The OP didn’t mention two issues
1) Does he listen to SACDs? Does he need Blu Ray?2) Budget
I use my Sony as a transport into a Bryston DAC3, which accepts HDMI. For SACD, the DSD is outputted from the Sony. If your budget can stretch that far, then you can use the Sony as a transport. The Bryston has 4 HDMI inputs so you can add a cheap Sony Blu Ray if you wish, or you could sell the 5400 and just the the Blu Ray as your transport for all silver discs
