Frequently asked questions about amplifiers and speakers, how to pair them, advantages and disadvantages of each type, etc
Class A, whether tube or solid-state, is the gold standard. Simply based on sonics and assuming it suits your system, speaker sensitivity and use case, the highest-fidelity amplifier design is class A. Speaker sensitivity combined with your amplifier’s power output determines the system dynamic range, an important consideration not to be overlooked. No Compromise Nothing […]
For hi-fi purposes, none. Class B is often used for radiofrequency broadcast amplifiers, where high power and low spurious RF emissions (sorry, no class-D in radio!) make it a great choice. On its own though, class B suffers from relatively high (crossover) distortion and is unsuitable for audio for that reason. Combined with a little
The one key advantage of class A topology is high fidelity, ie the best sonic performance. Basics Class A amplifiers deliver the smoothest, most euphonic sonic performance and the lowest objectionable distortion. That’s why class A is used in high-end designs despite its shortcomings and why the very best amplifiers are class A, where cost
Class D offers advantages in terms of high efficiency, small size and low cost, allowing small, powerful amplifiers to be produced cheaply. Pros & Cons High power and low cost are desirable amplifier traits and help explain the popularity of class D amplifiers in the low-cost, high-value sectors of the market. Class D delivers very
It depends on the system, sometimes yes, usually no. The sound pressure levels achievable with a hi-fi system are down to two parameters: amplifier power output and speaker sensitivity. Low-power amplifiers can create realistic sound pressures and dynamics, but only when matched with sensitive speakers. Do not expect a 30W per channel amplifier to offer
