[QUOTE="audioholic, post: 6606653, member: 549629"] None of my comments touched on, or even implied anything to do with damping factor. Damping factor is an outside factor not being discussed in this thread. Zed's comments were based solely on power output in watts as related to impedance, and the corresponding db increase/decrease. Hence, my comments were based on the same factors. Look at my conclusions if you dont believe me, I clearly was talking about power output, and headroom to handle dynamic signal variation... nothing to do with damping factor in any way. And, you can say 'dramatically reduced' by halving impedance, but so long as the damping factor remains within an acceptable level, as one would assume based on running an amp at an impedance it was designed to handle, your damping factor addition to the discussion really is just a hypothetical assuming the worst case scenario (that the amp will dip below an acceptable damping factor when driven to 2ohms or 1ohm versus 4ohms). If we are going to assume the amplifier will have poor damping at an impedance its rated to handle, why not carry your assumption further, and suggest the amp will display poor damping even at 4ohms?
