2 Class ab

以上幾部我只聽過 uniti 2 ,其餘未去聽過.所以未知分別有幾大
class d 真係會較為失真?另外師兄如果唔介意可否講我知你部amp係邊到有得試?
還有你現在部amp同你之前套前後級比較如何呢?
thanks

Class A or, (and to some extent), A/B amps are simpler designs which only require 2 devices, (push-pull outputs), in order to recreate both halves of the original waveform. Easiest way to explain it is the least amount of devices needed to go from input to output, the cleaner the sound. However, power-wise they are extremely inefficient, need about .5 hour warm up time from a dead start to reach full performance due to charging their huge toroidal power supplies… but they are by far the only way to fly when you’re seeking out the best.

Class D amps use a ton of internal switching devices, (which in turn degrades the original wave form) in order to achieve a very high power efficiency rating and a lower THD, (Total Harmonic Distortion), by using excessive amounts of negative feedback loop which is nothing more than recycled power which makes the amp more likely to clip.
