Is this a Vision EC DAC? I'm not familiar with Vision Hybrid. Is it a tube DAC?
Per the AVAHiFi Vision DAC page
http://www.avahifi.com/index.php?option=com_content&view=article&id=247&Itemid=241Three new models are available:
The basic
Vision DAC.This basic model provides the best possible musicality at the lowest possible price. It has one coax digital input and stereo analog output set, all executed with gold plated RCA jacks. Any previous AVA DAC, solid state, vacuum tube, or hybrid, can be updated to the basic Vision DAC.
The multi-input
Vision EC DAC.
The Vision EC DAC provides multiple digital inputs. Two Toslink optical inputs and two RCA Jack coax inputs that are switchable from the front panel. This allows connection to any available sources, including the optical digital output of your computer at the bit rates mentioned above. Note that a USB input is not provided because high bit rate USB computer output requires software driver programs, and we simply do not want to get into the software support business. The optical inputs provide the necessary computer interface. Of course, diehards can add a separate USB to optical or USB to coax converter box if they desire (available inexpensively from many sources).
The premium multi-input Vision Hybrid DAC.The Vision Hybrid DAC provides four sets of switchable digital inputs, two coax and two optical to serve all your needs. It decodes everything up to 192K 24bit material. It has our newest and best hybrid vacuum tube analog filter and output stageSteve
