[QUOTE="undefined.za, post: 265308, member: 3032"] Thanks Ian. Part of what I find appealing about high efficiency systems is the huge amount of output headroom that one usually has. For example, your current pair of speakers uses drivers rated at many hundreds of watts, and, if I recall correctly, their net efficiency is close to 100dB/1W/1m. With 440w RMS of class A power, you must be able to break the windows! Besides that, because the drivers are working at far below their rated output power, their distortion characteristic is probably lower too. As you know, I am currently using a pair of speakers rated at 100db/1W/1m. Volume is a difficult thing to judge, however I am positive that I now listen at, on average, a (much) higher volume than I did with my Magnepans (rated at 90dB, I can't remember if that is at 1w or 2.83V). I do, however, suspect this may be due to insufficient amplification on the Magnepans... Assuming worst case at 85dB/1W/1m, would headroom be an issue at higher volumes? This is of course assuming that sufficient amplification is available. [/QUOTE]
