Waversa VDAC MkII Tube DAC
VDAC uses a vacuum tube analog amplifier, so the natural secondary overtones (harmonics) will come out so that there is no need to deliberately create secondary overtones (harmonics) in the digital part. By using the vacuum tube as an amplifying element, all the advantages of the vacuum tube are saved and the shortcomings are overcome with excellent circuit technology, resulting in the highest level of high-end DAC.
The digital input unit (USB, Network) developed by Waversa, uses WAP signal processing - Waversas's own algorithm, multilayer energy transfer technology applied to four D / A converter chips, transformer I / V conversion, CPU controlled bias.
Featuring unrivaled digital technologies, such as OPAMP and transformer analog stages without resistors and capacitors, with the highest-end tube amplifier technology. Quad SABRE based design is a unique implementation whereby each chip handles one channel with limited frequency spectrum. Two chips per channel.
WVDAC MK2 Western Electric Tube-based Digital to Analogue Converter utilizes 4x WE408A tubes and 6x4 rectifier tube.
- FPGA based built-in high-end up-sampler(WAP) up-to 1.5MHz/24bit
- Linux 4.9 with 1GHz TI OMAP Processor ( ARM CORTEX-A8 )
- Quad SABRE based design
- Waversa's custom energy transfer technology applied
- Waversa's custom-designed computer-controlled automatic tube bias adjustment feature
- No discrete parts are used for the signal output stage
- I/V Converting with Lundahl nickel amorphous transformer
- Full balanced output stage with Western Electric 408A tube with Lundahl output transformer
- D/A converting with CDP/DDC via Coaxial, AES/EBU Input
- File play with PC/MAC via a USB port(UAC2 Compliant), DSD256 Support
- Network play via Ethernet port(DLNA, Roon Ready, AirPlay, WNDR)
- DSD256(Native) Support(USB, Ethernet)
- System Update via Network and SD card
