Just a quick note for those that might be interested, but first of all, the disclaimer: I don't know Dan (OptoDX), never met him or talked to him before getting the OptoDx boxes and I paid full price for mine and get nothing out it by talking about it. I've had my OptoDX boxes for several week now and have taken them out of my system and added them back over 3 times now. I wish they were not as good at dropping noise and harshness in the upper region as they are. The OCD in me HATES adding more boxes and cables then I need to considering i'm only running an Innuos Statement to Mscaler to Dave to Empyrean. Even with the purchase of the Statement, the DX boxes get rid of a noise that the Statement still does not. I have mentioned it before and not sure if Dan said it was true or not, but I believe that the FPGA chip in the mscaler creates its own noise that no matter how good the server is, it will be sent to the DAC since the Mscaler comes after the server. If you have an mscaler, you definitely need to hear the Dx boxes in your system. With the 60 day money back guarantee, its a no-brainer. I believe your money is better spent getting the DX boxes vs upgrading the BNC cables, though upgraded BNC cables with the DX boxes is even better still. Also, even with the DX boxes, switching from the Innuos Zen Mini to Statement still made a pretty big difference in my system. The first thing I noticed when upgrading to the Statement was just how real all the instruments sounded. Also had all the other benefits of better bass, mids, etc. Unfortunately for our wallets, seems like EVERYTHING matters in this hobby.
