“I’m sure a lot of people reading this review are wondering if the A 21+ sounds a lot like the original A 21. These thoughts are perfectly appropriate when nothing but a plus sign has been added to the model name. As a previous long-time owner of the original A 21, I feel confident in saying the A 21+ does in fact sound similar. However, I also feel confident in saying the sound is not a carbon copy.

In a sense, you’re getting an A 21, but with moreof everything. Specifically, the A 21+ offers more impressive dynamics, a more accurate stereo image, wider stereo separation, and I heard more impressive control over my speakers’ drivers on a regular basis. Like its predecessor, the A 21+ still punches well above its price point in overall performance and is still an amplifier that does most things right.”
