Many amplifiers, regardless of class, require some increased volume setting to properly drive certain speakers. It is usually the interaction between an amplifier and the speakers themselves that determine if the “dynamics” at lower volume fulfill your specific desires. Do not go down the tube vs ss, class AB vs class D thinking there is a simplistic formula that will work for your hypothetical speaker. I wish it was that simple as it would have saved a lot of time and money (but then what would have been the fun in that…)
