.Im looking for an amplifier with good power but tame on the highs. still curious about the rotel
then you might to pass on the rotel.
Best amplifier for klipsch heresy 3 speakers.
Because of the high efficiency drivers used in this speaker, the back EMF is pretty high. This means it will exhibit some harsh behaviors if you use an amplifier that has lots of feedback. This rules out 99 44/100ths percent of all transistor amps. In addition, the crossover will not work correctly (horn will operate out of band and become 'honky') if the amplifier behaves like a voltage source. Again, this rules out transistors. For more information about how this work, read the article at this link: http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.php Do your self a favor- find a tube amp in your budget. There are no inexpensive transistor amps that will do this speaker justice. |
If you want a transistor amp that sounds any good on that speaker, its going to make some heat too. If you don't mind compromising, then any amplifier will work. The 'tame on highs' thing is where you are most likely to get in trouble with most transistor amps. Transistors have non-linear capacitive elements in their junctions. This contributes to distortion. It is also magnified by greater amounts of current through the device. To control the resulting distortion, feedback is often used. Both contribute to odd ordered harmonic distortion, which the ear interprets as both brightness and harshness. That is the physics and the physiology of the situation. If you are dead set on a transistor amp, put a level control in series with the tweeter so you can tone it down. It won't be ideal but it will work. Alternatively, you could get a speaker that is designed to work with transistors. The speaker you have now does not sound right with transistors because it was designed on and for tubes. |
