I have 101E's, you can refer to my past threads to gather lots of different info.
Spikes: I use Sistrum platforms underneith mine and I'm very happy, I know allot of others who use the same product and under a variety of different speakers and all feel the same way so that's what I would recommend.
Amps: I would sugest you try them both ways to see which you prefer.
Subs: again try them, I have not tried subs with my speakers but I did hear someone elses set-up with subs. I have a pretty good room and don't seem to be having any issues with bass, it sounds great and prefer my bass offer the one I heard with subs.
I noticed you mentioned your speakers are "D", do you know what the difference is from "E" and "D" models.
