I have had my Oppo bdp-103 modded with the VanityHD for about a month now. I am very happy with it. It has worked flawlessly, and it sounds some levels better in my system compared to the Oppo BDP-105 I had before (using analouge out). I have tested both minidsp opendrc-di and dbx4820 to receive the digital signals from the VanityHD, and as I said, no problems. I warmly recommend this product.
