Digital Amps? Marketing Hype?
"So you are right Kr4, I do need to do some research;" Yes. There's a lot of info out there. Try the Tact and Tripath websites for a start. "however, it seems to me that class D amps are not digital but rather 'described' as such." Depends on your definitions. I tend to agree with you but I am not bothered by this minor shading of word use. "I am not familiar with the digital ammps you mentioned, but it seems they behave as DAC's." Some do. "That is, they pesent to the speaker load a signal which approximates an analog signal. It is the physical limitations of the drivers (load) which actaully produce an analog signal. Your thoughts?" All have a reconstruction/HF filter at their outputs, so that they output a smoothed analog signal. Relying on the speaker/crossover to do this would be an uncertain application. |
Jlamb, I have been running a Bel Canto EVO for about a year now and couldent imagine being with out it. I cannot find a weakness with it. No hype just stellar performance. I think for the price its a "steal"... I have also heard many good things about the Spectron... In fact the Spectron may be a better bang for the buck buy?.. But like i said i couldent imagine being without the Bel Canto. I havent heard much about the Tact. Here are some direct links to the Bel Canto EVO white paper and the Spectron amp details. These should answer most of your questions.. I dont think someone could go wrong with either one of these.. http://www.belcantodesign.com/index2.html http://www.spectronav.com/tech1.html Steve |
