Class-D or switching amps, any opinions on??


Does anybody have experience on Class-d or switching amps vs either a/b or traditional amps?? I have heard people knock them for limited ability at the low frequencies. However, I listened to a Linn amp not long ago and could not hear it wanting for anything. I want to hear a Rotel switching amp to compare. Why buy a massive 90lb amp thats a space heater if you dont have to, right???

I have been using the Tact digital amps for sometime. The lower noise floor has allowed me to understand words in familiar songs which had been previously buried in the mix while using tubes and class a/b solid state. I interchanged the Tact with my CJ 2500A and my ARC vs55 for a few weeks, but finally I could no longer tolerate the additional noise in the analog amps. Nothing is perfect, but digital amps now offer lower noise and greater resolution than analog, and they can tailor their response curves and loudness contours to taste (and speaker demands) with no additional distortion penalty. It can only get better!
I thought the question was "Does anybody have experience on Class-d or switching amps vs either a/b or traditional amps??" The question seemed general enough, not technical in nature. "true digital" seems to me as elusive as "true class A". Hard to get folks to agree on the term. Class D means "not an analog amp" to most of us. FWIW Tact amps can be digital input only, or may have an analog input in addition.
