I have a Marantz sa8005 and use it for a Dac along with jrivers it plays 2.8,5.6 DSD Flac and so on do you think that a McInTosh D150 pre amp -Dac would sound better than the Marantz Sa 8005 ? I have a Classe pre amp and Classe amp . This is used only for to channel System . What do you guys think would the McInTosh D150 be a upgrade ?
