Great comments Chris.
Certainly it is inconceivable to have Bayreuth Opernhaus in ones room or Stadt Teater Munchen but I guess to be able to listen to good and great music one could strive to assemble an ‘optimum level’ audio system even if it is by using the raspberry pi/dac at the upstream and decent downstream amplification and loudsoeakers but importantly placing them in an appropriate listening room.
And then forgetting about all the equipment and everything else and soaking in the Bach Cello Suites or Wagner Tannhauser or Stravinsky Pulcinella.
