In general amps with high current capability will deal with difficult , low impedance loads better, but , as noted, there is no single measurement or even sets of measurements that will tell you what a speaker amp combination will sound like. I have found it amusing how often you see the sound of a speaker or amp described by itself when in fact there is no such thing as the sound of a speaker except as driven by a particular amp or of the amp except as heard through a certain speaker. As a dealer I always suggested selecting a speaker first as it is considerably easier to find an amp that will work well with it than it is to find a speaker to match an amp. In the first case you know what the needs are, in the second you have potentials that could match many different speakers in different ways.
Importance of Damping Factor and Current for amps
I have read that amplifiers with high damping factor and high current delivery can provide deeper and more controlled bass, and also handle difficult speaker impedance loads. Is this true for both solid state and tube amps, whether separates or integrated???
