In a power amplifier (main amp), the power (measured in watts) generated drives the speakers to achieve a high volume level. While modern digital power amplifiers usually do their job with low power consumption, little waste heat and high performance, most valve or Class-A amplifiers sound sexier but traditionally generate more heat and have higher power consumption. They rarely produce in excess of 50 watts rms. For those of a green disposition and not wishing to heat their house with an amplifier, the best compromise between environmental protection and good sound is the classic transistor amplifier in A/B operation.
To all English speaking friends of LowBeats
Thanks for visiting LowBeats Magazin. At present it is an all German language site, with just the odd feature and review in English. We are working hard to present much more content in English and aim eventually to have a full dual language magazine for our readers. In the meantime please bear with us whilst we work to achieve this. It will be worth the wait!
