I had the XDA-1 as well. Notice I said had. With the Emotiva cd player and XPA amp, I found the end result harsh and etchy. It was Emotiva's first attempt at a DAC. They claimed it had lossless volume so I bought it to use as a digital pre. Later on they finally admitted it had lossy volume. I bought an Pure i20 dock to digitally connect my iphone to the dac. It was super bright, and unlistenable. I'd recommend Schiit or Cambridge or Parasound's new DAC.
