Mathewm - I'm not sure I can tell you anything meaningful about the bass response of the S30s with the FX10. I would have to ask, "compared to what," and I wouldn't be able to answer because I didn't do any A/B critical comparisons to any of my other speakers or amps.
I use the FX10 in my office in a near-field setup with a pair of single-driver JohnBlue JB3s and love that combination with the music I listen to. The JB3s have a beautiful mid-range but don't go as low as the S30s and cost twice as much.
The only way to decide is to buy a pair and try them. One of the reasons the S30s are such an easy recommendation is that trying them will be cheap and easy, one of the pair I bought was $120 used. But they really are quite remarkable in every setup I've put them in.
