R-2R лестница в NOS небо


(стерео бармен) #1

NOS = non-oversampling, без оверсемплтинга (без фильтров перед превращением цифры в вольтаж).
R-2R — это способ PCM-конверсии в аналог, используется лестница резисторов. R-2R очень редкие ЦАПЫ. Сейчас практически все ЦАПы это дельта-сигма и, сильно реже, мультибиты.

Не знаю, как вы, но я отчетливо вижу тренд на появление все большего числа R-2R ЦАПов. Про MSB DAC и их OEM-модули даже и говорить не будем.

Новые Metrum Musette, Metrum Pavane, Metrum EVO все идут с проприетарными модулями Transient.

Питер Квортруп рассказал, что они проектируют и уже есть прототип. По слухам, прототип играл на выставке в Мюнхене и всех выиграл.

В чем прелесть R-2R цапов — это временная точность, а это значит предельная быстрота и точное интонирование в музыке. Все как мы любим. Часто в укор таким ЦАПам ставят слабую обработку концов диапазонов — баса и верха, но за дорогими R-2R цапами это не водится.

Было бы интересно послушать, конечно. Интересно, что скажет начальник транспортного цеха :grin:

Потрясно все аппараты внутри выглядят.

ИМХО правильный тренд! :smile:

Прослушав много ЦАП-ов понял что не воспринимаю звук дельта-сигмы. Даже уровня Брикасти М1 и Дебюсси (хотя последняя есть некий гибрид технологий).


(стерео бармен) #6

Пост щедро оплачен :grin:
Rockna представила для новых ЦАП Wavedream DAC с дискретными модулями Rockna RD-1 и Wavedream DAC Signature с с дискретными модулями Rockna RD-0.
Теперь не Femtoclock, который уже у всех парней, а свой Femtovox clock!

RD-1 с 26-битной лестницей, а RD-0 с 27-битной. Ну и DSD 256.

La Voce S2 is for those who want to eat cake without being explicitly reminded of flour, butter and sugar.

If you find Sabre-rattlers all much of a muchness, the Aqua unit could well be a better fit for your tastes, especially if your music tastes closely align with that of your average Pitchfork or Uncut reader: The Hold Steady, Autechre, David Bowie.

Короче, надо бы послушать!
