In Reply to: Sound quality of amps for horns (0.3 watts?) vs typical 5 watts posted by RG on March 25, 2005 at 05:05:39:
Hi,
the truth is that in domestic environment You will never need more than one Watt of electrical power with speakers of 90 dB/8 Ohm, not to mention those super efficient horns.
I believe that people who talk about realistic live levels of 120 dB are not very familiar with live music and certainly do not know the difference between concert hall and living room. To them - feel free to listen to levels with peaks of 120 db but before that don't forget to say goodbye to Your hobby and to Your hearing. You will soon become former audiophiles.
As to the main theme - first milliWats are best in case of tube amps and gainclones. They are the worst for discrete transistor amps. It's measureable. Most amps have quite significant distortion figures in that wattage range. These distortions contribute to the characteristic sound of the amp. Different distortion spectra can in particular give objective explanation for subjective differences between tube and sand amps.
The fact that we listen to the first Watt most of the time ('normal levels')explains that there is little correlation between standard measurements of amps and their subjective quality.
To Your first question - 0.3W is more normal than 5W
To Your second question - efficiency is not the key factor, 90 dB is ok in domestic environment even with little low wattage amps if it is true 90 dB/8 Ohm
