Audio Garden's review
The PA10 stands out as one of the most serious portable amplifiers for audiophiles seeking uncompromising Class A sound reproduction. The absence of a built-in DAC allows it to be paired with the best external players, while avoiding redundancy.
While its size and weight might make it slightly less convenient than some other models, its performance, warm sound, and extensive connectivity make it a top choice for anyone looking to elevate their portable headphones. Even on the used market, it remains highly relevant and deserves its place among the classics of portable amplification.
