I am also interested in the Audio Alchemy DDP-1 DAC. Based on my understanding, for maximum performance, I would also have to buy the Audio Alchemy PS-5 upgraded power supply that is available for $595. I was told that the DDP-1 is completely balanced from the DAC chip to XLR jack including a 4-gang Alps potentiometer (one deck per phase per channel). The unit runs warm, but not hot. As noted above, I hope that someone adds their comments to this post.
