I have been using a Sony DVP-S7700 as a transport connected to my Music Hall 25.2 Dac which has some slight mods, including Burson V7 Vivid opamps and a Gold Lion 12AU7 tube. Burson has been kind enough to provide me with samples for a new project to mod my DVP-S7700 and install DIP 8 sockets and replace the OPA2134 factory opamps.
Phase one has been completed, removing the soldered OPA2134 and replacing them with DIP 8 sockets.
Phase two is waiting on some DIP extensions from Burson, it's too tight to install the V7 opamps due to the location of some capacitors. This will hopefully make it easier to swap without having to remove the analog audio board every time.
Please follow along for future comparisons between the analog audio board with the Burson opamps compared to the external Music Hall 25.2 Dac using the Sony as a transport connected through CoAx. I will also be comparing the older V6 Classic, to the V7 and OEM OPA2134.
