Выбор цапа PCM1793+DIR9001 или WM8805 + TDA1541.
Добрый всем день!
Хочу заказать недорогой цап с ebay.
Подобрал вот эти два чуда китайской инженерной мысли, но поскольку это мои первые терзания на тему внешних цапов, то прошу помощи в выборе между ними!
Советы,критика - принимается во внимание все!
Система:
Источник 1. РС с выходом оптики и цифры 2. pioneer dv 696 (как временная мера, сидюк продал но выбираю новый под СД транспорт).
УМ - Denon 710ae
Ac - Klipsh rb 35
Цапы выбирал намеренно с usb!
Итак:
Upsampling 24/192 DAC KIT, USB input,mainboard PCM1793+DIR9001

ИЛИ
DAC WM8805 + TDA1541 1.0J I/V output OS/NOS
Structure :
Digital and analog stage
- input : SPDIF of multi-input (coaxial, USB, optical)
- I2S input at NOS mode
- WM8805 as digital receive stage + CPU control + SAA7220 + DAC TDA1541
- to use audio low noise transistor and JFET constructed for the I/V converter.
- 2 nd stage use JFET as first class buffer output
Power regulation stage
1. Individual 2-stages regulation power supply of +/-15V for Analog, +/-5V for Digital
( transistor + op-amp construction )
2.Working voltage: 0-9Vac / 0.8A x 2, 18Vac / 0.8A x 2
Deluxe and audio grade components selected
1) The use of 14 pcs 1uf multi-layer capacitor for TDA1541A chips
2) All high grade capacitors for the decoupling and filtering, OSCON capacitors for digital stage
3) High-speed with low resistance rectifiers C3S
4) Analog and digital power stages are using MOSFET and transistor for voltage regulation.
5) All resistors are using Military grade and DALE Resistors.
7) All gold-plated IC sockets
Remark: Sometimes, due to component procurement, some parts will be different from the photo, the principle is to use the same or high grade component for replacement.
PCB size : 225mm x 165mm x 45mm(height)
2mm thickness of double-sided gold-plated
155$ с доставкой.
Морально готов до 200$
Заранее всем спасибо!
