+1! I have 5 feet between my SL3s and the wall behind them, and RPG Skyline diffusers on that wall. Works much better than any alternatives I tried. Excellent soundstage and imaging.
Personally, I've used spikes (with small saucers under) on a hardwood floor, but now use double thickness E.V.A. anti vibration pads under my SL3s. I find that over all clarity is improved with the E.V.A pads.
In my experience, absorption is desirable at the first reflection point of both speakers. I use diffusion to good effect on the front wall 58" behind my SL3s.
I *suspect*, based on my experience with SL3s, that diffusion may be best IF you could bring the speakers about 5 feet out (I use RPG Skyline panels). If not, then absorption may be te better bet.

I tried class D Red Dragon monoblocks with my SL3s. The sound was very clean but two dimensional and bass shy. An apparent impedance mismatch. (I run the SL3s from the 1 Ohm tap of my Music Reference RM 200 Mk II hybrid tube amp).

Try sitting so that the distance from chair to speaker is about 1.1 times the distance between the speakers (measured between the spots where the flashlight reflections are).

Personally, I found that double thickness E.V.A. Anti vibration pads (< 50 cents each) worked better than spikes. Greater sound clarity, better imaging, etc. Worth trying.

Place a quarter between wooden floor and spike. On the other hand, personally, I found that double thickness E.V.A. Anti vibration pads in lieu of spikes yield a clearer sound and more focused soundstage.
