Измерения усилителей проведены Романом Кузнецовым на программно-аппаратном комплексе RAA.

Всё тестируется как "черные ящики", без учета стоимости и статусности. Это главный принцип измерений и разработки тестов в RAA.

Из-за большого количества протестированных устройств затруднительно просматривать каждый отчет в поиске продукта с необходимыми характеристиками усилителя для наушников. Для этого и была создана эта страница сравнения, где можно быстро сравнить устройства по основным параметрам и перейти в отчет или специализированные сервисы on-line сравнения.
