Hi everyone, I found one unit of unused mini system with double cassette deck, which I am tempted to buy. I noticed that this unit has ability to play VCDs and Super VCDs. When I checked the product brochures of the manufacturer for further information, I found that there is another version of this system which is without the VCD read capability. This sans VCD version has "Dual 1 bit DAC" whereas the VCD version has only "1 bit DAC". Could anyone who is knowledgeable tell me whether the sound quality is affected by the omission of the second DAC? Should I grab it or should I just pass up on it? The product in question is JVC MX-D402T (sans VCD) & MX-V608T. Thanks in advance for your input
