Upgrading my digital system

Hey folks! I’m thinking about upgrading my digital system: northstar design model 192 transport and luxman da-06 dac. Few times I listen to cd but usually hi res files with an aurender linked to the dac. My budget is 8-9k euros. I’m not using tidal yet -  i don’t know if mqa option is worth and aurender can stream mqa with extra cost conductor  app). My first question is to keep the transport and go for a metronome le dac 2 or meitner ma3 or buy a cd player with dac like metronome le player 4 or ayon cd 35 signature. My last choice would be keep on saving and get a bartok or msb discrete. I’ve got spectral system matched with marten speakers. Any help would be appretiated. Thanks!!
