Love the unit. Only problem was I needed to plug in a Wadia iPod transport and my CD player and it only has a single input. Inday Products to the rescue. Bought one of their DA4X-R switcher boxes for $129 and now I have 4 digital inputs available to play through my DAC without ever swapping cables around. Looks good, sounds good, works good. A very nice compliment to the single digital input Vision DAC preamp from what I can tell so far.
