 - -20 db. put the ratio to 4
0 or maybe a bit higher... and then adjust the gain until its sounding sweet and punchy. And you should have a nice snare sound...
Hope this helped, il try explain in more detail using pictures and shit if u need. Im just about getting the hang of making sweet drums, still alot to learn when it comes to basslines and melodies and such tho
*EDIT*
forgot to say, once you have added all the effects... add some slight distortion to the send channel to get it sounding a bit gritty, then bounce/resample, whatever you wana call it, then put it into your track
