Should All Amplifiers Sound The Same?

Have you ever wondered why some amps just sound better with certain speakers? It turns out, it's not just audiophile hype. It's measurable, and it's largely due to amplifier output impedance. If you’ve ever talked about “synergy” or struggled to explain why your tube amp sounds different from your Class D amp, this is the science behind it. In this video, I show how three different amplifier types — with output impedances of 0.01 Ω, 0.50 Ω, and 1.00 Ω — interact with real-world speaker impedance curves. The result? Frequency response changes up to 2.50dB or more, depending on the speaker design.

KLIPPEL is an innovative leader in providing unique test equipment for electro-acoustical transducers and audio systems. Founded in 1997 by Dr. Wolfgang Klippel, the novel techniques developed for control and measurement systems of loudspeakers and other transducers are the result of over 30 years of fundamental research. This provides more accurate physical models of loudspeakers, micro-speakers and headphones valid for both small and large amplitudes. The focus is on revealing the root causes of signal distortion and defects and giving practical indications for improvements in design and manufacturing of audio products.
