When this is ignored, issues such as higher harmonic distortion and noise, a low damping factor, and bass roll-off can occur.

The impedance values of the headphone and source should not be the same, and a general ‘ rule of eighths ’ has been adopted – that is, the headphone impedance should be at least 8 times greater than the source impedance. Impedance matching is the interaction between the source and the headphone and is key to high-quality headphone audio reproduction. Sensitivity (or efficiency) is a measurement of headphone volume at a specific power rating. Calculating headphone load impedance is very complicated as it is made up of a combination of resistance, capacitance, and inductance, and is defined as a ‘reactive load’. Impedance is one of the basic specifications of headphones ( load impedance ) and audio sources ( output impedance ). The Importance of Impedance in Amplification This is key to understanding the differences between the amplifiers. Hybrid amplifiers are more subtly sorted by their implementation.īut before we dive into the details defining the types of tube amps, any discussion of amplification needs to start with a review of the concept of impedance. Full tube amplifiers are separated by their construction, between those with output transformers and those that are output transformer-less (OTL).

Furthermore, each of these two tube amplifier varieties can be subdivided. Headphone tube amps can be divided into two main categories: full tube amplification and hybrid amplification. In short, tube amps are NOT all the same and NOT all tube amps will work properly with all headphones. This is due to large variations between types of tube amplification and the real-world impacts on how these differences interact with various headphones. Selecting the right tube amp to power your headphone collection can be a more complicated process than choosing a solid-state amplifier0.
