Although the SS10 is no more sensitive than the HT3, and therefore will require quite a few clean watts, the impedance level and profile is, if anything, more amplifier-friendly. The impedance never falls below 4 ohms and is quite flat across the entire spectrum. I just sent my Van Alstine Insight off for an upgrade, and will be using a little AVS Onix 80 watt integrated amp in its absence--hooked up to one HT3 and one SS10. I'll let you know how that works out.
