Добрый день.
Подскажите непрофессионалу, пожалуйста, что из себя представляет вот такая модель ЦАПа:
AMC DAC8
* 4 Digital Inputs -- 1 Optical + 3 Coaxial, 2 Outputs -- 1 Digital (BNC) + 1 Analog
APPLICATIONS AND FEATURES
* The AMC model DAC8 was designed to meet professional quality standards for Digital to Analog signal conversion.
* The highest grade of components are used throughout with critical components selected for the sonic performance.
* Double sided, through hole plated, Printed Circuit Board.
* The AMC model DAC8 provides 4 selectable S/PDIF inputs, 3 coaxial and one fiber optic.
* The DAC8 can automatically lock to either 32 KHz, 44.1 KHz or 48 KHz digital sampling rates for use with laser disc players, CDчХ or DAT machines.
* The AMC model DAC8 uses the latest generation of bit stream continuous calibration ultra-linear Digital to Analog Converter, with inherently low jitters.
* For those users with digital recording capabilities, the DAC8 has a digital output for connection to DAT, MD or DCC type machines, thus maintaining the ultimate in recording quality
* The AMC DAC8 provided an accurately calibrated output level in accordance with the EIA (Electronic Industries Association) recommended standard of 2 volts. This output level provides the best possible performance particularly for home theater users.
* The fiber optic input provides electrical isolation from Laser Disc players, thereby avoiding conducted interference from Video sources into the Audio chain.
* The superior performance of the DAC8 will provide not only improved technical specifications to your system, it will also significantly upgrade its sonic qualities.
SPECIFICATIONS
THD 20 Hz - 20KHz and SMPTE IMD
0.005% A-WTD at 2Vrms
Signal to Noise Ratio
104dB ??wtd
Output Level
2V rms
Frequency Response
20 - 20 KHz, + -0.3dB
Channel Separation
90 dB
Resolution
18 bits
Linearity up to -90 dB
+/-0.5dB
Input automatically locked to 32K, 44.1K and 48KHz SPDIF digital signals.
PHYSICAL PROPERTIES
Dimensions (W x H x D)
430 x 82 x 300 mm
Net Weight
4.2 Kgs
Насколько это начальный уровень или это все-таки ближе к середине ?
Beat stream -- это мультибитный ЦАП ?
Есть возможность купить его за $130. Не знаю, стоит ли.
При прослушивании на моей системе: ламповый усилитель "Ностальгия"+ мониторы Клячина + Denon DCD-725 разница практически не заметна. Есть небольшое отличие во 2-ом концерте Рахманинова, на джазе и романсах (голос) я разницы не ощущаю. К этому присоединяется и моя половина.
С уважением. Сергей.
