Two factors are making me consider this category of integrated amp. One is that I'd like a generous amount of power. The other is that I'm old! Why does that come into consideration? Because I can no longer lift heavy things without risk to my back. Any amp I get must be of a manageable weight, because occasions will arise when I need to put it in place, remove it, put it somewhere else, etc. My understanding is that Class-D integrateds can deliver substantial power while being relatively light in weight. Does anyone know of some good ones?
