Measurements of Luxury & Precision L5 Pro were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Luxury & Precision L5 Pro test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.

I believe that it is important to do not make an absolute assessment of the device, but an aggregate assessment when working together with a headphones and taking into account external factors. This allows you to effectively reveal the potential of the entire set of devices or to make a more optimal choice of components.

Комментарий к профессиональному отчету Luxury & Precision L5 Pro
У L3/L3 Pro и L5 Pro из-за особенностей своей ОС поток в 16 бит подвергается доп. обработке и это похоже на следствие округления данных от транкейта. Может быть промежуточные данные передаются во float. К счастью, регулятор громкости работает корректно и при понижении уровня сигнала ошибка округления пропорционально уменьшается. В тестах усилителя амплитуда сигнала уменьшается через тестовый сигнал и соответственно спектры для малых амплитуд выглядят не так, как если бы это было при уменьшении через регулятор громкости.

Комментарий к профессиональному отчету Luxury & Precision L5 Pro Sharp
Тесты сделаны в 16 бит, т.к. в 24 бит наблюдается типичный транкейт. Графики получаются аналогичны L3 и L3 Pro. При воспроизведении DSD у L5 Pro такой же результат, как и с 24 бит. Вероятно, DSD переводится в PCM. У L3 и L3 Pro DSD воспроизводится чисто.
